DTC 15-1

DTC 15-1: Longitudinal Acceleration Sensor Malfunction

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

1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. 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 4.

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

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

Is there 0.1 G or less?

YES - Go to step 6.

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

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