2003 Silverado Quadrasteer troubles

[forest7073]

Hello, looking for help with a Quadrasteer issue... All 3 lights are on by the button.. 2wheel, 4wheel, tow/haul.... I did have the truck in about a month ago for a throttle position sensor issue.. Shortly after I got a service 4 wheel steer indication... The rear tires are turned about 5% + or-...... Have had this to the dealership. At about $200 and know less than when I pulled in... Anyone have any idea what may be the issue with this Quadrasteer. Really sucks going down the road looking out the drivers window... I did find a service bulliten dated back December 2003... Possable programing issue??? Any help would be greatly appreciated...

Ok as I stated I had this at a deaership for the tune of $200... No codes that they were aware of... They actually never had seen a quadrasteer....

then they are dumb as &^%

 

cuz that message means there is a DTC

 

ask first if any techs have had the course or know what a scanner is ,,omg

Yes sir I would have to agree with you.... I was dubbed at the last GM garage/shop.... I am hoping that a trip to the local GM shop with the service bulletin I have may produce some positive results.... They have a few senior guys who like yourself, have done this for years... We will see... Thanx for the info...
