Check and adjustment of a corner of an advancing of ignition

As the corner of an advancing of ignition is constantly supervised 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 (address to the Section Self-diagnostics of systems of electronic control of the second generation of OBD II). Adjustment is impossible. If a corner the control system of the engine is established incorrectly, faulty.
