Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

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 Brake System, Abbreviations.

Possible source
- Loose wheel sensor
- Damaged wiring
- Defective pulse wheel.
- Dirt between wheel sensor and pulse wheel.

Note! 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 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.
