hello all! i joined this forum to see if anyone had any luck solving the service ride control problem! i too have a 1994 sedan deville with the same error message. i am wondering if it is telling the truth and if the problem could be a crack/leak in one of the hard plastic air lines that go to all the struts? i am going to check all of my lines tomorrow and will let you know what i find. those hard plastic air lines vs soft rubber hoses are very prone to breakage with age. does this make any sense to anyone out there?

thanks all!

no , there are only 2 air lines and there for the rear shocks , pull the rear wheels and check them if you wish but most likely your struts are dead ....the lines are pretty stout i doubt there bad ....

I just read through this whole thread and see a glaring lack of information on the 93 N* seville. Every time it was asked about no useful answer was given. The TSB specifically excludes the 93 N* seville.
obvious reason for my Gripe, I just converted my front struts to passive and cut the wires to the struts. now my "service ride control" message pops up every couple of minutes. my rear struts haven't been replaced yet (too $$) but they will be in the future.
How can I shut up this bleepin' computer!!!

oh and for the record the passive struts that monroe and delco show for the rear are wrong (71854, 801854 and 503-343) for the 93 n* STS

I just bought a 94 sts a few months ago. It to has the "service ride control" indicator lit up. The car is in excellent condition however it has 194,000 miles. I bought it from an old man and women and it was a 1 owner. The car has been very well maintenanced and garage kept. Honestly I could care less about the indicator light. But the car rides horribly. I read this forum to start to finish, I checked my codes and tested my air compressor (it seems to be working). After reading this from start to finish I think I know whats wrong with my car. I think it is stuck in soft mode. The back looks as though it sets to low and on ruff roads it rides like a log truck. After reading all this I realy don't want to go to a dealership just to get told I need new shocks and struts when that might not be the case. I just want my car to ride better!!! I am no mechanic by any means. I'm a 25 year old college boy in Atlanta GA. Can someone please tell me what other things I can do to find out exactly why the car is riding so bad or a way for me to know for sure if it is stuck in soft mode or if in fact my shocks and struts are bad? If they are stuck in soft mode, will just changing a sensor or module fix that? Please Help! And here are my codes.

Info -- Procedure to Disable Illumination of Service Indicator AFTER installing Passive Struts #00-03-11-001A

Applies to:
  • 1989-1992 Cadillac Allante
  • 1991-1993 Cadillac Eldorado, Seville
  • 1991-1995 Cadillac DeVille
This bulletin is being revised to clarify when this bulletin may be used to turn the service suspension lamp off. Also, a step has been added to the 1991 Cadillac Eldorado and Seville repair. Please discard Corporate Bulletin Number 00-03-11-001 (Section 3 -- Suspension)
Some owners may bring their vehicles in for service with an illuminated service suspension light. The service suspension indicator lamp is telling the owner that the vehicle is due for strut/shock replacement, a maintenance item. The customer may elect to have passive struts installed in their vehicles due to the repair cost savings and/or parts availability. The installation of passive shock/struts will result in handling characteristics which are the equal to a like vehicle without the computer controlled ride, with all other components such as tires, tire pressure, springs, etc. being equal. The installation of (4) new passive struts will cause the continued illumination of the service suspension indicator. If desired by the customer, the service indicator may be disabled AFTER THE INSTALLATION OF THE (4) NEW PASSIVE STRUTS, using the appropriate service procedure listed below. This bulletin DOES NOT authorize this procedure unless (4) NEW PASSIVE STRUTS WERE INSTALLED ON THE VEHICLE.
The wiring harness going to each strut and or chock assembly should be cut and taped back to clean-up the appearance both under the hood and under the vehicle. In addition, each specific vehicle will require a modification as outlined below:
  • 1989-1992 Allante with Speed Dependent Damping (SDD): Refer to the Service Manual page 8D-13 (1989) or 8D-14 (1990-1992). On these vehicles, adjust the BCM Override value "BS08". To do this, use the warmer/cooler button on the CCDIC to decrease the BCM override value "BS08" which is displayed when you enter the system by two(2). When the desired number is displayed on the CCDIC, it must be stored by holding the "Elapsed Time" and "Fuel Used" buttons until the new value flashes on and off. When it flashes on and off, the new value has been stored.
  • 1991 Eldorado and Seville with Computer Command Ride (CCR): Refer to the Service Manual page 8D-12. Set the BCM override value BS09 to 0 by using the warmer and cooler buttons. Store this value by pressing the Econ button on the climate control panel and the Instant Econ button on the Fuel Data/Drivers Information Center for about five seconds. The new value will be stored even through the indicator does not flash. Remove the key from the ignition. Disconnect both battery cables from the battery. When both cables have been disconnected, touch the ends of the cables together and hold for five seconds. This will discharge the capacitors in the system and allow the system to perform properly when the battery cables are reconnected. Advise the customer they will have to reset all radio stations and clock.
  • 1993 Eldorado and Seville with Speed Sensitive Suspension and 4.9L Engine Only: Refer to page 8A-43-6 in the 1992 Eldorado Seville Service Manual.
    • Cut Circuit 1020 (PINK)
    • Attach the IPC side of circuit 1020 to relay pin 87A
    • Attach the module side of circuit 1020 to relay pin 86
    • Run a ground wire to relay pin 30
    • Run a wire from a switched ignition (hot in run) source to relay pin 85.
  • 1991-1993 DeVille with Computer Command Ride (CCR): Refer to the Service Manual, page 8A-43-0. Cut Circuit 1300 (Dark Green wire) at the CCR module (Pin C15) to disable the indicator lamp. Tape the wires back into the harness to prevent shorting to other components.
  • 1994-1995 DeVille with Speed Sensitive Suspension (SSS) and 4.9L Engines ONLY: Refer to the 1994 Eldorado, Seville, DeVille Service Manual, page 8A-43-14:
    • Locate and cut circuit 370 (RED)
    • Attach the IPC side of circuit 370 to pin 87A of the relay
    • Attach the module side of circuit 370 to pin 86 of the relay
    • Run a ground wire to relay pin 30
    • Run a wire from a switched ignition (hot in run) source to relay pin 85.
  • The following part numbers are required to make the correction on the 1993 Eldorado/Seville and the 1994-1995 DeVille:

