21. Check for continuity between SH-AWD control unit connector terminal A8 and body ground.
Is there continuity?
YES - Go to step 22.
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.
22. Disconnect the AFS control unit 40P connector.
23. 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.
24. Measure 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 31.
NO - Go to step 25.
25. Turn the ignition switch OFF.
26. Disconnect the steering sensor 5P connector.
27. Check for continuity between SH-AWD control unit connector terminal A21 and steering sensor 5P connector terminal No. 4.
Is there continuity?
YES - Go to step 28.
NO - Repair open in the wire between SH-AWD control unit connector A and the steering angle sensor.
28. Check for continuity between SH-AWD control unit connector terminal A21 and body ground.
Is there continuity?
YES - Go to step 29.
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.
29. Disconnect the AFS control unit 40P connector.
30. 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.
