    I have a 94 Eldorado w/ the Northstar, and get the same message. How do I check the ride control box? It said in earlier post to ground the "c" pin, to be fair i havent looked at it yet to know but is "c" labeld on the module?

    Re: Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

    I've got a problem I hope someone can give guidance on. I have a 95 Concourse and just went to passive struts on the front. The shop who did the work installed the resistor that came withe the shocks and now I get the "Service Ride Control" message after a couple miles of driving. It will go away if the car is turned off, but will then return after a few miles of driving.
    Does any one know of a way to eliminate this?

    Re: Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

    your problem is that it's seeing data from 2 corners and 2 are dead

    you should have resistors at all 4 corners. that will eliminate your light

    Re: Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

    I just fixed my SRC message. I ran the codes and got S061 and S063. I ordered 2 height control sensors from a junkyard, snapped them in and no more problems. I just thought you'd like to know that before you do the disable proceedure. They were fairly easy to put in. Just gotta use your noggin! In the case that I might need new struts, I would consider the passives and do the message disable proceedure. If it could be fixed for $150 like mine, I'd rather have the electronically controlled ride.

    Re: Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

    This thread is insane. It's dedicated to fixing the common Service ride control message but there isn't a single clear cut post on how to do this. Some say do a resistor thing, others say swap out struts. I want to change out my struts but the closest cadillac dealership doesn't do it anymore. I don't have enough skill to rip apart this and that and be able to put it back together again. Does anybody know a reliable suspension person in the D.C. area that knows how to do this?

    Thumbs down Re: Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

    I also have that "service ride control" on my display.

    I have a Cadillac STS 1994 with Northstar 4,6 L engine
    Original, but Europe sold so I have km/h instead of miles
    and Celsius instead of Farenheit. I guess/think but I'm not shure,
    that those cars that were shipped to Europe had harder suspension
    springs ???

    If I press "red" (warm) button and "off" buttom I have these codes:

    P052 HISTORY
    P061 HISTORY
    P062 HISTORY
    P071 HISTORY
    P091 HISTORY
    P109 HISTORY

    NO IPC CODES
    NO ACP CODES
    NO SIR CODES

    T072 HISTORY
    T073 HISTORY

    S015 HISTORY
    S016 HISTORY
    S018 HISTORY
    S036 HISTORY
    S044 HISTORY
    S061 HISTORY

    What does all these codes have the word histroy behind ?
    What does all these codes mean ?
    Is it good or bad to not have any codes on IPC, ACP and SIR ?

    Looking forward to solve this. Thanks for the time you lay down trying to help me (and others with same codes).

    Re: Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

    It sounds like I have the same issue you have with my ’94 Sedan DeVille. When checking my code it also read Code IO39. When I took it to the dealership they said I needed all 4 struts & shocks replaced and a relay. I am getting the Service Ride Control Alert, and when I drive over 15 miles per hours I hear a noise on the left front of the car that tends to get louder when I turn or the car shifts. It is a dull groan. Does this sound like a similar description of your problem? And what did you finally find out?

    Re: Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

    I have a 96 eldo with 70k and been seeing this message for a while now.. it seems to come up when i take off fast and sudden braking.. i guess the suspension is getting softer as well.
    I think i'm just going to replace the suspension and by-pass the signal..
    I know there is a how-to but the links are no longer good since this thread was started in 2003.. maybe someone can post up some updated info.
    If i find some info that is updated i'll post back.
    Thank you.

    Check the codes before doing anything.

    Wink Re: Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

    If anybody is still wanting to know,

    On a '94 4.6L Seville, with 2 wires on the struts, a fuel injector wired inplace of the strut wiring will fool the computer, the "Service Ride Control "goes away.

    I personnelly did it last night and it works.

    FYI
