Wheel Speed Sensor Short Circuited Coil Detection (IA right)
- Check wiring and the relating electric connectors of the relevant wheel speed sensor (shorted sensor wires IG/IGM?) - Check wheel speed sensor (internal shorted coil?) - Replace the ABS-ECU, if the wiring and the wheel speed sensor are 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 only deactivated, if the intermediate axle
Diagnostic depth
A short circuited coil of the right wheel speed sensor at the intermediate-axle is detected, if the resistance is too low.
- wiring or electric connectors of the relevant wheel speed sensor are shorted - wheel speed sensor has internal shorted coil - ABS-ECU defective
