DTC 19-2

DTC 19-2: Steering Angle Sensor (Short)

NOTE: Before you troubleshoot, review the general troubleshooting information.

1. Turn the ignition switch ON (II).
2. Make sure the HDS communicates with the vehicle and the SH-AWD control unit. If it doesn't, troubleshoot the DLC circuit.
3. Clear the DTC with the HDS.
4. Start the engine.
5. Check for DTCs with the HDS.

Is DTC 19-2 indicated?

YES - Go to step 6.

NO - Intermittent failure, the system is OK at this time.

6. Check the counter value of the steering angle sensor with the HDS.

Does the counter value change according to the steering wheel angle?

YES - Go to step 7.

NO - Go to step 16.

7. Turn the ignition switch OFF.
8. Disconnect SH-AWD control unit connector A (26P).
9. Turn the ignition switch ON (II).
10. Measure the voltage between SH-AWD control unit connector terminals A8 and Al2.





Is there 0.3 V or more when the steering wheel is in the neutral position (straight ahead)?

YES - Go to step 11.

NO - Replace the SH-AWD control unit.

11. Turn the ignition switch ON (II).
12. Disconnect the steering sensor 5P connector.
13. Check for continuity between SH-AWD control unit connector terminal A8 and body ground.





Is there continuity?

YES - Go to step 14.

NO - Check for DTCs in the VSA system. If there are VSA system DTCs, go to the indicated DTC's troubleshooting. If no DTCs are indicated, intermittent failure, the system is OK at this time. Check for loose connector terminals at the SH-AWD control unit, and repair if necessary.

14. Disconnect the AFS control unit 40P connector.
15. Check for continuity between SH-AWD control unit connector terminal A8 and body ground.





Is there continuity?

YES-Repair short in the wire between SH-AWD control unit connector A and the AFS control unit 40P connector.

NO-Check for DTCs in the VSA system. If there are VSA system DTCs, go to the indicated DTC's troubleshooting. If no DTCs are indicated, intermittent failure, the system is OK at this time. Check for loose connector terminals at the SH-AWD control unit, and repair if necessary.

16. Turn the ignition switch OFF.
17. Disconnect SH-AWD control unit connector A (26P).
18. Turn the ignition switch ON (II).
19. Measure the voltage between SH-AWD control unit connector terminals A12 and A22.





Does the output voltage change from 1.5 - 4 V according to the steering wheel angle?

YES - Go to step 26.

NO - Go to step 20.

20. Turn the ignition switch OFF.
21. Disconnect the steering sensor 5P connector.
22. Check for continuity between SH-AWD control unit connector terminal A22 and steering angle sensor 5P connector terminal No. 2.





Is there continuity?

YES - Go to step 23.

NO - Repair open in the wire between SH-AWD control unit connector A and the steering angle sensor connector.

23. Check for continuity between SH-AWD control unit connector terminal A22 and body ground.





Is there continuity?

YES - Go to step 24.

NO - Check for DTCs in the VSA system. If there are VSA system DTCs, go to the indicated DTC's troubleshooting. If no DTCs are indicated, intermittent failure, the system is OK at this time. Check for loose connector terminals at the SH-AWD control unit, and repair if necessary.

24. Disconnect the AFS control unit 40P connector.
25. Check for continuity between SH-AWD control unit connector terminal A22 and body ground.





Is there continuity?

YES - Repair short in the wire between SH-AWD control unit connector A and the AFS control unit 40P connector.

NO - Check for DTCs in the VSA system. If there are VSA system DTCs, go to the indicated DTC's troubleshooting. If no DTCs are indicated, intermittent failure, the system is OK at this time. Check for loose connector terminals at the SH-AWD control unit, and repair if necessary.

26. Measure the voltage between SH-AWD control unit connector terminal A12 and A21.





Does the output voltage change from 0 - 5 V according to the steering wheel angle?

YES - Go to step 33.

NO - Go to step 27.

27. Turn the ignition switch OFF.
28. Disconnect the steering angle sensor 5P connector.
29. Check for continuity between SH-AWD control unit connector terminal A21 and steering angle sensor 5P connector terminal No. 4.





Is there continuity?

YES - Go to step 30.

NO - Repair open in the wire between SH-AWD control unit connector A and the steering angle sensor.

30. Check for continuity between SH-AWD control unit connector terminal A21 and body ground.





Is there continuity?

YES - Go to step 31.

NO - Check for DTCs in the VSA system. If there are VSA system DTCs, go to the indicated DTC's troubleshooting. If no DTCs are indicated, intermittent failure, the system is OK at this time. Check for loose connector terminals at the SH-AWD control unit, and repair if necessary.

31. Disconnect the AFS control unit 40P connector.
32. Check for continuity between SH-AWD control unit connector terminal A21 and body ground.





Is there continuity?

YES - Repair short in the wire between SH-AWD control unit connector A and the AFS control unit 40P connector.

NO - Check for DTCs in the VSA system. If there are VSA system DTCs, go to the indicated DTC's troubleshooting. If no DTCs are indicated, intermittent failure, the system is OK at this time. Check for loose connector terminals at the SH-AWD control unit, and repair if necessary.
