    Over the weekend the "Service 4 Wheel Steer" came on the instrument panel. I don't have a check engine light on but I presume it *may* throw a code?

    Anyone know the common causes for this? What are the steps I should take here...

    I'm in the same boat...

    My 03 Sierra Quadra has the "Service 4 Wheel Steer" come up on the instrument panel and it's locked in 2 wheel steer.
    I'm soooo bummed, I love my "JoeBerben" and really need it fixed. I don't know anyone qualifed to do the work.
    I live in Rancho Cucamonga, San Bernardino, CA.

    All the best,

    unfortunitly thats not something many of us (almost all of us i think) have played with, ive only seen one truck ever in person with it, and have never driven one.

    dealer or a good trusted mechanic would be all i could recomend.

    I ended up doing it myself, I was able to get a deal on the QS-motor from the dealer... Was really simple to replace, if I recall it was something like 8 little bolts and 2 electric housing clips. Been doing fine since!

    Occasionally the light will come on, and then go back off. Generally this happens if you grab the steering wheel at startup.. I believe it throws off the calibration at startup... As I'm closing in on 200k miles... I've asked a friend who deals in trucks to keep his eyes out... Man I love this QS, too bad GM ruined the marketing of it...
