    Question ASR Trouble Code Question for the pros

    Ok well here is where I am at, My "ASR OFF" light is always on and the asr switch does nothing. Had my buddy who is a mechanic hook up his super expensive diagnostic computer and found the following #'s and info -

    C1214, C1215, C1216, C1217 - All of them said something like this "Electric Brake Control Relay Circuit Open", "Always Active", etc

    Where is this brake control relay located? Would this be as simple as trying a new relay or something of the sorts? I am trying to use my factory service manual with no luck. Where is this relay at or what should I do next? Thanks for the help.

    Those codes do not show up in GM service information. Make sure they are correct, because according to GM, they do not exist. Is this for your 98 SS?

    I noticed that while looking them up in my manuals. They were from his huge pcm reader thing. I am just curious as to where these relays would be. I know the numbers might be wrong, they might have been a listing of how many times the code was actually thrown. I believe it runs a test on each startup on the system. Where can I find the relays though and check/change them out. Also even a ground for the system, where would that be? Thanks

    I can't find that information... the real codes would be helpful if you can get them. But 9 times out of 10, any ASR problems usually co-exist with wheel speed sensor issues. Either with the sensors themselves or the connectors.

    I'll keep digging for you.

    Thanks for your help. He said it would have said if a speed sensor would have been the issue. It kept saying something like I said in the earlier post, relay issue, ground...

    Ok... not having the greatest luck. See if you can get the real codes for me so I can look them up!

    Can somebody who has dealt with this system tell me if any relays exist in it?

    According to the lovely GM service info, all relays in the ABS/TC system are internal to the EBCM or the BPMV. So no way to test them. The circuit open could mean hundreds of things without the right code with it.

    Interesting, so technically it could possibly be the entire ebtcm...

    Would the abs be having issues too if the whole control module was broken? How is it just limited to the asr? I know u need the codes, but I'm just curious about this...

    It is possible since both the ABS and ASR work on the same circuits and modules.... so to speak... but yes the ABS could very well be having issues if the ASR is. What makes it limited to just the ASR.... I have no idea.

    Is there a box under our car that runs this system? I know the one under the hood, but what does this drawing represent? Thanks!

    Click for full size
    1 is your ABSpump/ECBM computer
    2 is mounting bracket
    3 could possibly be SDM but i am unsure
    4 & 5 are speed sensor harnesses

    the EBCM/BPMV electronic brake control module/brake pressure modulating valve

    is the brain and fluid control , and is vehicle specific. to a point.
    how long has the ASR not worked?
    have you done any work on the abs or the rear end latly?
    is this the original ABS/ASR setup on car? ie.. no mods?
    is the ABS light on as well? or just asr off?

    nuff questions for now

    The abs/asr system is all stock, no changes. I have not done any work anywhere recently. The "ASR OFF" light kicked on last year before I put it away for the winter, its been on for about 1 week of driving this year. It has never gone off then come back on, its just been always on since the problem started. The "ASR OFF" light is the only one that is on, no abs lights or check engine lights.

    Disconnect the wire plug from the back of your ASR switch and then plug it back in to see if that corrects the problem.............

    sounds like you have a problem in the EBCM
    double check your fuses and the connections at the abs unit under the hood
    if all look good you probly need a EBCM
    GM wants huge $$$ for one
    i got one off EBAY for a F-body junkyeard and paid like 50$ ,worked fine for 2 yrs untill i sold the car
    but you have to find an ebcm for your yr w/ASR . no hard, just have search a little
