Was bedeutet der Fehlercode?

The engine control module has recorded a fault in the system relay, which switches off the main relay after the ignition is turned off. The fault is intermittent, meaning it comes and goes, and may not be present right now. The code normally causes no noticeable symptoms for the driver.

Mögliche Ursachen

The main relay is faulty
The signal wire is shorted to earth

Was Sie tun können

1Check the wires and connectors to the system relay for play, chafing and corrosion
2Listen when the ignition is switched off: the main relay should switch off at the right time. If you hear nothing or notice anything unusual, make a note of it
3Measure with a multimeter that the signal wire to the relay is not shorted to earth
4Clear the fault code and road test the car. If it returns, have a workshop investigate the system relay and the main relay
