BCM-0022

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.
- BCM-0012: Wheel sensor, left front
- BCM-0022: Wheel sensor, right front
- BCM-0032: Wheel sensor, left rear
- BCM-0042: Wheel sensor, right rear.
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, see Brake system abbreviations.

Possible source
- Loose wheel sensor
- Damaged wiring
- Defective pulse wheel.

Fault symptom[s]
- The ABS warning lamp is lit
- The anti-spin warning lamp is lit (up to and including 2002 model year)
- General warning lamp lit
- No ABS function
- Anti-spin does not function
- The traction control system does not function.

Note: If the fault becomes intermittent, the ABS warning lamp will not go out until the vehicle speed exceeds 10 km/h in the next operating cycle.
