DTC 11, 13, 15, 17: Wheel Sensor (Open/Short to Body Ground/Short to Power)

1. Disconnect the ABS control unit 31P connector.
2. Start the engine.
3. Measure the voltage between the appropriate wheel sensor (+) circuit terminal of the ABS control unit 31P connector and body ground (see table).

   DTC | Appropriate Terminal
   11 (Right-front) | No. 5: FRS (+)
   13 (Left-front) | No. 7: FLS (+)
   15 (Right-rear) | No. 2: RRS (+)
   17 (Left-rear) | No. 9: RLS (+)

ABS CONTROL UNIT 31P CONNECTOR

Wire side of female terminals

Is there battery voltage?

YES - Repair short to power in the (+) circuit wire between the ABS modulator-control unit and the appropriate wheel sensor.

NO - Go to step 4.

4. Turn the ignition switch OFF.

5. Check for continuity between the appropriate wheel sensor (+) circuit terminal and body ground (see table).

DTC | Appropriate Terminal
11 (Right-front) | No. 5: FRS (+)
13 (Left-front) | No. 7: FLS (+)
15 (Right-rear) | No. 2: RRS (+)
17 (Left-rear) | No. 9: RLS (+)

ABS CONTROL UNIT 31P CONNECTOR

Wire side of female terminals

Is there continuity?

YES - Go to step 6.

NO - Go to step 7.

6. 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 modulator-control unit and the wheel sensor.

NO - Replace the wheel sensor.
