- Check the wheel alignment (see WHEEL ALIGNMENT ).
- Check for installation of the steering angle sensor.
- Turn the ignition switch to ON (II).
- Make sure the HDS communicates with vehicle and the SH-AWD control unit. If it doesn't, troubleshoot the DLC circuit (see DLC CIRCUIT TROUBLESHOOTING ).
- Check for DTCs in the VSA system with the HDS.
Are any steering angle sensor DTCs indicated?
YES -Go to the indicated DTCs troubleshooting.

- Check the STEERING ANGLE SENSOR in the DATA LIST with the HDS.
When the steering wheels is turned slowly, does the value change?

NO -Update the SH-AWD control unit if it does not have the latest software (see UPDATING THE SH-AWD CONTROL UNIT ), or substitute a known-good SH-AWD control unit (see SH-AWD Control Unit Replacement ) and recheck. If the symptom/indication goes away with the updated SH-AWD control unit, troubleshooting is complete. If the symptom/indication goes away with a known-good SH-AWD control unit, replace the original SH-AWD control unit (see SH-AWD Control Unit Replacement ).
