DTC Troubleshooting: 11, 13, 15, 17

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

1.Disconnect the ABS control unit 26P connector.

2.Start the engine.

3.Measure the voltage between body ground and the appropriate wheel sensor +B and GND terminals of the ABS control unit 26P connector individually (see table).

DTC Appropriate Terminal 
+B GND 
11 (Right-front) FR +B:
No. 5 
FR-GND:
No. 6 
13 (Left-front) FL +B:
No. 9 
FL-GND:
No. 8 
15 (Right-rear) RR +B:
No. 11 
RR-GND:
No. 12 
17 (Left-rear) RL +B:

RL-GND:
No. 2 

 

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 4.


4.Turn the ignition switch OFF.

5.Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the ABS control unit 26P connector individually (see table).

Is there continuity?


YES - Go to 6.


NO - Go to 8.

6.Disconnect the appropriate wheel sensor 2P connector.

7.Check for continuity between body ground and the appropriate wheel sensor +B and GND terminals of the ABS control unit 26P connector individually (see table).

RL-GND:
No. 2 

 

Is there continuity?


YES - Repair short to body ground in the wire between the ABS modulator-control unit and the wheel sensor.n


NO - Replace the  wheel sensor.n

8.Measure the resistance between the appropriate wheel sensor +B and GND terminals of the ABS control unit 26P connector (see table), then measure the resistance between the same terminals and reverse the positive and negative tester probes.

+B GND 
11 (Right-front) FR +B:
No. 5 
FR-GND:
No. 6 
13 (Left-front) FL +B:
No. 9 
FL-GND:
No. 8 
15 (Right-rear) RR +B:
No. 11 
RR-GND:
No. 12 
17 (Left-rear) RL +B:
No. 3 
RL-GND:
No. 2 

 

Is the resistance infinity (open circuit) in both directions?


YES - Go to 9.


NO - Go to 11.

9.Disconnect the appropriate wheel sensor 2P connector.

10.Measure the resistance between the appropriate wheel sensor 2P connector terminals, then measure the resistance between the same terminals and reverse the positive and negative tester probes.

 

Is the resistance infinity (open circuit) in both directions?


YES - Replace the  wheel sensor.n


NO - Repair open in the wire between the ABS modulator-control unit and the wheel sensor.n


11.Disconnect the appropriate wheel sensor 2P connector.

12.Check for continuity between the appropriate wheel sensor +B and GND terminals of the ABS control unit 26P connector (see table), then check for continuity between the same terminals and reverse the positive and negative tester probes.

+B GND 
11 (Right-front) FR +B:
No. 5 
FR-GND:
No. 6 
13 (Left-front) FL +B:
No. 9 
FL-GND:

No. 11 
RR-GND:
No. 12 
17 (Left-rear) RL +B:
No. 3 
RL-GND:
No. 2 

 

Is there continuity in both directions?


YES - Repair the wires between the ABS modulator-control unit and the wheel sensor that are shorted to each other.n


NO - Check for loose or poor connections at the ABS control unit 26P connector and the appropriate wheel sensor 2P connector. If the connections are good, replace the appropriate wheel sensor and recheck for DTCs. If the DTC returns, replace the ABS modular-control unit.n
