It is always interesting to study the history of weddings of different cultures. One can find that some of the old traditions have been carried forward to the current weddings.

In Italy, to this day marriages are not performed during Lent and Advent in May or August. Sunday was declared the best day for the marriage and June was (and is) considered the ideal month to marry. This is based on the Roman goddess Junio, representing safety of home, marriage, and childbirth.

In some families the marriages were arranged by the families of the bride and groom. A male relative of the groom would visit with the father of the intended bride and ask for her hand in marriage. Sometimes a matchmaker was used to carry a message to the intended bride’s family. Once an agreement between the families was reached, the couple was declared engaged. The prospective bride was expected to immediately start gathering clothing (even for her future husband), furniture, and other items for the home. This became known as the bride’s ‘trousseau’. If the engagement ring contained gold it was not to be worn until she received the gold wedding band as it was seen as bad luck to wear gold without being married.

In olden times a great deal of the Italian wedding traditions consisted of warding off evil spirits. The groom would be sure to have something iron on his person to ward off the evil eye. The wedding veil was for the purpose of warding off evil spirits they may try to attack the bride and tearing the veil after the ceremony was considered good luck. The bride was not to have a complete bridal gown until the wedding day. It was to remain incomplete until she walked down the church aisle. Presumably a final stitch was made somewhere on the dress at the entrance of the church. The groom would wait at the front of the church and present the bride with a bouquet of flowers and herbs, to ward off the evil spirits.

At other times the groom would pick the bride up and walk her to the church. In this case a log and a saw would be placed in their path and they had to saw it into two pieces to show their union. If the bride walked to the church, without the groom, the local people often put things in her path such as a broom, beggar, crying baby. How she handled these items showed if she would be a good wife, mother, would be kind, etc.

In the ceremony the groom stood to the right of the bride, thus freeing his sword hand, just in case someone tried to steal his bride. Ten witnesses were required to make the ceremony official; hence the need for a large bridal party. They were dressed like the bride and groom to confuse the jealous spirits. The bride carried (and still does in most weddings) a silk or satin purse for guests to deposit their money gifts in as a way to help with the expenses. Another way money was raised was by the best man cutting the groom’s tie into pieces and selling them to guests at the wedding.

Following the ceremony the bride and groom were pelted with almonds (in mesh bags), three for children and five to seven to promote fertility. In ancient times a loaf of bread was broken over the bride’s head to represent fertility. At the end of the wedding the bride and groom broke a vase or glass into pieces with the number of shards representing how many years they would be married. Mothers-in-law sat at a table and kept a record of the repayment of favors or money which needed to be witnessed (this is still done in some of today’s ceremonies)

Most of the ceremonies started with mass in the early morning, followed by music and dancing throughout the night. Food was, and is, a large part of the wedding. Thirteen or more courses were ordinarily served (a large meal is still served at today’s weddings); this represented the union of the couple and their families.

It’s amazing how many wedding traditions still remain even though they may have evolved somewhat to reflect today’s society. Incorporating traditions based on heritage is often a good way to honor the old while celebrating the new.

The balance sheet, also called the statement of financial position, contains three items: assets, liabilities, and stockholders’ equity. It is dated at the moment in time when the accounting period ends. The accounting equation that is a big part of the financial statements is: assets equal liabilities plus stockholders’ equity. When working with a balance sheet: the total assets must equal the total liabilities and equity.

The first part of the balance sheet is assets. There are two main categories of assets: currents and long-term assets. Current assets are expected to be converted to cash in the next twelve months or one business operating cycle (if longer than a year). Cash is the most liquidated asset. Short-term investments are stocks and bonds that a company intends to sell within the next year. Accounts receivable are the amounts the company expects to collect from customers. Notes receivable are amounts that the company expects to collect from a customer who signed a promissory note. A company also includes inventory, which is a current asset, into the balance sheet. Prepaid expenses are also a part of the asset side of the balance sheet because the company will benefit from them in the future.

Long-term assets include plant, property, and equipment, intangibles, and investments. Plant, property, and equipment (PPE) include land, buildings, computers, store fixtures, etc. Accumulated depreciation is also included on the balance in the long-term assets area. It is the amount of depreciation from PPE at the end of the year. It is subtracted from the cost of PPE to determine its book value. Intangibles are assets with no physical form such as patents. Investments are long-term assets because the company does not expect to sell them within the next year.

