The cars considered in the given Management, are equipped with several systems of decrease in toxicity of the fulfilled gases. Concrete execution of system of protection of environment is defined by mark of the car and territory of its sale. The specified systems concern:

 – System of compulsory ventilation картера (PCV-system),
 – System of catching of steams of gasoline (EЕС-система),
 – System recycling the fulfilled gases (EGR-system),
 – каталитический neutralizer (TWC),
 – пульсационная system доокисления exhaust gases (PAIR-system).
 – Onboard system diagnostics (OBDII-system).

The concrete kind of systems with instructions of the adjusting data and distributings of vacuum hoses is specified on подкапотной to the tablet (VECI-tablet).

Refusal of gauges and devices of some systems of decrease in toxicity can affect operational characteristics of the engine. Reading of diagnostic codes and an exact establishment of the concrete faulty device is possible thanks to application on the car of system of onboard diagnostics OBDII (since 1996). For reading in this system of diagnostic codes of malfunction and their identification the special expensive scanners, therefore all kinds of works on diagnostics are required, it is expedient to repair and adjustment to carry out in car-care centre.
