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
