Was bedeutet der Fehlercode?

The code means that the signal from one of the temperature sensors in the electric rear axle (ERAD) is too high. This may be caused by the signal cable being short-circuited to supply voltage or by a break in the cable. The control module (IEM) sets the code when the reading from the sensor falls outside the normal range. The performance of the rear axle is then reduced.

Mögliche Ursachen

Loose contacts, contact resistance or oxidation at the joints between the ERAD and the voltage converter (ISC)
Signal cable short-circuited to supply voltage
Open circuit in the signal cable
Damaged wiring between the ERAD and the ISC
Damaged temperature sensor in the ERAD
Internal fault in the voltage converter (ISC)

Was Sie tun können

1If you have a diagnostic tool: read the temperature values from the electric rear axle in live data and see whether one sensor reads abnormally high compared with the other
2Have a workshop check the temperature sensor's signal cable for a short to supply voltage and for a break. High voltage systems may only be handled by qualified personnel
3Do not carry out any measurements or work on the high voltage wiring yourself
4After the repair, read out the fault codes and check that the code is not stored again

Symptome, die Sie bemerken können4
