Modern cars are increasingly equipped with control and diagnostic equipment. These methods are used to optimize the working process in the engine, improve traffic safety and simplify operation and maintenance.
You can adjust the chip to your liking, adjust the "performance" of the engine, because comfortable driving conditions give us a lot of pleasure.
The current control of technical conditions is carried out by the onboard system of self-diagnostics, which is an integral part of the controller. Problems that occur are signaled visually and stored in electronic memory. The full list of actual settings of codes of self-diagnostics and parameters of working process is carried out on HUNDRED with automobile indicators of brand. The problem is determined only by connecting a tester or scanner to a special diagnostic connector available in the car.
However, there are often complaints about objective and comprehensive examinations.
Misdiagnosis of "standards" with obvious signs of external problems is often given for many reasons. First of all, the use of information is limited electrical signals. In fact, the state of the circuit of sensors and actuators of engine automation is determined. Degradation of complex structures is usually based on the "domino principle": one local problem leads to another, another to a third, etc., which leads to the complete failure of the whole device. Problems with electricity may not be the cause but the consequences of other problems, including non-electrical causes. For example, the "ringing" of the piston fingers may indicate early inflammation and wear of the relevant components. The instability of the spark discharge in the spark plug may be the result of decompression of the working volume of the cylinder or improper preparation of the working mixture. The problem of the intake manifold or contamination of the fuel injector is usually recognized by the self-diagnostic system as a fault of the lambda detector. The list of such ambiguities can be expanded. When it is necessary to "restore" the accident of "decent age", branded diagnostic equipment may be useless.
