DTC 15-1: Longitudinal Acceleration Sensor Malfunction

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

1. Turn the ignition switch to ON (II).
2. Make sure the HDS communicates with vehicle and the SHAWD control unit. If it doesn't, troubleshoot the DLC circuit.
3. Clear the DTC with the HDS.
4. Test-drive the vehicle with an assistant. When accelerating, check the LONGITUDINAL ACCELERATION SENSOR in the DATA LIST with the HDS.

Does the sensor value change when acceleration?

YES - Go to step 5.

NO - Replace the yaw rate-lateral/longitudinal acceleration sensor.

5. Park the vehicle on a level surface.
6. Check the LONGITUDINAL ACCELERATION SENSOR in the DATA LIST with the HDS.

Is there 0.1 G or less?

YES - Go to step 7.

NO - Do the yaw rate-lateral/longitudinal acceleration neutral position memorization. Programming and Relearning If the DTC: returns, replace the SH-AWD control unit.

7. Test-drive the vehicle for 2 minutes in a vehicle speed is kept constant at 19 mph (30 km/h).
8. Check for DTCs with the HDS.

Is DTC 15-1 indicated?

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

NO - Intermittent failure, the system is OK at this time. If the DTC returns, replace the SH-AWD control unit.
