- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between the DSC HU/CM connector terminals (vehicle harness-side) and the following vehicle harness-side connector terminals of the ABS wheel-speed sensors:
- RF ABS wheel-speed sensor (+): R-B
- RF ABS wheel-speed sensor(-): O-A
- LF ABS wheel-speed sensor (+): S-B
- LF ABS wheel-speed sensor(-): P-A
- RR ABS wheel-speed sensor (+): M-B
- RR ABS wheel-speed sensor (-): J-A
- LR ABS wheel-speed sensor (+): L-B
- LR ABS wheel-speed sensor(-): I-A
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to ground.
