DTC 27-11, 27-26: Steering Angle Sensor DIAG Signal Error (Initial); Steering Angle Sensor DIAG Signal Error (Main)
- Turn the ignition switch to ON (II).
- Clear the DTC with the HDS.
- Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
- 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. Refer to intermittent failures troubleshooting (see Intermittent Failures ).
- Turn the ignition switch to LOCK (0).
- Disconnect the steering angle sensor 5P connector (see STEERING ANGLE SENSOR REPLACEMENT ).
- Disconnect the VSA modulator-control unit 36P connector (see step 3 ).
- Check for continuity between body ground and steering angle sensor 5P connector terminals No. 2, No. 3, No. 4, 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 9.
- Check for continuity between the VSA modulator-control unit 36P connector terminal and the steering angle sensor 5P connector terminal individually.CONNECTOR TERMINAL REFERENCE TABLE

Is there continuity?
YES - Go to step 10.
NO - Repair open in the wire between the steering angle sensor and the VSA modulator-control unit.
- Substitute a known-good steering angle sensor (see STEERING ANGLE SENSOR REPLACEMENT ).
- Reconnect all connectors.
- Turn the ignition switch to ON (II).
- Clear the DTC with the HDS.
- Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
- Check for DTCs with the HDS.
Is DTC 27-11 or 27-26 indicated?
YES - Go to step 16.
NO - Replace the original steering angle sensor (see STEERING ANGLE SENSOR REPLACEMENT ).
- Update the VSA modulator-control unit if it does not have the latest software (see VSA MODULATOR-CONTROL UNIT UPDATE ).
- Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
- Check for DTCs with the HDS.
Is DTC 27-11 or 27-26 indicated?
YES - Check for loose terminals in the VSA modulator-control unit 36P connector. If the symptom/indication is still present. Replace the VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION ).
NO - If the VSA modulator-control unit was updated, troubleshooting is complete. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.
