BCM-C100A62 - Brake Pedal Angle Sensor. Algorithm Based Failures. Signal compare 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 compared the signals from the brake pedal angle sensor and found that they do not agree. The sensor consists of two sensors, and the fault most often lies in the sensor or in its wiring.
Possible causes
- Damaged wiring to the brake pedal angle sensor
- Damaged brake pedal angle 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 brake pedal angle sensor and in the sensor itself
- 3Check the angle sensor with diagnostic equipment and replace it if damaged
- 4The braking system is safety critical: do not work on the brake pedal sensor yourself; leave this to a workshop, and drive carefully until the fault is fixed
Symptoms you may notice4
- Anti-spin function does not work
- Hill descent assist does not work
- Hill start assist does not work
- Front monitoring and adaptive cruise control do not work
