Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-0094

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. The brake control module (BCM) requests the opening of the coupling for four wheel drive so that it can calculate the reference speed of the car. The diagnostic trouble code (DTC) is stored if the brake control module (BCM) registers that the signal from the differential electronic module (DEM) is missing.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute value
- Stability Control is blocked
- Traction Control is blocked
- Active yaw control is blocked.

- Internal fault in the differential electronic module (DEM).

Fault symptom[s]