The second part of the balance sheet is liabilities. Liabilities are also split into two categories: current and long-term liabilities. Current liabilities are debts paid within one year or one operating cycle. Accounts payable is the company promises to pay a debt arising from a credit purchase. Income taxes payable are tax debts owed to the government. Short-term borrowings are notes payable that the company has promised to pay back within one year. Salaries and wages payable are amounts owed to employees. Long-Term liabilities are payable after one year.

The last part of the balance sheet is stockholders’ equity. The Stockholders’ equity is assets minus liabilities. There are two parts to stockholders’ equity: paid-in capital and retained earnings. Paid-in capital is the amount the stockholders have invested in that company. The basic part of paid-in capital is common stock where a company issues stock to the stockholders as evidence of their ownership. Retained earnings are the amount earned by income-producing activities.

I hope this helped explain the parts of the balance sheet.

There are many misconceptions about fashion stylist jobs such as these jobs are easy to get, one can lead a comfortable life after getting these jobs and one doesn’t have to work very hard to get ahead in this field. While these jobs are comfortable and offer flexible working hours, in order to get ahead in this industry, aspiring personal stylists should know a few things and listed below are 4 important must know facts about fashion stylist jobs.

#1 – Fashion Stylist Jobs are About Glamour but Also about Hard Work – Most aspiring stylists believe that becoming a one is easy and can be done by anyone. Although, this is partially true, in order to become a successful stylist, students have to work hard while they are studying to become stylists. In addition, for the first few years aspiring stylists may have to spend a lot of time and energy researching about the latest fashion trends so that they can help their clients get the desired look.

#2 – It’s All about Research – An important part of being a fashion stylist is researching the latest trends and colour schemes. Although students are taught various important things about fashion while they are training for fashion stylist jobs, it is important for aspiring stylists to remember that after they get a job or while they are on internship with a company, they will have to spend many hours a day studying about colour patterns and matching colours to skin tones, hair tones and body structures.

#3 – Fashion Stylist Jobs Involve Being Creative – Most people believe that there are hard and fast rules set for stylists however, the truth is that fashion stylists can experiment and be creative as long as they know what they are doing. An integral part of the job involves using one’s imagination and creativity to make clients look good. If you have a good imagination and can vision ideas then you may be ideal for this job.

#4 – The Sky is the Limit for Those Who Try – There is a lot of scope in the fashion industry and aspiring stylists who are looking for fashion stylist jobs can get success shortly after joining a job provided they are ready to follow the rules of this industry. Hard work and flexibility are two important rules of this industry and stylists who are ready to go the extra mile can easily accomplish their goals. Remember, to become a stylist the first thing that needs to be done is to get accredited from an institute that can help you achieve your goals.

 

In the olden days a career in finance did not offer anything more than a back-office recording keeping job. A finance person was understood to be a record-keeping person in an organization.

However, with the evolution of business landscape, the role of finance has evolved and become more challenging. In today’s organization a finance person occupies a much broader role involving decision-making, planning, controlling the financial operation of a business.

Within finance, one can find a variety of job roles that are not limited to just the accounting field. You can explore financial career options in various industries such as financial service, financial planning, fund management, regulatory compliance, trading, financial management, and so on.

These different jobs require you to have completely different skill sets, and you can choose a financial career that suits your personality and skill level.

If you are analytically oriented, you can choose a career in risk management, where your job is to measure and manage the risk faced by a bank or a financial institution. Alternatively you can also join the insurance industry as an actuary where you ass the risk of loss, and design and price new insurance products. These jobs require number crunching skills. You are also expected to be very diligent as a small mistake can turn into big losses.

On the other hand, if you are a very outgoing person and like meeting people, you may be better suited for selling financial instruments. You may want to join a bank or an insurance company, and promote their financial products to prospective customers. In a bank, you are expected to sell their financial products such as deposit accounts, credit cards, personal loans, home loans, etc. For a career in sales, most organizations provide you a thorough training on their products and common techniques for selling. You are expected to be a go-getter with the ability to close deals quickly. In most financial services institutions, you are paid a decent salary and a commission, which is based on your sales targets.

