Component Location

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

If the alternator's output duty signal is over 50% under IG ON (Engine speed is below 20 rpm.), ECM sets P0625.
