    Disabling hill assist?

    dunno if this was mentioned or not, but I have a manual with no CUE and I cant for the life of me find out how to disable that STUPID hill assist. I looked through the owners book and found nothing (am I blind?)

    anyways, is there a fuse? I looked for that to and couldn't find one.

    Re: Disabling hill assist?

    I know how Bendix's systems work and Ill assume these function on a similar principle - if so it is a function of the ABS controller/module and is thusly impossible to disable without removing the grade sensor (which would trigger a brake fault as it is used for rollover detection).

    Personally I don't mind it - I know plenty of Subaru/BMW guys (and truckers with class 8 trucks) that love the feature. Take the car to Seattle or San Fran and I think it'd be a godsend when you're tired.

    lol yeah I guess it would be a godsend on those grades, but I think the steepest grade around here is like... 25degrees? its just annoying having the brake clamp on the slightest incline, its just not necessary and drives me nuts lol

    I'm always amazed at how small the angle actually is on a road that looks like a huge hill: a 25 degree grade would exceed the slope of the steepest street in the United States. The street that tops the list here http://www.fixr.com/infographics/top...t-streets.html has a 45 per cent gradient, which would be an angle of around 23 degrees. An airplane on descent to a runway typically follows a 3 degree descent path, but most people on the ground watching one approach to landing will estimate the angle at much steeper than that.

    I appreciate the topic. Indeed people (including me) usually overestimate how steep something is. One correction: 45% grade is 20.25 degrees.

    Could be, I didn't put too much thought into the calculation; however, I made the conversion from the chart on this page: http://en.wikipedia.org/wiki/Grade_%28slope%29

    Regardless, I tend to agree with Steve on the HillHolder: I'm not a big fan.

    anyways, not to get into anything too deep about road construction or angles... I just want to get rid of that annoying wheel clamp whenever im on an incline lol.

    Good find for anyone wanting to permanently disable.

    Edit: Or maybe not. See below.

    Re: Disabling hill assist?

    Strange... I figured removing the grade sensor would do it... but I can't believe GM made a "dummy" grade sensor for automatic cars instead of just omitting that whole layer of the harness...

    Well - good to know.

    Re: Disabling hill assist?

    doesn't look like that will work for you guys
    might be worth trying though

    reason i say so is that after looking at the camaro part numbers (for the MT vs AT yaw sensors) and then comparing to the ATS yaw sensor part number

    there is only one ATS yaw sensor for both AT and MT cars unlike the Camaro that has two

    so... the question then becomes can you use the camaro part number and will that talk nice with the rest of the ATS systems?
    i doubt it ... but again it might be worth someone trying just to find out for sure

    What is so bad about the hill assist? I like it. This will also save wear and tear on the clutch over time.

    Also I've found that the softer you stop the less frequent the hill assist turns on. If you stop hard the hill assist activates, but if you barely come to a stop the hill assist doesn't grab.

    It does seem to take a little extra pressure on the brake pedal to activate it on my car. Soft touch, no clamp effect.
