    Bad sensors and steering became difficult

    My Traction control and ABS lights have been on for a while. just yesterday my Brake warning light came on as well, the red light that looks like this (!) as soon as this happened it became difficult to steer the vehicle. I checked the power steering fluid and it looks pretty black and it appears there may be a slight leak but there is still plenty of fluid in the system. I was wondering if the sensors could have anything to do with the difficult steering or if the contaminated fluid itself could be the problem? or perhaps maybe the pump is going at this point. Have any of you experienced this issue? any help is appreciated.

    Ahh, sounds like you have the speed sensitive power steering.

    What you're experiencing with the stiff steering with the brake light on is normal. So fix your brake issue and you'll get the power steering back.

    I removed the 30amp ABS fuse a couple months ago. All three of those lights came on and I lost power steering. Put the fuse back after a few days and everything back to normal.

    Re: Bad sensors and steering became difficult

    Okay. I did a Scan on my vehicle today and found the following errors. " U1040" Lost connection with Electronic brake module. My EBCM either needs to be serviced or replaced. Which has nothing to do with the bad wheel sensors I was talking about above. Has anybody had this same issue? was your EBCM repairable or did you have to replace the whole module. What was the cost of this repair or did you do the repair yourself? I am leaning towards replacing or repairing myself. any advice would be great.

    Hello kylebooth,

    I apologize that you have these concern with your EBCM. I do see that you are located in Canada. Have you attempted to reach out to GM of Canada regarding this concern if you are planning on working with a dealership? You can reach out to them on one of the methods listed here: http://www.gm.ca/gm/english/corporat...actus/overview. Please keep us updated if you do plan on reach out to them regarding this concern. I will be on the lookout for your future messages.
