DTC 27: Steering Angle Sensor

  1. Clear the DTC using the HDS (see HOW TO RETRIEVE DTCS  ).
  2. Disconnect the HDS from the 16P DLC.
  3. Turn the ignition switch OFF, then turn it ON (II) again.
  4. Test-drive the vehicle around a number of corners.
  5. Verify the DTC.

    Is DTC 64 indicated? 

    YES  - Do the appropriate troubleshooting for the DTC.

    NO  - Go to step 6.

  6. Turn the ignition switch OFF.
  7. Disconnect the VSA control unit 47P connector, steering angle sensor 5P connector and yaw rate-lateral acceleration sensor 5P connector.
  8. Turn the ignition switch ON (II).
  9. Measure the voltage between body ground and the VSA control unit 47P connector terminal No. 33, No. 35 individually.

    Is there 1 V or more? 

    YES  - Repair short to power in the wire between the VSA control unit, the steering angle sensor and the yaw rate-lateral acceleration sensor.

    NO  - Go to step 10.

  10. Measure the voltage between body ground and the VSA control unit 47P connector terminal No. 28, No. 29, and No. 43 individually.

    Is there 1 V or more? 

    YES  - Repair short to power in the wire between the VSA control unit, the steering angle sensor and the yaw rate-lateral acceleration sensor.

    NO  - Go to step 11.

  11. Turn the ignition switch OFF.
  12. Check for continuity between body ground and the VSA control unit 47P connector terminal No. 33, No. 35 individually.

    Is there continuity? 

    YES  - Repair short to body ground in the wire between the VSA control unit, the steering angle sensor and the yaw rate-lateral acceleration sensor.

    NO  - Go to step 14.

  14. Check for continuity between the VSA control unit 47P connector terminal No. 33, No. 35 and steering angle sensor 5P connector terminal No. 1, No. 5 individually.

    Is there continuity? 

    YES  - Go to step 16.

    NO  - Repair open in the wire between the VSA control unit and the steering angle sensor.

  16. Substitute a known-good steering angle sensor.
  17. Reconnect all of the disconnected connectors.
  18. Clear the DTC using the HDS (see HOW TO RETRIEVE DTCS  ).
  19. Disconnect the HDS from the 16P DLC.
  20. Turn the ignition switch OFF, then turn it ON (II) again.
  21. Test-drive the vehicle around a number of corners.
  22. Verify the DTC.

    Is DTC 27 indicated? 

    YES  - Check for loose terminals and repair if necessary. Replace the VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION  ).

    NO  - Replace the original steering angle sensor (see STEERING ANGLE SENSOR REPLACEMENT  ).
