2.5.3.15. Neutral switch

Malfunction of an entrance of the switch of a neutral (P0850)

The PCM block controls changes entrance neutral switch tension. If the PCM block does not find on a conclusion 1W of the PCM block of change of tension at the movement of the vehicle with a speed more than 30 km/h and repeated (10 times) pressing a coupling pedal, then he decides that the chain of the switch of a neutral has malfunction.
