Note: The first check is made after 3 years of operation.
The check consists in testing the engine management system using a special device connected to the diagnostic connector (see chapter 5). In the process of diagnostics from the memory of the electronic engine control module (ECM) fault codes are read. Due to the need to use special expensive equipment, this kind of diagnostics is carried out in a service station. The composition of exhaust gases is monitored using a special gas analyzer and is usually included in the number of regular checks carried out when the car passes the state inspection. If desired, this check can be carried out at most service stations.
