Park Brake Force Sensor Circuit Malfunction
The EPB module has detected an electrical fault in the clamp-force sensor circuit. Without this signal, regulated clamping force cannot be ensured and a fallback strategy is used.
Affected components
- Epb force sensor
- Epb module
- Sensor wiring
Common causes
- High likelihood: Clamp-force sensor failed
- Medium likelihood: Wiring or connector fault
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
