Lining Wear Sensor Wheel 5 : too high difference between the two signals on this and on the other side of the axle
Measure actual wear values externally. Compare them with the wear values measured by the EBS system (read out via diagnostics). If they match, check brake calipers, disc and pads. calculate wear values, Check lining wear sensor Otherwise check connection resistance between lining wear sensor and EPM, including increased resistance of connectors due to e.g. corrosion.
What you'll see
No driver-visible symptom recorded.
System reaction
No user function restricted. Lining Wear Warning Lamp.
Diagnostic depth
The error is set if the difference between left and right pads of an axle exceeds the configured limit. (Default value is 20%)
