Was bedeutet der Fehlercode?
The ECM monitors the starter motor relay signal that runs through its ground wire. The code is set if the signal is missing or faulty. The check only starts after the engine has been started, so the fault can only be detected once the engine is running and the conditions are met. The cause may be an open circuit in the ground wire between the control module and the starter relay, or an internal fault in the relay.
Mögliche Ursachen
- Open circuit in the ground wire between the engine control module (ECM) and the starter relay
- Internal fault in the starter relay
Was Sie tun können
- 1Read the code, clear it and road test the car to see whether it comes back
- 2With the ignition off, check the connections and wiring between the control module and the starter relay for breaks and loose fit
- 3Use a multimeter to check that the ground wire to the starter relay has no break to the body
- 4Check that the starter relay is firmly seated and that its contacts are free from oxidation
- 5If the fault remains after these checks, have a workshop try a new starter relay
Symptome, die Sie bemerken können1
- The starter motor does not operate
