3-7

Active Damper System DTC Troubleshooting: 3-1, 3-3, 3-6, 3-7, 3-9, 3-A

DTC 3-1: Yaw Rate-Lateral/Longitudinal Acceleration Sensor Range/Performance Problem (Yaw Rate Signal-Lateral Acceleration Signal Incorrect Correlation)

DTC 3-3: Yaw Rate-Lateral/Longitudinal Acceleration Sensor Malfunction (Lateral Acceleration Sensor)

DTC 3-6: Yaw Rate-Lateral/Longitudinal Acceleration Sensor Malfunction (Yaw Rate Sensor)

DTC 3-7: Yaw Rate-Lateral/Longitudinal Acceleration Sensor Range/Performance Problem (Wheel Speed Signal-Longitudinal Acceleration Signal Incorrect Correlation)

DTC 3-9: Yaw Rate-Lateral/Longitudinal Acceleration Sensor Malfunction (Longitudinal Acceleration Sensor)

DTC 3-A: Yaw Rate-Lateral/Longitudinal Acceleration Sensor Malfunction

NOTE: If DTC 8-6 is stored at the same time as DTC 3-1, DTC 3-3, DTC 3-6, DTC 3-7, DTC 3-9, or DTC 3-A, troubleshoot DTC 8-6 first, then recheck for DTC 3-1, DTC 3-3, DTC 3-6, DTC 3-7, DTC 3-9, or DTC 3-A.

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

2. Clear the DTC with the HDS.

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

4. Test-drive the vehicle around a corner for 2 seconds or more.

5. Check for DTCs with the HDS.

Is DTC 3-1, 3-3, 3-6, 3-7, 3-9, or 3-A indicated?
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. Initial Inspection and Diagnostic Overview

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. 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.

13. Check for DTCs with the HDS.

Is DTC 3-1, 3-3, 3-6, 3-7, 3-9, or 3-A indicated?
YES - Replace the active damper control unit. Service and Repair

NO - Replace the original yaw rate-lateral/longitudinal acceleration sensor. Service and Repair
