| DTC 27: | Steering Angle Sensor |
| 1. | Turn the ignition switch OFF. |
| 2. | Disconnect the VSA control unit 46P connector and steering angle sensor 5P connector. |
| 3. | Check for continuity between the VSA control unit 46P connector terminal No. 33, No. 35 and steering angle sensor 5P connector terminal No. 5, No. 1 individually.
Is there continuity? YES - Go to 4. NO - Repair open in the wire between the VSA modulator-control unit and steering angle sensor.n |
| 4. | Turn the ignition switch ON (II). |
| 5. | Measure the voltage between body ground and the VSA control unit 46P connector terminal No. 33, No. 35 individually.
Is there 1 V or more? YES - Repair short to power in the wire between the VSA modulator-control unit and steering angle sensor.n NO - Go to 6. |
| 6. | Check for continuity between the VSA control unit 46P connector terminal No. 2, No. 25, No. 26 and steering angle sensor 5P connector terminal No. 2, No. 4, No. 3 individually.
Is there continuity? YES - Repair open in the wire between the VSA modulator-control unit and steering angle sensor.n NO - Go to 7. |
| 7. | Measure the voltage between body ground and the VSA control unit 46P connector terminal No. 2, No. 25 and No. 26 individually.
Is there 1 V or more? YES - Repair short to power in the wire between the VSA modulator-control unit and steering angle sensor.n NO - Go to 8. |
| 8. | Turn the ignition switch OFF. |
| 9. | Check for continuity between body ground and the VSA control unit 46P connector terminals No. 2, No. 25, No. 26, No. 33, and No. 35 individually.
Is there continuity? YES - Repair short to the body ground in the wire between the VSA modulator-control unit and steering angle sensor.n NO - Go to 10. |
| 10. | Substitute a known-good steering angle sensor. |
| 11. | Reconnect all of disconnected connectors. |
| 12. | Clear the DTCs using the HDS. |
| 13. | Turn the ignition switch OFF, then turn it ON (II). |
| 14. | Test-drive the vehicle around a number of corners. |
| 15. | Verify the DTC. Is DTC 27 indicated? YES - Check for loose connector terminals and repair if necessary. Replace the VSA modulator-control unit.n NO - Replace the original steering angle sensor.n |
