The diagnostic trouble code (DTC) shows that the steering wheel angle sensor may be incorrectly installed. It is extremely important that the contact reel/steering wheel angle sensor is installed correctly. If the unit is installed with the turning central section one turn out of place, full steering lock can break internal components. If this has occurred, replace the contact reel.

• Ignition off.
• Align the wheels in the straight ahead position.
• Remove the steering wheel.

Check that the white markings are visible in the contact reel window when the wheels are in the straight ahead position. If the steering wheel angle is incorrect the contact roller shall be adjusted so that the white marking is visible in the contact roller's window when the contact roller's lock screw is located in the correct position.

Remedy as necessary.
