Okay, the story continues. The steering angle sensor is changed today (steering column replacement). After ten minutes on the road...you guessed it...the light returns. Ther is one road which almost always sets the warning light so I think I can eliminate the power relay. What I am convinced is that we are dealing witha bad sensor (sideway acceleration. yaw, or brake pressure) that is causing other items in the system to set a code. I am beginning to lose my patience with this truck and dealer. Anyone know what other sensors are in the system and where they are located? Thanks.