One more lucrative career option is in trading. As a trader you use your employer or client’s funds to trade in financial products such as equity, bonds, currencies and currencies in an attempt to make a profit. Traders study the financial markets and identify opportunities to make profit. This is a high stress job and requires you to have strong analytical skills and a tough attitude. A career in trading also offers good salaries with bonuses and incentives linked to your performance.

While these are a few important career options available in finance, a person interested in this field can choose from a much wider array of job roles. Best of luck with your financial career!

If you’ve never heard of Collembola, you’re not alone. Until recent years, it was thought that these soil borne creatures were essentially harmless. Even doctors vehemently denied that springtails were likely to infest human hair and skin. Folks who suffered from chronic itching, biting and crawling sensations were often considered delusional, but that mindset is slowly changing. Mounting evidence suggests that these micro-tiny pests can be surprisingly invasive.

Thanks to the tenacity of folks like Dr. Frans Janssens and his colleague, Dr. Kenneth A. Christiansen, the scientific community is beginning to recognize that springtails can pose a very real threat to human comfort when present in large numbers. The two researchers collected scores of reports from homeowners, doctors, and pest control operators in several countries, including many regions of The United States. Within the gray areas between casual testimony, scientific observation and concrete medical documentation, a startling picture emerged. Collembola are everywhere, and it’s not impossible for them to latch onto humans and animals.

As inhabitants of fertile soil, springtails are likely to be found just about anywhere. The more you water the lawn and apply fertilizer, the happier they’ll be. They are considered the most abundant arthropods on earth. Since prehistoric times, they have survived frigid winters and very hot summers, but their numbers decrease exponentially under dry conditions.

Pet owners are particularly vulnerable to collembola infestation. Dogs and cats who trample through moist soil or wet grass can pick up springtails and transport them into the home; however, it’s not likely that springtails will stay attached to pets like fleas unless an animal’s immune system is compromised (for example, if there’s a fungal infection of the skin.) Springtails are easily transferred between humans and animals. Close contact isn’t necessary. These acrobatic creatures can jump three to four feet. You may not always notice them catapulting through the air. They can be smaller than the head of a pin.

If the thought of a few springtails in the house makes you paranoid, relax. Their ability to divide and conquer will largely depend upon environmental factors. Do you enjoy growing potted plants indoors? Does your basement tend to flood after a good rain? Can you smell mold behind the bathroom wall? Are you still waiting on a plumber to fix that leaky pipe under the kitchen sink? Who was president the last time you cleaned your air ducts? A moist, moldy environment is like Disneyland to a springtail.

Getting rid of an advanced collembola infestation can be difficult because springtails aren’t classified as insects. They are defined as hexapods, primitive ancestors to modern day bugs. According to organic scientist David Glassel, chemical pesticides have no effect on the hexapod. Only natural insecticides will do the trick, and the best remedy is cedar oil.

Step By Step Guide to Eliminate Collembola Infestation:

1.) Treat yourself and your pets with a topical cedar oil insecticide approved for use with humans and animals. Avoid cosmetic or aroma therapy grade cedar oil. It’s not purified, and it usually comes from certain forms of cypress trees. Cedar oil that is formulated for home protection will kill ALL TYPES of parasites on contact, including springtails, lice and all forms of mites. If you’re tempted to use an over the counter kit designed for lice control, don’t bother. It won’t work, it’s not enough to cover large areas, and it’s just plain not good for you. Such products contain Lindane, a chemical banned for use with animals by the Environmental Protection Agency.

2.) Spray couches, beds and carpets with a fine cedar oil mist. A proper household formula will be very light and pure. In other words, it won’t stain fabric.

3.) Use a cedar oil fog machine to penetrate unseen cracks and crevices in the home. Normally, fog machines are considered optional, but advanced springtail infestations require aggressive measures. If you believe your infestation is severe, or if you’ve actually SEEN large groups of springtails moving over floors and walls, don’t mess around.

4.) Use the fog machine to treat air ducts or hire a professional air duct cleaning company. Many people are shocked to discover they have mold in their air ducts. It is not uncommon for mold to develop in your heating and cooling system from the condensation of your air conditioner. Springtails feed upon mold and thrive in moist conditions. Mold can also aggravate asthma and allergies. Air duct treatment addresses all of these difficulties.

5.) Purchase the highest quality furnace filters available at your local store. Filters designed for allergen and dust mite removal are best. Change filters frequently.

