YES -
Go to step 6.
NO -
Intermittent failure, the system is OK at this time. Check for poor or loose connections between the yaw rate-lateral/longitudinal acceleration sensor
and the active damper control unit.?
6. Check for VSA system DTCs with the HDS See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and
Inspection/Reading and Clearing Diagnostic Trouble Codes.
Is any DTC indicated?
YES -
Go to the indicated VSA system DTC's troubleshooting.?
NO -
Go to step 7.
7. Turn the ignition switch to LOCK (0).
8. 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.
9. Turn the ignition switch to ON (II).
10. Clear the DTC with the HDS.
11. Turn the ignition switch to LOCK (0).
12. Test-drive the vehicle around a corner for 2 seconds or more.
