Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message

[Stoneage_Caddy]

im trying to find it ...alot of the stuff is missing right now

basicly a relay is wired into ckt 370 red at the module in the trunk ...with the key on the relay is energized and one side of the circuit is grounded ....you may also need to adjust the iso8 setting int he ipc overirides like i had to ....

all the info is here somewhere on my computer ....problem is i got a new computer since i had been thru this so its in a file on this computer marked "Dell" ....itll take some digging

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?

I have just purchased a 1991 Deville with 75k. All is good except the rear struts are fully inflated which causes the rear to ride high. Can someone please advvise what I should do or check for?

Thanks,
Chris

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?

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

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.

Hey Guys I have a 97 sts ...for the longest time ..When I would hit a bump my stability warning would come on and my abs and trac contor lights would come on the dash ......So I went and looked at the front end conections from the speed sensor ...now the warning lights will not go off ....so I checked the speed sensors with a ohme metter and the are ok ...But when I read the codes it is telling me that my letf front and right rear is not working ...Now my question is are they both on the same circut ? any help on this would be great cause it's driving me nuts

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?

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).

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?

[Soxxman]

What symptoms were you experiencing & what year & model is yours?

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.

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