6.) Hunt for places where moisture accumulates. Patch leaky roofs and pipes. Seal cracks around basement windows. Pay special attention to bathroom walls and cabinets under sinks.

7.) Remove household plants, especially decorative trees sitting in large potted containers filled with soil. Remember that springtails can be transported directly into your home via bags of potted soil.

8.) Take aggressive measures to control animal populations on your property. Double bag garbage, and don’t leave open trash barrels sitting around. Animal foods that are stored outdoors should be kept in airtight containers. Use traps or repellents to control rodents, raccoons and squirrel populations. Resist the urge to pet stray dogs and cats. Report any sightings of feral cats to your local animal control center.

9.) Beware of ultra rich potting soil and wooden landscaping materials. Based on calls placed to our pest control operation from all over the country, springtail populations are often introduced to the home when truckloads of new mulch or soil have been dumped on properties that previously had minimal landscaping. (Mulch traps moisture and promotes the growth of mold.) Seal any cracks around basement windows before distributing natural landscaping materials around the perimeter of the home. If you’re worried about collembolla populations outdoors, there are super strength cedar oil concentrates designed to repel mosquitoes and kill insect populations in the grass and soil. Pet breeders, horse keepers, and livestock farmers use cedar oil concentrates to control all types of parasites in barns, pens and pastures. A generous treatment early in the spring or summer will do a lot to destroy eggs and control multiple insect populations before they explode. Veterinarian bills are EXPENSIVE. Destroy parasites before they destroy you!

10.) Last but not least, avoid chemical pesticides. In February of 2011, USA Today ran an article titled “Exposure to Pesticides in Womb Linked to Learning Disabilities.” The study focused on peremethrin, a chemical commonly used to battle household pests. As disturbing as this sounds, the topic is nothing new. Scores of scientific studies have linked chemical pesticides to neurological disorders, breast cancer and birth defects in children living near farms where chemicals are sprayed. In a nationally televised ABC World News investigation, spot drop flea and tick medicines were found to cause 44,000 severe reactions in a single year, including multiple deaths.

Can fish and meat textures and tastes be found in a vegetable? Chinese Black Fungus is renowned for these qualities, its vital nutrients and its valuable contributions, as a dietary supplement, to overall fitness and health. Usually obtained in dried packaged form, it requires washing before use.

As a Health Supplement

Enriching blood and preventing iron deficiency anemia, Western medical science has found Black Fungus very effective in blood viscosity modulation as it inhibits platelet aggregation thus lowering blood-viscosity levels. In Traditional Chinese Medicine (TCM) its applications include anaemia, uterine bleeding, hemorrhoids, high blood pressure and coronary heart disease. It also figures significantly in cancer prevention and relief.

A very common and inexpensive ingredient in Chinese cuisine, it also has been recognised within TCM as a medicinal food for thousands of years. Black Fungus, rich in nutrients such as iron, protein, fat, vitamins and polysaccharides, also contains vital trace elements like potassium, selenium and manganese essential to the body’s long-term health.

Black Fungus’ bittersweet taste is not particularly strong, its texture is decidedly meat-like however. Its’ presence in dishes serves rather to enhance the flavours of the main ingredients.

As a Diet Aid

Black Fungus is a potent ally in the fight against obesity. Whilst very low-calorie, its meat-like texture (and taste) when boiled make it particularly appetite satisfying. It is frequently added to other dishes to ‘enrich’ them, to bulk these up for dieting/ slimming purposes as well as for its valuable nutritional contents.

Definitely not ‘fast-food’ it needs extensive soaking and cleaning before use. Available from most Chinese supermarkets, Black Fungus is sometimes stocked by inner-city branches of Tesco.

‘Fat Busters’ to Enjoy Alongside It

Keen dieters can wash down their Black Fungus with other proven Chinese slimming, weight-loss and nutrition aids like Green Tea (Lu Cha) and Bojenmi Tea.

Green tea stimulates the heart, aids digestion and provides a general ‘wake up’ call. Encouraging fat metabolization and popular for dieting and slimming, general bodily detoxification is also encouraged by Green Tea drinking.

Anaemia sufferers (and women during their menstrual period) should avoid Green Tea as it inhibits iron-assimilation somewhat. These should switch to Bojenmi Tea (see below) and/ or consume Black Fungus to remedy iron deficiencies.

