Speed Sensitive Suspension and the "SERVICE RIDE CONTROL" message - Page 6

Hello,

I am not sure how much the CVRSS system changed between 2000 and 1997. I would suspect that the resistor trick should work. To be sure, try to locate a copy of the service manual and go to the troubleshoot section for the CVRSS struts. An acceptable range of resistance values should be in the table. Alternately, you could disconnect one of the struts and use a multimeter to measure the resistance directly.

If the resistance is ~12 ohms, chances are it will work. At least it shouldn't do any damage. If the number is significantly different - all bets are off.

Thanks a lot, May Dog. I ordered the resistors yesterday, so I'm going to give it a shot. From there, I guess I'll find out if: the position sensors will cause the system to look for different resistance values based on movement, the rear seeks the same resistance value at the same height, etc. Basically, I want the car to think it's always on a perfectly flat surface and remains happy with that. I'm no hotrodder but "Speed Limited To 90 MPH" just doesn't work for me.

Just a sec, are you having a problem with the strut "sensors" or the ride height sensors? I had assumed that you were asking about the strut sensors. The ride height sensors are a different animal. You can fool it by feeding a 2.5volt signal info the sense line. Just divide the 8v regulated supply or use a zener as some other folks have.

What do you mean under "funny noises"? It’s possible all right. Every time in ~ 20 sec after you turn on the key, RSS make self diagnostic and you SHOULD hear air compressor running for about a sec, and then you SHOULD hear air exhaust when it opens valve. No point to change air compressor if you hear all that.

Please send me the PDF's

Thanks, again, Maydog. I was talking about the strut sensors but I'll keep the ride height work-around in mind also. I got the resistors for the struts a few weeks ago, just haven't had time to try it out. When I finally get my procrastinating ass around to doing it, I'll post the results.

I have the "service ride control" message + code I039. I have found Boston Struts on the web and they say they have a fix. Can anyone advise on this or has anyone used these products.

Stoneage_Caddy · #83 (**permalink**) 07-17-05, 02:07 PM

i used the product , its ok ...what year car do you have ?

A year ago I had bought all four shocks and struts for my 95 sedan deville. four months after installing the front struts, they were very harsh, it caused the radiator and other parts to break. I call Denis of Boston, he advised me to buy new softer springs for my front struts, the ride got better for the first three months, now, it's harsh again, but not as before.

Cadillac dealers sell shocks and struts that are not expensive and for the same price as what Boston is selling, you might want to check with them first. do not rush and get boston, I have no problem with the air shocks.

this link does not work,,is there another 1 or can anyone tell me what it is?
Thanks,

It says only to do this when switching to non electric struts but if you feel your original struts are OK it still works and you can keep your original ones.

do you have a link that talks about a 1995 SLS?

You know I've read this post from beginning to end and I still do not see a clear cut procedure to fix this error message on the screen. Bypassing relays to adding resistors to changing struts. Has anybody actually fixed the problem on the 4.9L engines?

I have a 91 Coup Deville with 21300 miles. I have not liked the ride since day one. So while at the dealer about 3 yrs ago I mentioned this during a routine checkup. The service manger (Kuni Cadillac Portland ,OR) said we can re-program that for you!!! Best thing I ever did. Now I on the high setting all the time,,,yet it still keeps all height adjustments etc. I told the service manger that I had no idea why anyone would want those two other settings. He agreed,,,but said women love it.

My 1992 El Dorado (not Northstar) is also displaying this message. If the ride, which absolutely wallows, is any indication it may be that the struts are worn out. The car has a little over 100K mile on crummy roads. Does the solution of replacing the struts with static ones apply to this car? If so, could someone make a recommendation on the best ones that won't land me in bankruptcy court?
Thanks!

On my 02 Escalde, I had the rear dropped 3 inches and the front 2. I did this a few years ago and was told that there was a work around for the service ride control light. After about 8 months, of hearing about this fix, and this new product, I said screw it and went back to the stock ride height with stock suspension

because nothing worked. Now this is a bit different than your situation, but it was a process that I wish upon NO ONE!

I know GM did not have a buypass, I know no one locally could beat the system, and I know we tried a few different products with no luck. I do not know how much things have changed since this was back in 03, but it sucked. Every so often the light comes back on, but after I shut the car off, it resets itself.
