DTC Troubleshooting: 11, 13, 15, 17

DTC 11, 13, 15, 17:

Wheel Sensor ( Open/Short to Body Ground/Short to Power)

1.	Disconnect the negative cable from the battery.

2.	Disconnect the ABS control unit 25P connector.

3.	Reconnect the battery cable.

4.	Start the engine.

5.

Measure the voltage between body ground and the appropriate wheel sensor + B and GND terminals of the ABS control unit 25P connector individually (see table). DTC  Appropriate Terminal  + B  GND  11 (Right-front)  FR + B: No. 20  FR - GND: No. 19  13 (Left-front)  FR + B: No. 2  FR - GND: No. 1  15 (Right-rear)  RR + B: No. 22  RR - GND: No. 23  17 (Left-rear)  RL + B: No. 6  RL - GND: No. 5    Is there battery voltage? YES - Repair short to power in the wire between the  ABS modulator-control unit and the appropriate  wheel sensor.n NO - Go to 6.

6.	Turn the ignition switch OFF.

7.

Check for continuity between body ground and the appropriate wheel sensor + B and GND terminals of the ABS control unit 25P connector individually (see table). DTC  Appropriate Terminal  + B  GND  11 (Right-front)  FR + B: No. 20  FR - GND: No. 19  13 (Left-front)  FR + B: No. 2  FR - GND: No. 1  15 (Right-rear)  RR + B: No. 22  RR - GND: No. 23  17 (Left-rear)  RL + B: No. 6  RL - GND: No. 5    Is there continuity? YES - Go to 8. NO - Go to 10.

8.	Disconnect the wire harness 2P connector from the appropriate wheel sensor.

9.

Check for continuity between body ground and the appropriate wheel sensor + B and GND terminals of the ABS control unit 25P connector individually (see table). DTC  Appropriate Terminal  + B  GND  11 (Right-front)  FR + B: No. 20  FR - GND: No. 19  13 (Left-front)  FR + B: No. 2  FR - GND: No. 1  15 (Right-rear)  RR + B: No. 22  RR - GND: No. 23  17 (Left-rear)  RL + B: No. 6  RL - GND: No. 5    Is there continuity? YES - Repair short to body ground in the wire between the  ABS modulator-control unit and the  wheel sensor. NO - Replace the wheel sensor.n

10.

Measure the resistance between the appropriate wheel sensor + B and GND terminals of the ABS control unit 25P connector individually (see table), then measure the resistance between same terminals after changing positive tester probe and negative tester probe. DTC  Appropriate Terminal  + B  GND  11 (Right-front)  FR + B: No. 20  FR - GND: No. 19  13 (Left-front)  FR + B: No. 2  FR - GND: No. 1  15 (Right-rear)  RR + B: No. 22  RR - GND: No. 23  17 (Left-rear)  RL + B: No. 6  RL - GND: No. 5    Is the resistance infinity at both sides? YES - Go to 11. NO - Go to 13.

11.	Disconnect the wire harness 2P connector from the appropriate wheel sensor.

12.

Measure the resistance between the appropriate wheel sensor + B and GND terminals of the ABS control unit 25P connector (see table), then measure the resistance between same terminals after changing positive tester probe and negative tester probe. DTC  Appropriate Terminal  + B  GND  11 (Right-front)  FR + B: No. 20  FR - GND: No. 19  13 (Left-front)  FR + B: No. 2  FR - GND: No. 1  15 (Right-rear)  RR + B: No. 22  RR - GND: No. 23  17 (Left-rear)  RL + B: No. 6  RL - GND: No. 5    Is the resistance infinity at both sides? YES - Repair open in the wire between the  ABS modulator-control unit and the  wheel sensor.n NO - Replace the  wheel sensor.n

13.

Check for continuity between the appropriate wheel sensor + B and GND terminals of the ABS control unit 25P connector (see table), then check for continuity between same terminals after changing positive tester probe and negative tester probe. DTC  Appropriate Terminal  + B  GND  11 (Right-front)  FR + B: No. 20  FR - GND: No. 19  13 (Left-front)  FR + B: No. 2  FR - GND: No. 1  15 (Right-rear)  RR + B: No. 22  RR - GND: No. 23  17 (Left-rear)  RL + B: No. 6  RL - GND: No. 5    Is there continuity at both sides? YES - Repair short in the wire between the  ABS modulator-control unit and the  wheel sensor.n NO - Check for a loose ABS control unit 25P connector. If necessary, substitute a known-good  ABS modulator-control unit, and recheck.n
