Hva betyr feilkoden?

CEM picks up a high signal on the status flag when the relay control for the daytime running lamp is activated. The fault code is set because the control to the relay is short-circuited to battery voltage, and the front lighting then does not work.

Mulige årsaker

Relay control for the daytime running lamp relay short-circuited to battery voltage

Hva du kan gjøre

1Switch the ignition off and check the daytime running lamp relay, making sure it is seated and its contacts are not corroded
2Use a multimeter to check that the wire to the relay control has no contact with battery voltage
3Remedy what is found and clear the fault code
4If no fault is found, try a new relay
