DTC 26-12

DTC 26-11: Lateral Acceleration Sensor Internal Circuit Malfunction (Initial)

DTC 26-12: Lateral Acceleration Sensor Internal Circuit Malfunction (Open, Short.

1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch OFF, then turn it ON (II) again.
4. Check for DTCs with the HDS.

Is DTC 26-11 or 26-12 indicated?

YES - Go to step 5.

NO - Intermittent failure, the system is OK at this time. Check for loose terminals between the yaw rate-lateral acceleration sensor 5P connector and the VSA modulator-control unit 37P connector. Refer to intermittent failures troubleshooting.

5. Turn the ignition switch OFF.
6. Disconnect the yaw rate-lateral acceleration sensor 5P connector.
7. Disconnect the VSA modulator-control unit 37P connector.
8. Check for continuity between body ground and yaw rate-lateral acceleration sensor 5P connector terminal No. 5.





Is there continuity?

YES - Repair Short to body ground in the wire between the yaw rate-lateral acceleration sensor and the VSA modulator-control unit.

NO - Go to step 9.

9. Check for continuity between the VSA modulator-control unit 37P connector terminal and the yaw rate-lateral acceleration sensor 5P connector terminal individually.





Is there continuity?

YES - Go to step 10.

NO - Repair open in the wire between the yaw rate-lateral acceleration sensor and the VSA modulator-control unit.

10. Turn the ignition switch ON (II).
11. Measure voltage between yaw rate-lateral acceleration sensor 5P connector terminal No. 5 and body ground.





Is there 0.1 V or more?

YES - Repair Short to power in the wire between the yaw rate-lateral acceleration sensor and the VSA modulator-control unit.

NO - Replace the yaw rate-lateral acceleration sensor.
