DTC 12-3

DTC 12-1, 12-2, 12-3: Lateral/Longitudinal Acceleration Sensor Malfunction

NOTE: Before you troubleshoot, review the general troubleshooting information.

1. Turn the ignition switch ON (II).
2. Make sure the HDS communicates with the vehicle and the SH-AWD control unit. If it doesn't, troubleshoot the DLC circuit.
3. Check for DTCs in the VSA system with the HDS.

Are any VSA System DTCs indicated?

YES - Go to the indicated DTC's troubleshooting.

NO - Go to step 4.

4. Place the vehicle on a flat surface and compare the lateral G sensor and the lateral G sensor neutral position data in the DATA LIST with the HDS.

Is there difference between those two within 0.2 V?

YES - Replace the yaw rate-lateral/longitudinal acceleration sensor.

NO - Do the yaw rate-lateral/longitudinal acceleration neutral position memorization. Neutral Position Memorization
