- Disconnect the ABS control unit 25P connector.
- Start the engine.
- Measure the voltage between the appropriate wheel sensor (+) circuit terminal and body ground (see table).
DTC Appropriate Terminal 11 (Right-front) No. 18: FRW (+) 13 (Left-front) No. 3: FLW (+) 15 (Right-rear) No. 15: RRW (+) 17 (Left-rear) No. 5: RLW (+)
ABS CONTROL UNIT 25P CONNECTOR
Wire side of female terminals
Is there battery voltage?
YES - Repair short to power in the (+) circuit wire between the ABS control unit and the appropriate wheel sensor. 
NO - Go to step 4.
- Turn the ignition switch OFF.
- Check for continuity between the appropriate wheel sensor (+) circuit terminal and body ground (see table).
| DTC | Appropriate Terminal |
| 11 (Right-front) | No. 18: FRW (+) |
| 13 (Left-front) | No. 3: FLW (+) |
| 15 (Right-rear) | No. 15: RRW (+) |
| 17 (Left-rear) | No. 5: RLW (+) |
ABS CONTROL UNIT 25P CONNECTOR
Wire side of female terminals
Is there continuity?
YES - Go to step 6.
NO - Go to step 7.
- Disconnect the harness 2P connector from the appropriate wheel sensor, then check for continuity between the (+) and ( - ) terminals of the harness and body ground.
Is there continuity?
YES - Repair short to body ground in the (+) or ( - ) circuit wire between the ABS control unit and the wheel sensor.
NO - Replace the wheel sensor.
