Was bedeutet der Fehlercode?

When the engine is started, the ECM sends a signal to the starter relay that controls the starter motor. The code is set when the module finds that the signal is faulty and that the voltage in the circuit is too low. The fault may be a signal wire shorted to ground or with a break, poor connections, or an internal fault in the module.

Mögliche Ursachen

Signal wire shorted to ground
Contact resistance, oxidation or break in connections
Break in the signal wire
Internal fault in the ECM

Was Sie tun können

1Check that the fuses are intact
2Check the signal wire from the engine control module to the starter relay for breaks, chafing and loose connections
3Use a multimeter to check that the signal wire has no contact with ground and no break
4If you have a diagnostic tool, read the relevant start signals in live data during starting attempts and see whether they follow the attempt
5Clear the code and try to start the engine to see whether the code returns
6If the code returns, have a workshop with diagnostic equipment check the engine control module, as an internal fault may be the cause

Symptome, die Sie bemerken können1

The engine does not start, either sometimes or always
