Component Location
General Description

Alternator output and power demand of all electrical loads and systems must be matched to each other as ideally as possible so that the entire system is reliable and trouble-free in operation. The ECM monitors alternator output deviation from the signal of the FR terminal of the alternator when the engine is running.

DTC Description

ECM sets DTC P0625 if the ECM detects that the alternator’s output duty signal is 100%.
