Was bedeutet der Fehlercode?
The four-wheel drive control module (DEM) receives a message from the engine control module (ECM) that the information it sends is incorrect. The code is event-controlled, meaning it is information that something has occurred rather than a fault in the DEM. It is a follow-on code: the root fault lies in the engine control module and should be remedied first, after which this code can be cleared. Four-wheel drive then works with reduced function.
Mögliche Ursachen
- Fault in the engine control module (ECM), which sends out invalid information
Was Sie tun können
- 1Read off the fault codes in the engine control module and in the central electronic module (CEM) and remedy them first, since this code is a follow-on fault
- 2If you have a diagnostic tool, read the engine data in live data with the engine running and check that the engine speed is displayed steadily
- 3Check that the fuses are intact and that the battery is in good condition
- 4Clear this code only once the root fault in the engine control module has been remedied, then test drive the vehicle
- 5If the fault remains after the root fault has been remedied, have a workshop investigate the engine control module and the CAN network
Symptome, die Sie bemerken können1
- Four-wheel drive does not work
Was der Fehler beeinflussen kann1
- Four-wheel drive has reduced function
