Common causes
- High likelihood: Valve relay failed
- Medium likelihood: Internal ABS module fault (relay integrated)
- Low likelihood: Power supply wiring or fuse fault
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
