Was bedeutet der Fehlercode?

The engine control module (ECM) requests a fan speed from the electric fan control module, which varies the voltage to the fan motor steplessly. The code is set when the fan speed is too low. The fault may be an internal fault in the fan control module, a signal wire shorted to supply voltage or a damaged fan control module.

Mögliche Ursachen

Internal fault in the electric fan control module
The signal wire is short-circuited to supply voltage
Damaged electric fan control module

Was Sie tun können

1Check that the fuses for the electric fan are intact. Their location is given in the owner's manual or on the fuse box cover
2Look for chafing or pinch damage on the signal wire to the electric fan control module, where it may have touched supply voltage
3Use a multimeter to check that the signal wire is not short-circuited to supply voltage
4If you have a diagnostic tool, read the fault status with the engine running and see whether the fault is still active
5If the fault remains, have a workshop check or replace the electric fan control module
6After repair, check that the fault status shows no fault once the diagnosis is complete

Symptome, die Sie bemerken können3

The engine overheats or runs hot
