Wheel Speed Sensor Short Circuit to UB Detection (RA left)
â–¶ How to fix
- Check wiring and the relating electric connectors of the relevant wheel speed sensor (short circuit to UB?) - Replace the ABS-ECU, if the wiring of the wheel speed sensor is faultless
What you'll see
No driver-visible symptom recorded.
System reaction
ABS function at relevant wheel is switched off ABS function at other wheels is still available ATC engine and brake control is switched off HSA is deactivated EBL is not deactivated Drag Torque Control is deactivated
Diagnostic depth
Detection
A short circuit to UB of the left rear wheel speed sensor is detected. The measured analogous voltage is outside a certain range.
Possible cause
- wiring or relating electric connectors of the relevant wheel speed sensor is shorted to UB - ABS-ECU defetctive
