Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition

Note! 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 signal from the Differential electronic module (DEM) is missing, or if the signal indicates that four wheel drive is not working.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute value
- Stability control is blocked
- Traction control is blocked (All-wheel drive (AWD) TRACS (Traction Control System) is blocked without a warning lamp lighting)
- Active yaw control is blocked.

Hint: Brake system, abbreviations Brake System, Abbreviations

Possible source
- Open-circuit or short-circuit in the wiring for the control area network (CAN)
- Damaged Differential Electronic Module (DEM).

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
- The traction control system does not function.
