BCM-0022

BCM-0022: Wheel Sensor, Right Front, Faulty Signal Condition





The Brake Control Module (BCM) receives information about the wheel speed for each wheel. The wheel sensors, which are on the wheel mounting, read off a pulse wheel on the wheel spindle. Diagnostic Trouble Code (DTC) BCM-0012, BCM-0022, BCM-0032 or BCM-0042 is stored, depending on the wheel sensor, if the control module registers that the signal from the wheel sensor is distorted or missing too many times.

The diagnostic Trouble Code (DTC) can be diagnosed at speeds above 10 km/h.

Substitute value
- The ABS is blocked
- Traction control is blocked
- Stability control is blocked
- Active yaw control is blocked
- Brake assistance is blocked
- Electronic Brake Force Distribution (EBD) is blocked if two or more wheel sensors are not working.

Hint: For information about abbreviations, Refer to Description and Operation.

Possible source
- Loose wheel sensor
