Speed Wheel-to-Wheel Mismatch
The ABS control module has detected an implausible speed difference between wheels that cannot be explained by cornering. This typically points to one suspect sensor, mismatched tyre sizes or a damaged tone ring.
Affected components
- Wheel speed sensor
- Tone ring
- Tires
- Abs control module
Common causes
- High likelihood: Tyre sizes or wear levels do not match across axles
- Medium likelihood: Tone ring missing teeth on one wheel
- Low likelihood: Wheel speed sensor degraded
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
