NOTE:

- Driving on an extremely angled road can cause this DTC.
- Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.

1. Turn the ignition switch to ON (II).

2. Check for DTCs with the HDS.

Is DTC 91 indicated with DTC 132, 133, 135, or 136 at the same time?

YES -

Do the DTC 91 troubleshooting VSA System.�

NO -

Go to step 3.

3. Turn the ignition switch to LOCK (0).

4. Check that the yaw rate-lateral/longitudinal acceleration sensor is properly mounted Service and Repair.

Is the yaw rate-lateral/longitudinal acceleration sensor installation OK?

YES -

Go to step 5.

NO -

Reinstall the yaw rate-lateral/longitudinal acceleration sensor Service and Repair, and retest by test-driving.�

5. Put the vehicle on a level surface.

6. Turn the ignition switch to ON (II).

7. Check the LATERAL ACCELERATION SENSOR and LONGITUDINAL ACCELERATION SENSOR in the VSA DATA LIST with the HDS.

Is 0 ± 1 m/s indicated ?

YES -

Go to step 8.

NO -

Replace the yaw rate-lateral/longitudinal acceleration sensor Service and Repair.�

8. Clear the DTC with the HDS.

9. Test-drive the vehicle around a number of corners.

10. Check for DTCs with the HDS.

Is DTC 132, 133, 135, or 136 indicated?

YES -

Go to step 11.

NO -

Intermittent failure, the system is OK at this time. Check for loose terminals between the yaw rate-lateral/longitudinal acceleration sensor 4P connector, and the VSA modulator-control unit 47P connector. Refer to intermittent failures troubleshooting.�

11. Turn the ignition switch to LOCK (0).

12. Substitute a known-good yaw rate-lateral/longitudinal acceleration sensor Service and Repair.

13. Turn the ignition switch to ON (II).

14. Clear the DTC with the HDS.

15. Test-drive the vehicle around a number of corners.

NOTE: Drive the vehicle on the road, not on a lift.

16. Check for DTCs with the HDS.

Is DTC 132, 133, 135, or 136 indicated?

YES -

Go to step 17.

NO -

Replace the original yaw rate-lateral/longitudinal acceleration sensor Service and Repair.�

17. Update the VSA modulator-control unit if it does not have the latest software Testing and Inspection. If the unit already has the latest software, substitute a known-good VSA modulator-control unit Service and Repair.

18. Test-drive the vehicle around a number of corners.

NOTE: Drive the vehicle on the road, not on a lift.

19. Check for DTCs with the HDS.

Is DTC 132, 133, 135, or 136 indicated?

YES -

Check for loose terminals in the VSA modulator-control unit 46P connector. Check for a loose connection at G303. If the VSA modulator-control unit was updated, substitute a known-good VSA modulator-control unit Service and Repair, then retest. If the VSA modulator-control unit was substituted, go to step 1.

NO -

If the VSA modulator-control unit was updated, troubleshooting is complete. If the VSA modulator-control unit was substituted, replace the original VSA modulator-control unit Service and Repair. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.�
