Checking engine speed signal

Note!

The signal generated by engine speed sender -G28- is processed by the engine control unit and transmitted via contact 22 of the engine control unit to various electronic systems (e.g. the air conditioner control unit and ABS/EDL control unit). The engine speed signal and wiring are monitored by these systems.
