I have a 2006 GMC Envoy! The Code C0455 appears, I replaced the Steering Angle Sensor, the steering wheel was not locked when it was replaced and the battery was not disconnected and reconnected after the install. The Service Stabilitrak light shows on the dash with skidmark in the triangle indicator showing as well! I'm outta what to do's on this. No other codes.

Has the TSB #07-05-25-001 been performed? Involves a reflash for this specific code.

If not done see your local friendly authorized GMC dealer.
