P0625Generator Field/F Terminal Circuit Low

The computer saw too low a voltage on the alternator's field (F) terminal control circuit. The field circuit controls how strongly the alternator charges. A low signal here usually points to a wiring fault or a problem inside the alternator.

Ամենատարածված պատճառներն են՝ Short to ground or open in the field/F terminal wiring, Corroded or loose connectors at the alternator or ECM, Faulty alternator or internal voltage regulator, Poor ground connection, Failed ECM control circuit (less common)։

Սովորաբար անվտանգ է կարճ տարածությունների վրա վարել, սակայն շուտով ստուգել տվեք։

Get the charging system and the alternator field wiring inspected soon to avoid a dead battery. A technician will measure voltage at the F terminal and check the alternator and wiring. Short trips are usually fine, but if the battery light comes on or lights dim, stop driving and have it checked.
