DTC 16-1

DTC 16-1: Steering Angle Sensor Signal

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. Check the steering angle sensor in the DATA LIST with the HDS.

When the steering wheel is turned slowly, does the value change?

YES - Intermittent failure, the system is OK at this time.

NO - Go to step 4.

4. Turn the ignition switch OFF.
5. Disconnect SH-AWD control unit connector A (26P).
6. Turn the ignition switch ON (II). Measure the voltage between SH-AWD control unit connector terminals Al2 and A22.

Does the voltage change from about 1.5 V to 4.0 V when the steering wheel is turned slowly?

YES - Go to step 7.

NO - Go to step 8.

7. Measure the voltage between SH-AWD control unit connector terminals A12 and A21.

Does the voltage change from about 1.5 V to 4.0 V when the steering wheel is turned slowly?

YES - Replace the SH-AWD control unit.

NO - Go to step 11.

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

Is there continuity?

YES - 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.

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

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