Bojenmi Cha, also known as “good health, nice appearance flesh-reducing tea” also encourages slimming and weight loss. A blend of 12 medicinal herbs based upon an ancient Ming Dynasty remedy, this pleasant tasting tea aids digestion, lowers cholesterol levels and has a mild laxative effect.

Overall

Both teas help flush out fatty deposits from internal systems. Inexpensive Green Tea’s fat removal effect’s are such that Chinese restaurants use left-overs to clean grease from tables at closing time.

Black Fungus, Green Tea and Bojenmi Tea all have internal cleansing, detoxifying and longevity-inducing effects encouraging their inclusion in anti-aging and health and fitness dietary regimes. All three can be found in most Chinese Supermarkets

 

Now that our aging population has visibly become a force to be reckoned with, many homebuilders are discovering mature adults to be a potent market. But often homebuilders tend to miss the market by focusing more on the home (which is after all what builders are selling), rather than the lifestyle (which is what drives most of the sales activity in an adult lifestyle community).

Many developers and homebuilders operate from the misconception that mature buyers prefer to live in homes that are inexpensive and focus on pricing their homes as low as possible, believing that product and price are what drives the sale. And surely there are adult lifestyle purchasers for whom price is a prime consideration. But most potential residents of an adult lifestyle community are looking for three things: adult, lifestyle and community.

Purchasers in adult communities want to be sure that the community they are considering moving to is indeed an “adult” community. As such, many such communities are age-restricted, with a hard and fast set of rules that precludes the possibility of children moving in. Of course, in jurisdictions that do not allow discrimination on the basis of age, there are other ways to “restrict” who moves in. This could range from so-called restrictive covenants registered on title of the property to rules about the permanent number of residents that may occupy any one dwelling unit (usually no more than two) under a condominium corporation or a rental agreement. Finally, the best method to maintain the integrity of an adult lifestyle community is to offer homes that are specifically designed for an older, childless demographic. The market will take care of the rest.

Some builder want to hedge their bets by offering large two storey homes in adult communities, imagining that they would be appealing to younger baby boomers that still have children at home. This fallacy results in pleasing neither the younger baby boomers that do not want to live in a community comprised largely of older people, nor the active adults seeking a childfree lifestyle.

As stated above, one of the most important considerations on the part of the purchaser in an adult community involves lifestyle. Many people in their 50s and 60s who are either retired or semi-retired have a lot of leisure time and a plethora of interests about which they are very passionate. Many are into golf in a big way and seek communities that are near golf courses. Many are into personal fitness and look for communities that provide exercise facilities. There are nearly as many interests as there are individuals seeking to live the adult lifestyle. Those communities that recognize this very important fact tend to do very well, while those that don’t, not so much.

Finally, active adults tend to be very social and seek to live in a community where they find others of similar interests and values. Many of these communities have organized activities, such as a bridge club, a golf group, round-robin tennis tournaments or group projects such as quilting or knitting. A sense of being a part of a community of like-minded individuals really is one of the most important aspects of a successful adult lifestyle community. These are the reasons why a community clubhouse is probably one of the most important amenities that any adult lifestyle community could provide. And the greater the variety of amenities and interests, the more people will be attracted to live there.

The automotive equipment industry deals with the production of every kind of tool and machinery that is needed for the manufacture, maintenance and repair of vehicles including cars and car parts. As such, the industry produces several different varieties of equipment starting from basic hand tools to more complex machinery.

Different Kinds of Automotive Equipment

Automotive workshops and garages will be unable to function without automotive equipment. Shop furniture, lifts, exhaust hoses, air compressors, lubrication equipment, electric and light reels, jacks, vehicle servicing equipment, fluid storage tanks and trans-air piping are some of the many different types of automotive equipment that are used by automotive manufacturing and automotive repair businesses.

Common Types Of Automotive Equipment

* Hand Tools: Automotive repair shops use several different types of hand tools for their repair and maintenance projects. Some of the commonest items include ratchet sets and wrench sets, crowbars (also known as pry bars), socket sets, screwdrivers, star and clutch-head drivers, hammers, pliers and wire cutters, electric drills, hacksaws and torque wrenches.

* Pneumatic Tools: Most automotive workshops now use pneumatic tools as an alternative to electricity powered motors because the latter is more prone to fire hazards. Such tools are powered by compressed air and are high powered versions of the more traditional hand tools. Common examples of pneumatic automotive equipment include air compressors that can be used to power a variety of tools including hammers, drills, ratchets and spraying tools.

