Go to step 17.
NO -
Replace the original yaw rate-lateral/longitudinal acceleration sensor See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Yaw Rate Sensor/Service and Repair.?
17. Update the VSA modulator-control unit if it does not have the latest software See: Brakes and Traction Control/Antilock Brakes / Traction
Control Systems/Traction Control Module/Testing and Inspection. If the unit already has the latest software, substitute a known-good VSA
modulator-control unit See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Traction Control Module/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 See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Traction Control Module/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 See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Traction Control
Module/Service and Repair. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.?
134
VSA DTC Troubleshooting: 134
DTC 134:
Steering Angle Sensor Malfunction
NOTE: 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 134 at the same time?

Do the DTC 91 troubleshooting See: 91/VSA System.?
NO -
Go to step 3.
3. Put the vehicle on a level surface, and center the steering wheel spokes.
4. Check STEERING ANGLE in the VSA DATA LIST with the HDS.
With the front wheels in the straight ahead position, is STEERING ANGLE 0 掳 卤 5 掳?
YES -
Go to step 5.
NO -
Check the installation of the steering angle sensor See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Steering Angle
Sensor/Service and Repair. If installation is good, do the VSA sensor neutral position memorization See: Brakes and Traction Control/Antilock
Brakes / Traction Control Systems/Testing and Inspection/Programming and Relearning.?
