DTC 27-26: Steering Angle Sensor DIAG Signal Error (Main.

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 27-11 or 27-26 indicated?

YES - Go to step 5.

NO - Intermittent failure, the system is OK at this time. Check for loose terminals between the steering angle 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 steering angle sensor 5P connector.
7. Disconnect the yaw rate-lateral acceleration sensor 5P connector.
8. Disconnect the VSA modulator-control unit 37P connector.
9. Check for continuity between body ground and steering angle sensor 5P connector terminals No. 3 and No. 5 individually.





Is there continuity?

YES - Repair Short to body ground in the wire between the steering angle sensor and the VSA modulator-control unit.

NO - Go to step 10.

10. Check for continuity between the VSA modulator-control unit 37P connector terminal and the steering angle sensor 5P connector terminal individually.





Is there continuity?

YES - Go to step 11.

NO - Repair open in the wire between the steering angle sensor and the VSA modulator-control unit.

11. Turn the ignition switch ON (II).
12. Measure voltage between steering angle sensor 5P connector terminal No. 3 and body ground.





Is there 0.1 V or more?

YES - Repair Short to power in the wire between the steering angle sensor and the VSA modulator-control unit.

NO - Replace the steering angle sensor.
