## 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