* Availability of pneumatic equipment makes it easier for mechanics and technicians to undertake repair and maintenance work because they are powerful and easy to use. For example, a set of pneumatic shears can cut through sheet metal at a faster rate and leave behind a smoother edge when compared to traditional tin snips. Similarly, air hammers outfitted with chisel or punch bits have multiple uses. They can they be used for straightening dents. The chisel feature can be used to break rusted parts loose and the punch bits can be used to remove old rivets and bolts that are too difficult to take out by hand.

* Lifts: several different kinds of lifting equipment are used to lift and secure cars so that mechanics and repair persons can easily work under the vehicle. These lifting tools include both low-tech tools such as basic floor jacks, car ramps and jack stands as well as hydraulic lifts and floor jacks for better efficiency and performance.

* Vehicle Exhaust Removal Systems: vehicle exhaust removal systems are used to capture and remove harmful exhaust fumes to insure optimal air quality in automotive maintenance and repair facilities. These are mandatory equipment as per OSHA Standards in order to limit exposure to harmful vehicular emissions. Common vehicle exhaust removal systems include hose drops as well as reels.

* Lubrication Systems: Automotive lubrication systems include several different types of oil meters, ATF meters, gear lube meters, dispense valves and grease dispenses valves.

The Automotive equipment business is a very large and competitive business. Automotive repair businesses must buy equipment from reputable dealers for the best deals and performance levels.

Bhumihar caste includes the Brahmins. They are known as Bhumihar Brahmins. When the girl in their family reaches the age of wedding, they plan things. The search for the partner begins. If its an arranged wedding then the bride and the groom get married within the same caste. They get a chance to talk to each other and when they like each other, the talks are taken a step forward. In Bhumihar matrimony, you will see that the weddings have a lot of customs and rituals. Yes, they are quite interesting but they go on for a few days. Thus, when there is a wedding at home, you will see a few pre-wedding ceremonies too.

The pre-wedding ceremonies

In Bhumihar weddings, you will find a number of pre-wedding rituals. They are:

    • There is a tradition called as Siddhanth custom. In this, the priest sits and looks into the panchang to fix the wedding date. Also, he has to see panjis of both the families. These people also believe in horoscopes and that plays a key role in these weddings.

 

    • There is one more different and strange custom. A day before the wedding or the day of a wedding, you will see that the bride has to take blessings of a washer man’s wife. This is because it is believed that a washer man’s wife will always die before her husband and thus she would always remain suhagan.

 

    • On the day of the wedding, when the groom enters the wedding premises, the girl from the bride family would welcome him with sandalwood paste.

 

    • In this, the couple has to then go for the kul devi shrine. The bride’s father takes them. Thus, the groom would get a chance to seethe kul devi mandir of the bride’s father.

 

  • Gauri puja is also quite important as a part of Bhumihar matrimony. This is mainly performed to keep the evils away from the wedding ceremony.

Thus, you will find that there are some really interesting rituals as seen in Bhumihar weddings too. You will really find these rituals quite meaningful. Bhumihar is simple people. But they are quite strict about the wedding and the wedding rituals.

In the times when the younger generation is moving away from rituals, the younger generation of Bhumihar caste is still quite interested in the wedding in an authentic and traditional way. That’s the charm of Indian weddings. Just like other weddings, there is fun too involved in the wedding. Of course, you will also be able to find food and tasty food served to the guests in an authentic way. You should understand that wedding is the time when two families would unite. Thus, it is really an important ceremony. Thus, all the functions and events should be carried out properly. Bhumihar is simple Brahmins. But they are knowledgeable and educated. The bride and the groom are also well brought up and they know the relevance of culture and ethics too. That’s the reason why you can find these weddings more traditional.

The KWP2000 protocol has become a de facto standard in automotive diagnostic applications. It is standardized as ISO 14230-3. KWP2000 describes the implementation of various diagnostic services you can accethrough the protocol. You can run KWP2000 on several transport layers such as K-line (serial) or CAN.

Transport Protocol

As KWP2000 uses messages of variable byte lengths, a transport protocol is necessary on layers with only a well defined (short) message length, such as CAN. The transport protocol splits a long KWP2000 message into pieces that can be transferred over the network and reassembles those pieces to recover the original message.

