3	INSPECT FOR IMPROPER INSTALLATION OF STEERING ANGLE SENSOR • Inspect the installation of steering angle sensor. • Is there any malfunction?	Yes	Repair installation or replace the steering angle sensor, then go to Step 5. (See STEERING ANGLE SENSOR REMOVAL/INSTALLATION.)
3		No	Go to the next step.
4	INSPECT STEERING ANGLE SENSOR • Inspect the steering angle sensor. (See STEERING ANGLE SENSOR INSPECTION.) • Is there any malfunction?	Yes	Replace the steering angle sensor, then go to the next step. (See STEERING ANGLE SENSOR REMOVAL/INSTALLATION.)
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC using the M-MDS. (See CLEARING DTC [BCM].) • Start the engine and drive the vehicle at 10 km/h {6.2 mph} or more. • Perform the BCM DTC inspection using the M-MDS. (See DTC INSPECTION [BCM].) • Is the same DTC present?	Yes	Replace the BCM, then go to the next step. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [L.H.D.].) (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [R.H.D.].)
5		No	Go to the next step.
6	VERIFY THAT NO OTHER DTCs ARE PRESENT • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [BCM].)
