What does this fault code mean?
The all-wheel drive control module (DEM) sends a signal stating that its information is faulty, and the brake control module (BCM) then sets the code. The fault lies in the all-wheel drive module, not in the brake module. The stability functions and cruise control may be affected for as long as the fault remains.
Possible causes
- Fault in the all-wheel drive control module (DEM)
What you can do
- 1Read codes in the all-wheel drive control module and troubleshoot them according to the accompanying information
- 2Do not replace the brake control module for this code, as the fault lies in the all-wheel drive module
- 3Clear the code only once the fault has been corrected, and check that it does not return
- 4The brake and stability systems are safety-critical, so have a workshop carry out any work on the all-wheel drive system and the brake control module
Symptoms you may notice5
- Traction and anti-skid warning lamp lit
- Stability function does not work
- Traction control does not work
- Anti-skid function does not work
- Adaptive cruise control does not work
What the fault can affect2
- Stability control and traction control are disabled
- Dynamic stability control (AYC) is disabled
