Self directed: to select devices for a computer diagnostic

More recently, computer-aided diagnosis was performed only in dealership service centers with the involvement of expensive professional equipment and specially trained personnel. And today, every car enthusiast can buy quite a affordable equipment and to monitor the health of the machine. There are devices with different functions — you can choose the right, there is a corresponding knowledge of the user and his needs.

Dealer diagnostic equipment (software and adapters) release, not the automakers themselves, but by specialized companies. In some cases they supply their products to the market and even offer more simple and low-cost solution for ordinary consumers. However, the absolute most Amateur devices — assorted copies of the dealer of equipment from cheap likes with very limited functionality to good-quality clones.

Goals and means

The simple K‑Line interface adapter is used to diagnose cars that do not have a data bus CAN. A similar set of “lace” and the VAG-COM to work with Volkswagen models (1990-2004) issue costs about 1500 rubles.The simple K‑Line interface adapter is used to diagnose cars that do not have a data bus CAN.

Diagnostic equipment is software and car adapter (scanner), which, in fact, is a separate unit with one or more chips. It is a means of communication between the vehicle and diagnostic software installed on any laptop, tablet or even smartphone. Devices for self-diagnosis are divided into three groups. The higher the requirements of the buyer, the more Amateur the device repeats the hardware and software of the dealer of the product and the more expensive it is.

Minimum capabilities give simple Chinese universal adapters. To work with suitable laptop or mobile device and application to diagnose via the OBD connector, which can be downloaded from the Internet. Using these adapters can read and decipher errors on many machines, and to control the operating parameters of vehicle systems in real-time (e.g., sensor readings). Bright representatives of this group — wireless adapter ELM 327 and applications such as Torgue and DashCommand.

The second group advanced universal devices. For example, in this niche plays a firm Launch, which in the past produced a rich assortment of the dealer equipment. Its eponymous product is from its own adapter (it is more advanced than the ELM) program. In addition, will have to pay extra for functionality (optional software package) corresponding to the marches of the chosen car. Buying the original product, the consumer gets a warranty and updates.

Right — yellow multibrand adapter Launch tied with the same software. This is an original equipment brand with a reputation is an average of 5,000 rubles. The difference in price due to more features and convenience.The left — popular universal adapter iCar (ELM 327) price of about 2000 rubles.

This is an original equipment brand with a reputation is an average of 5,000 rubles. The difference in price due to more features and convenience.

The feature of the Launch equipment — the two types of adapters. Yellow has the same diagnostic features as the ELM, however, he is not saved at work and will allow you to control much more parameters. The red adapter is more expensive, it allows you to use different service modes, such as embedding an electric caliper when replacing the pads. Of course, the market already has a hacked version of the program for all models and yellow adapters, modified to the level red.

The third group — equipment for diagnostics of cars of a certain brand or group, which has the potential dealer equipment. Such devices have many additional important options: reset and installation service intervals, testing of actuators and a change in their mode of operation (adaptation); the coding of control units (disabling or activating). With this equipment it is possible to reflash the various control modules, or activate options are disabled on the machines for our market (for example, auto lowering mirrors in reverse gear of course), or to carry out reconfiguration (for example, to change the mode of operation of the headlamp washer). With such programs, and their interface is not enough without a laptop.

However, equipment with such wide possibilities is fraught with serious dangers. It is often in appearance can determine how well made the device and what software used. For example, the original adapter has two boards, and the underground Chinese manufacturers manage to limit it to one. Blemishes left software is unlikely to emerge when reading errors or control parameters. And if reprogramming of any of the units or adapting automatic gearbox is a simple and cheap version of the original device can pass, and make mischief: kill module or to drive the transmission in emergency mode. Not to be in such a situation, follow the appropriate Internet forums, or contact the companies specializing in the sale of diagnostic devices. They tell us that is capable of this or other equipment.

To the right is a cheaper Chinese substitute: looks more attractive but is much easier and will cost 4000 rubles. The reason is simple: there is no second card, whereby the device’s capabilities are limited.On the left — clone adapter dealer to diagnose cars of concern Volkswagen.

Among the popular and quality sets belonging to the third group, I note BMW Rheingold and VCDS (for cars of concern Volkswagen). The first player is an advanced adapter with the well-hacked dealer program. He far exceeds all the needs of the average user. VCDS works with its own software (VAG-COM) and has more modest capabilities than Rheingold, but it is enough for the Amateur level and the most important manipulation of the car.

There are on the market and full clones dealer equipment with the appropriate capabilities and price tag. But such devices are unlikely to purchase privately owned. It’s funny that diagnosticians, even with such equipment, often resort to naborchiki from the third level to do all sorts of things — for example, to reset the counter degradation of the oil or service interval. Dealership clones, sharpened, enhanced diagnostics, are too serious to even minor manipulations, making a lot of extra checks.

Intermediaries and bonuses

The selection of equipment plays a decisive role car brand, model and generation, and user requirements to the capabilities of the devices. One can study the relevant Internet forums and to buy a suitable adapter and software. An inexperienced person will take a long time to understand all the nuances and to acquire adequate working set that would satisfy his needs. But in this case it is possible to save money by buying products in the online store of AliExpress.

The second option is to use the services of specialized firms involved in the spread of popular equipment. The price may be two to three times higher, but there are additional bonuses. Such companies offer ready-made and proven solutions for a particular car and the owner’s request. In this case, the buyer is immune from faulty and substandard equipment (like swarms) that will refuse to work on the car. In an extreme case, the components of the broken set for free exchange. These companies often are engaged in manufacturing of adapters and distributing the software and, if necessary, provide technical support, learn to use the equipment. In addition, the owner receives free updates of the software.

The average Amateur equipment is 3000-5000 rubles. Its capabilities cover the basic needs of car owners. More serious sets will cost 10 000 rubles. Such is fine for experienced users who know a lot about the diagnosis and want to do it for yourself. For comparison, the cloned professional level equipment for service costs 40 000-60 000.

Even the simplest kits are able to read and decipher mistakes, and you will be able at least to understand about what happened with the car and whether it will lead to serious damage. Sometimes even that superficial information is sufficient to make a diagnosis. The bigger sets will help to understand in more complex tasks. For example, advanced owners of some models of Volkswagen have long since learned to control the condition of the timing chain according to the divergence angles of the valve timing on the shafts. It helps in time to prevent open circuit and therefore to avoid costly engine repair.

One of the advantages of the program is the availability of electrical circuits. Other brands they are on a separate portal, which still need to access.Dealer diagnostic program BMW Rheingold is one example of a good and inexpensive product.

More expensive, but available equipment if you have experience and skills allows you to completely abandon the service station, unless, of course, will not have the specific breakdown with conflicting symptoms, which will deal only a professional diagnostician.

In addition, the owner can very quickly heal your car a fresh firmware of the control units activate the hidden beneficial functions to reconfigure existing or to make timely adaptation of the robotic box, as its wear — to prolong the service life.

Buying equipment for self-diagnosis, you need to remember an important rule: it is not a panacea for all ills. And man no king in his head, armed with such devices, may be mangled a lot of firewood. But with proper use of diagnostic equipment improves the level of control over the condition of the vehicle and allows you to save time and money.
