Check and adjustment of a corner of an advancing of ignition
As the corner of an advancing of ignition is constantly controlled and regulated by a control system of the engine, the nominal rate does not exist. Check and manual adjustment is impossible.
The corner can be checked by means of the special equipment attached to the diagnostic socket of a control system of the engine (drive away the car on HUNDRED Mercedes-Benzs).
Adjustment is impossible.
If the corner is established incorrectly, the control system of the engine is faulty.
