Co oznacza ten kod błędu?
The code concerns valve 2 in the cooling circuit for the drive components of the hybrid. It is set when the signal wire to the valve is shorted or has an open circuit, and the engine control module (ECM) monitors the valve all the time. If the valve does not work, cooling of the drive components may stop.
Możliwe przyczyny
