VOLVOUU Engine D13F Fault Code: SID 4 FMI 5 Injector #4

CONTROL UNIT:
Engine ECU

DETECTION CONDITIONS:
The engine control unit (E-ECU) registers current too low.

SYMPTOM:
1. Low power.
2. Engine runs rough/varying engine speed.
3. 3- or 5-cylinder operation.

POSSIBLE CAUSES:
1. Short circuit to lower voltage on injector’s low voltage side.
2. Short-circuit to higher- or lower-voltage on injector’s high voltage side.
3. Open circuit on injector’s high voltage side.
