BCM-C003A64 - Right Rear Wheel Speed Sensor. Algorithm Based Failures. Signal plausibility failure
System
Brake Control Module (BCM)
Volvo models this fault code applies to
Applies to the following models:
1 modelV60 (2011–)
Show models by year and engine (2)
What does this fault code mean?
On the V60, the brake control module (BCM) has received too high a signal from the right rear wheel sensor and judges it to be implausible. The module compares the signal with the other wheels and sees that it deviates in a way that does not match the wheel's actual movement. The fault most often lies in the wiring or the sensor.
Possible causes
- Damaged wiring to the right rear wheel sensor
- Damaged right rear wheel sensor
What you can do
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Look for damage in the wiring to the right rear wheel sensor, particularly in the wheel arch
- 3Check that the right rear wheel sensor is undamaged and secure
- 4Read the wheel speed with diagnostic equipment and replace the sensor or wiring as needed
- 5The braking system is safety critical: do not work on the ABS system yourself; leave this to a workshop, and drive carefully until the fault is fixed
Symptoms you may notice5
- ABS does not work or activates suddenly
- Anti-spin function does not work
- Hill descent assist does not work
- Hill start assist does not work
- Front monitoring and active safety do not work
