Diagnostic trouble code (DTC) information
Condition
The diagnostic trouble code (DTC) applies only to cars with all-wheel drive (AWD) and dynamic stability and traction control (DSTC).
The differential electronic module (DEM) indicates to the brake control module (BCM) when four wheel drive is activated. During four wheel drive the brake control module (BCM) must not activate the stability function due to the risk of disrupting the differential electronic module (DEM). A DTC is stored if the Brake control module (BCM) registers that the difference in speed between the front and rear wheels is too great.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.
Substitute Value
- Stability control is blocked
- Active yaw control is blocked.
HINT: Brake system, abbreviations
Possible Source
- Damaged Differential Electronic Module (DEM).
This diagnostic trouble code (DTC) is not due to an internal hardware fault in the Brake control module (BCM) and must not be remedied by replacing the control module.
Fault symptom[s]
- The anti-spin warning lamp is lit (up to and including 2002 model year)
- General yellow warning lamp lit (from model year 2003 inclusive)
- Anti-spin does not function
- The stability control system does not function.