FYI the above procedure worked like a charm on our 94 Deville with 4.9. There is no need to get the GM parts listed above. I got a $4 generic relay at the parts store and it worked great. It is very easy to do this install. It took me about 15 minutes. Here are more details in case anyone is interested:

Parts needed: generic relay (most have the same numbers as in the above directions: 85,86,87a, 30) . The relays are on the shelf near the fuses at most parts stores. Some quarter inch female terminals, a couple of feet of 16 or 18 gauge wire, two splice doohickeys for tapping into wires without having to cut them. A couple of small wire nuts.

1. Locate the module in the right rear compartment of trunk.
2. Locate three wires: Red (circuit 370) I think this is C15 on the plug, Brwn 12 V ( C16)this is near the red wire and black ground (D15) is also near the red wire. The shop manual 800-43-14 shows the diagram with the correct labels.
3. Wire the relay as described above. you only need to cut one wire, the red one. The black and brown can be tapped without cutting.
4. After wiring is done you can attach the relay to the board with a small screw, there are several locations for doing this.

That is it. All this does is force a polarity reverse for the red IPC circuit. When the module tries to ground the red wire to send the SRC message, this relay is energized and forces an open circuit. I wish we had done this 3 years ago. It is so nice to not see that annoying message, no more having to push the information button!

Well, here's my $.02. I happen to work at a Cadillac Dealer doing steering n suspension. The code doesnt really mean much. You are suppose to ground terminal c to ground and count the # of flashes on your ride control module in the trunk. Very simple. But anyways. You cant get OEM parts forthis car anymore. But you can get a Bypass kit. YOu wire it in the trunk inline w/ your ride control module and the light will never come on again. As long as your car doesnt ride bad its probably just the electronic part of a strut that has went bad. Someone may have already said this but there were to many replies to your question to read them all.

Sir, I'm very interested in the three trees that you make reference to, but when I tried to go to the web sites you listed they were not there or have been moved somewhere else. How could I obtain copies of the documents that show how to defeat the "Service Ride Control" on the LCD? Thank you for your assistance.

I'm glad to see there is a solution out there but does anyone have any details how to do the same for the '98 STS? I just ordered a kit from Arnott for my front struts but if there is a fix I can do I will get the backs from a local dealer.

Hi, all. This is my first post, and I appreciate this forum already. I have been reading all over the place, but still have a question: At the end of this post is a portion of a service manual that applies to my 92 Eldo TC. I want to disable the Service Ride Control message, constantly on for 4 or 5 years.:eek:

What I need to learn is how to correctly use my OBD to follow the below directions. Cad models have different codes and button-pushing sequences, and I couldn't find specifics for my Cad.

I would appreciate any direct advice or guidance to available reference materials.

Thank you.

OK, Ive read so much on replacing the electronic stuts with passive ones, but here is one main question for my 93 Deville, Monro makes replacement ones for about $80 each. Strutmasters and arnott have them for about $140 each, bottom line, won't I still get the bouncy ride if I have adults in the back with the passive struts - thus the more weight in the back seat and trunk the more bounce from passive struts?
