electronics Car – History written in her car

14/09/2019 A young man 0 Technique,

In modern cars electronics is responsible for controlling almost all relevant elements. thanks to her, we are able to perform electronic diagnostics car and get to know a lot of facts from the history of the car – including actual mileage.

In the past, automotive electronics was limited to management systems injection and ABS. Along with technological development, started with the addition of electronic controls and management to work more and more elements of equipment of cars, na primer, manage lights, suspension or even a diffuser air in the cabin. This happened after the popularization of CAN bus that. system that allows the transfer of data between components of a car.

Thanks to the invention, opened up new possibilities in the automotive diagnostics. A number of sensors connected to each other analyze a multitude of key data for the current operation of individual systems and their maintenance or repair. na primer – the brake controller notifies the number of the brake pedal, and an air bag controller keeps track of critical errors together with past kilometers.

Progress automotive electronics has forced many workshops to purchase new equipment and train employees. In turn, users has opened up new opportunities for verification of the history of the car. In fact, anyone who is interested in a used car is afraid that his meter may "turn back". Scam negligent agent usually comes to the knowledge immediately after a thorough review of the car by an experienced technician, but it is not necessary to work in an authorized service center. It must be recognized, however, that in the case of professional “corrections” mileage, or correction of the data contained in the modules, this unfair practice is still difficult to detect.

Provera actual mileage used car is just one of the advantages that can give a detailed review of automotive electronics. Below are examples of actions that can be executed on the electronics the most popular car brands. Caution! Ovo su only aggregated examples; able detailed scanning cars, depending on the model, and often also on the engine versions.

DSC mode: shows the parameters relating to the stability control system, ie. mileage at which a DSC system activated last, the speed at that time, and even the brake fluid level;
master cylinder: allows you to specify the actual mileage in two ways. first – based on the number of the brake pedal (assuming for 1 km pedal is depressed 1,5-2 times, car was 300 000 km should have 600 000 the pedal stroke). other – based on the pump operating time (based on the average speed);
SMG transmission (automated): thanks to the diagnosis we'll find out how long the car is driven in a sporty mode;
additional modules: you can program, among other things the speed, after that will automatically close doors, light daytime running lights and turn ignition on or off the lights when the car close.

other opportunities for BMW car electronics:

check the date of manufacture of modules;
Access to operating parameters of components, eg. voltage battery, Coolant temperature, exact speed and the engine run time.

conclusion

Working diagnosis cars with experienced service technician if the dishonest seller has not changed the parameters of the key modules. We'll learn the most facts from the history of electronics French and German cars; Japanese and niche brands (like Saab) have limited room.

The increasing complexity of electronic means in modern, especially luxury cars, all the weight back hard counter. There are companies that deal with time, correcting memory almost all modules. Unfortunately, even vendors who cut mileage by simple methods do not account for problems, because many buyers do not check the vehicle.
