Ok this is the module to control the electronic suspension
jusk ask for the suspension module to any yonk yard
or pick up part, but i have to tell you something a had a cadillac
giving me false codes information for the suspension and also i did had a message on the digital dash, since is been a few yrs since i fix it, i tough it said service ride control, any way the problem was a ground problem the thick ground wire going to the module was having a high resistance problem meaning the ground was poor, the solution i took was adding another grond from the car budy to the suspension computer ground i weld an extra wire and had to drive the car for a little while and that took care of the problem, and actually that computer was behind the rear seat but on the lugage compartment,
and if you want some wiring diagrams go the public library or
go to and buy the repair information from alldata for this specific car, it will cost you something but nothing similAR to the 1200 good luck and any more questions? feel free to ask

I have a Cadillac deville 1998 v8 northstar. I had my alternator rebuilt and got a new battery. Vehicle started once but dash read battery not charging. Took vehicle to O'Riellys Battery tested bad. H

When you replaced battery you activated the system. Need to read owner manual and see if it tells how to deactivate it. You may need to contact dealer to deactivate it.

2003 DeVille DHS rear suspension: what type of air suspension system is employed? My rear end is bouncing all over, especially when it's below freezing. Local shop says if it's air shocks repair will be...

A GM dealer can tell you if you give him the VIN number, but the simplest way is to check one of the rear struts for an electrical connection (will also have a leveling air line connection). If there is one, you have a road sensing suspension (RSS) with rear leveling capability - if not, just air shocks. If you have RSS, these struts are very expensive and notoriously unreliable, and you may want to replace them with air shocks. However, if you do this you will have to trick the RSS into thinking they are still there by terminating each electrical connector with a resistor (see the Cadillac Forums website).

I have a 93 caddy deville and cannot find a site to tell me what the codes mean

this site has alot of info:

Hope this is what you need!!!

ABS (Antilock Brake System)
AMP (Amplifier)
DDM (Door Driver Module)
DIM (Dash Integration Module)
IPC (Instrument Panel Cluster)
IPM (Instrument Panel Module)
IRC (Integrated Radio Module)
PCM (Powertrain Control Module)
RFA (Remote Function Actuation)
RIM (Rear Integration Module)
SDM (Sensing and Diagnostic Module) Includes airbag crash data. Under RF seat
VTD (Vehicle Theft Deterrent)
MSM (Memory Seat Module)
TTM (Tilt/Telescoping Module)
RSS (Road Sensing Suspension)

How To Pull Codes To check for Diagnostic Trouble Codes stored in the computer, turn the ignition on, then hold down the OFF and WARMER (for digital dash) or OFF and passenger-WARMER buttons (for analog dash) or OFF and "Info ^" buttons (if you have temperature dials) until all of the dash lights come on. The digital display will then show any codes stored. Be prepared to write them down. When it's done, you will probably see "PCM?" At that point, press the OFF button 3 or 4 times until the dash goes back to normal, or just turn off the ignition.

Not in owner's manual

Bring it to the Cadillac dealer and prepare for a huge bill. There is something wrong with the suspension system, and they are the only ones who can work on it.
