DTC 27: Steering Angle Sensor

  1. Check the size, air pressure, and the amount of wear of all four tires, and check the wheel alignment (see FRONT AND REAR SUSPENSION (WHEEL ALIGNMENT) ).

    Is the tire condition and wheel alignment OK? 

    YES  -Go to step 2.

    NO  -Make sure the suspension is not modified, and adjust the wheel alignment correctly, and recheck by test-driving.

  2. Turn the ignition switch to ON (II).
  3. Clear the DTC with the HDS.
  4. Slowly drive the vehicle straight ahead without turning the steering wheel for 10 ft (3 m) or more, then park the vehicle while holding the steering wheel in the straight ahead position.
  5. Check the STEERING ANGLE in the VSA DATA LIST with the HDS.

    Is it 0° ±3 °? 

    YES  -Go to step  7.

    NO  -Go to step 6.

  6. Do the VSA sensor neutral position memorization (see SENSOR CLUSTER REPLACEMENT ).
  7. Test-drive the vehicle around a number of corners.
    NOTE: Drive the vehicle on the road, not on a lift.
  8. Check for DTCs with the HDS.

    Is DTC 27 indicated? 

    YES  -Go to step 9.

    NO  -If DTC 86 is indicated, do the DTC 86 troubleshooting first (see DTC 86: F-CAN COMMUNICATION ). If no DTCs are indicated, the system is OK at this time.

  9. Turn the ignition switch to LOCK (0).
  10. Substitute a known-good steering angle sensor (see STEERING ANGLE SENSOR REPLACEMENT ).
  11. Turn the ignition switch to ON (II).
  12. Clear the DTC with the HDS.
  13. Do the VSA sensor neutral position memorization (see SENSOR CLUSTER REPLACEMENT ).

  15. Check for DTCs with the HDS.

    Is DTC 27 indicated? 

    YES  -Go to step 16.

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

  16. Turn the ignition switch to LOCK (0).
  17. Substitute a known-good sensor cluster (see SENSOR CLUSTER REPLACEMENT ).
  18. Turn the ignition switch to ON (II).
  19. Clear the DTC with the HDS.
  20. Do the VSA sensor neutral position memorization (see SENSOR CLUSTER REPLACEMENT ).
  21. Test-drive the vehicle around a number of corners.
    NOTE: Drive the vehicle on the road, not on a lift.
  22. Check for DTCs with the HDS.

    Is DTC 27 indicated? 

    YES  -Check for loose terminals in the VSA modulator-control unit 47P connector. If necessary, substitute a known-good VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION ), and retest.

    NO  -Replace the original sensor cluster (see SENSOR CLUSTER REPLACEMENT ).
