DTC Troubleshooting: 11-13, 13-13, 15-13, 17-13

DTC 11-13:  Right-front Wheel Sensor Circuit Malfunction
  
  
DTC 15-13:  Right-rear Wheel Sensor Circuit Malfunction
  
  


1.Turn the ignition switch ON (II).

2.Clear the DTC with the HDS.

3.Check for DTCs with the HDS.

Is DTC 11-13, 13-13, 15-13, and/or 17-13 indicated?


YES - Go to 4.


NO - Intermittent failure, the system is OK at this time. Check for loose terminals between the wheel sensor 2P connector and the ABS modulator-control unit 25P connector. Refer to intermittent failures troubleshooting.n


4.Turn the ignition switch OFF.

5.Disconnect the ABS modulator-control unit 25P connector.

6.Check for continuity between the appropriate ABS modulator-control unit 25P connector wheel sensor +B and GND terminals (see table), then check for continuity between the same terminals and reverse the positive and negative tester probes.

DTC ABS Modulator-control Unit 25P
Connector Terminal No. 
11-13 No. 2 No. 18 
13-13 No. 12 No. 3 
15-13 No. 6 No. 15 
17-13 No. 14 No. 5 

 

Is there continuity in both directions?


YES - Go to 7.


NO - If there is not continuity in both directions, go to 9. If there is continuity in only one direction, go to 11.

7.Disconnect the appropriate wheel sensor 2P connector.

8.Check for continuity between appropriate wheel sensor 2P connector terminals No. 1 and No. 2, then check for continuity between the same terminals and reverse the positive and negative tester probes.

 

Is there continuity in both directions?


YES - Replace the appropriate wheel sensor.n


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

9.Disconnect the appropriate wheel sensor 2P connector.

10.Check for continuity between appropriate wheel sensor 2P connector terminals No. 1 and No. 2, then check for continuity between the same terminals and reverse the positive and negative tester probes.

 

Is there continuity in only one direction?


YES - Repair open in the wire between the appropriate wheel sensor and the ABS modulator-control unit.n


NO - Replace the appropriate wheel sensor.n

11.Check for continuity between body ground and the appropriate ABS modulator-control unit 25P connector terminal (see table).

DTC ABS Modulator-control Unit 25P
Connector Terminal No. 
11-13 No. 2 No. 18 
13-13 No. 12 No. 3 
15-13 No. 6 No. 15 
17-13 No. 14 No. 5 

 

Is there continuity?


YES - Go to 12.


NO - Go to 14.


12.Disconnect the appropriate wheel sensor 2P connector.

13.Check for continuity between body ground and appropriate wheel sensor 2P connector terminal No. 1 and No. 2.

NOTE: Check the wheel sensor with mounted on the vehicle.

 

Is there continuity?


YES - Replace the appropriate wheel sensor.n


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


14.Turn the ignition switch ON (II).

15.Measure voltage between body ground and the appropriate ABS modulator-control unit 25P connector terminal (see table).

DTC ABS Modulator-control Unit 25P
Connector Terminal No. 
11-13 No. 2 No. 18 
13-13 No. 12 No. 3 
15-13 No. 6 No. 15 
17-13 No. 14 No. 5 

 

Is there 0.1 V or more?


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


NO - Check for loose terminals in the ABS modulator-control unit 25P connector. If necessary, substitute a known-good ABS modulator-control unit and retest: Except K20Z2 engine model, K20Z2 engine model.n
