Was bedeutet der Fehlercode?

The rear electronic module (REM) has registered that its supply voltage is lower than the supply voltage to the central electronic module (CEM), which points to a voltage drop in the supply. The fault is intermittent, meaning it has occurred before but may no longer be present. Because the REM controls several functions at the back of the car, these can be affected.

Mögliche Ursachen

Open circuit or short circuit to ground in the supply to the rear electronic module (REM)
Contact resistance, oxidation or loose contact in the supply to the rear electronic module (REM)

Was Sie tun können

1Read the fault code, clear it and test drive the car to see whether it returns
2Check the wiring and connectors in the supply to the rear electronic module (REM) for chafing, loose contacts and corrosion
3Use a multimeter to check that the supply wire to the rear electronic module is not shorted to ground (the body) and has continuity all the way
4If the fault returns after these checks, have a workshop trace the supply further
