Was bedeutet der Fehlercode?

The rear electronic module (REM) monitors the power feed to the rear fog lamp through the trailer connector. The code is set when the output is shorted to supply voltage or when the driver stage becomes too hot. The fault can show up as the fog lamp staying on all the time or not working at all.

Mögliche Ursachen

Short circuit to supply voltage in the signal wire
Internal fault in the rear electronic module (REM)

Was Sie tun können

1Note any other fault codes before clearing the codes, so they can be used in further fault tracing
2Check the connectors and wiring in the trailer connector and between the rear electronic module and the trailer module for looseness and corrosion
3Switch the rear fog lamp on and off and listen for a click from the relay; a click means the wiring up to the module is probably fine
4Use a multimeter to check whether the supply wire to the fog lamp has voltage when the lamp is off; if it does, have a workshop trace the fault further

Symptome, die Sie bemerken können2

The rear fog lamp stays on all the time
The rear fog lamp does not work

Was der Fehler beeinflussen kann2

The control module switches off the output to the fog lamp
On cars built from late September 2005 the output is shut off permanently if the fault has been present over many ignition cycles in a row, until the code is cleared
