  1. Turn ignition switch to OFF position.
  2. Disconnect steering angle sensor connector.
  3. Check for proper connection to steering angle sensor connector terminals at "G33-2" and "G33-3".
  4. If OK, then measure voltage between connector terminal "G33-3" and vehicle body ground.

Is it 10 - 14 V? 		 Go to Step 4. "WHT/RED" wire circuit open.
5  Check steering angle sensor ground circuit 
  1. Turn ignition switch to OFF position.
  2. Measure resistance between connector terminal "G33-2" and vehicle body ground.
