Wheel Speed Sensor Short Circuit to GND Detection (IA left)
- Check wiring and the relating electric connectors of the relevant wheel speed sensor (short circuit to GND?) - Check relevant wheel speed sensor (internal short circuit to GND?) - 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 circuit to GND of the left wheel speed sensor at the intermediate-axle is detected, if the measured analogous voltage is within a certain range. Remark: A wiring-mixture of wheelspeed sensor lines left/right could also lead to failure detections "interruption" or "shorted to GND" on both sides.
- wiring and relating electric connectors of the relevant wheel speed sensor have short circuit to GND - relevant wheel speed sensor has internal short circuit to GND - ABS-ECU defect