KWP2000 runs on CAN on various transport protocols such as ISO TP (ISO 15765-2), TP 1.6, TP 2. 0 (Volkswagen), and SAE J1939-21. For KWP2000, the Automotive Diagnostic Command Set supports only the ISO TP (standardized in ISO 15765-2) and manufacturer-specific VW TP 2.0 transport protocols.

Diagnostic Services

The diagnostic services available in KWP2000 are grouped in functional units and identified by a one-byte code (ServiceId). The standard does not define all codes; for some codes, the standard refers to other SAE or ISO standards, and some are reserved for manufacturer-specific extensions. The Automotive Diagnostic Command Set supports the following services:

• Diagnostic Management

• Data Transmission

• Stored Data Transmission (Diagnostic Trouble Codes)

• Input/Output Control

• Remote Activation of Routine

Upload/Download and Extended services are not part of the Automotive Diagnostic Command Set.

Diagnostic Service Format

Diagnostic services have a common message format. Each service defines a Request Message, Positive Response Message, and Negative Response Message. The Request Message has the ServiceId as first byte, plus additional service-defined parameters. The Positive Response Message has an echo of the ServiceId with bit 6 set as first byte, plus the service-defined response parameters.

The Negative Response Message is usually a three-byte message: it has the Negative Response ServiceId as first byte, an echo of the original ServiceId as second byte, and a ResponseCode as third byte. The only exception to this format is the negative response to an EscapeCode service; here, the third byte is an echo of the user-defined service code, and the fourth byte is the ResponseCode. The KWP2000 standard partly defines the ResponseCodes, but there is room left for manufacturer-specific extensions. For some of the ResponseCodes, KWP2000 defines an error handling procedure. Because both positive and negative responses have an echo of the requested service, you can always assign the responses to their corresponding request.

Connect/Disconnect

KWP2000 expects a diagnostic session to be started with StartDiagnosticSession and terminated with StopDiagnosticSession. However, StartDiagnosticSession has a DiagnosticMode parameter that determines the diagnostic session type. Depending on this type, the ECU may or may not support other diagnostic services, or operate in a restricted mode where not all ECU functions are available. The DiagnosticMode parameter values are manufacturer specific and not defined in the standard. For a diagnostic session to remain active, it must execute the TesterPresent service periodically if no other service is executed. If the TesterPresent service is missing for a certain period of time, the diagnostic session is terminated, and the ECU returns to normal operation mode.

GetSeed/Unlock

A GetSeed/Unlock mechanism may protect some diagnostic services. However, the applicable services are left to the manufacturer and not defined by the standard.You can execute the GetSeed/Unlock mechanism through the SecurityAccess service. This defines several levels of security, but the manufacturer assigns these levels to certain services.

Read/Write Memory

Use the Read/WriteMemoryByAddress services to upload/download data to certain memory addresses on an ECU. The address is a three-byte quantity in KWP2000 and a five-byte quantity (four-byte address and one-byte extension) in the calibration protocols. The Upload/Download functional unit services are highly manufacturer specific and not well defined in the standard, so they are not a good way to provide a general upload/download mechanism.

Measurements

Use the ReadDataByLocal/CommonIdentifier services to access ECU data in a way similar to a DAQ list. A Local/CommonIdentifier describes a list of ECU quantities that are then transferred from the ECU to the tester. The transfer can be either single value or periodic, with a slow, medium, or fast transfer rate. The transfer rates are manufacturer specific; you can use the SetDataRates service to set them, but this setting is manufacturer specific. The Automotive Diagnostic Command Set supports single-point measurements.

Diagnostic Trouble Codes

A major diagnostic feature is the readout of Diagnostic Trouble Codes (DTCs). KWP2000 defines several services that access DTCs based on their group or status.

Input/Output Control

KWP2000 defines services to modify internal or external ECU signals. One example is redirecting ECU sensor inputs to stimulated signals. The control parameters of these commands are manufacturer specific and not defined in the standard.

Remote Activation of a Routine

These services are similar to the ActionService and DiagService functions of CCP. You can invoke an ECU internal routine identified by a Local/CommonIdentifier or a memory address. Contrary to the CCP case, execution of this routine can be asynchronous; that is, there are separate Start, Stop, and RequestResult services. The control parameters of these commands are manufacturer specific and not defined in the standard.
