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 See: Brakes and Traction Control/Antilock Brakes / Traction
Control Systems/Yaw Rate 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 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.?
