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

My cadillac escaped is showing the service battery charging system my truck turns on and after i turn it off it doesn't turn on anymore what could it be any help would be good

What year is your caddy ? Given the amount of electronics on these vehicles it could be a lot of thing's ! Are there any lights lit on the instrument cluster ? check engine , security etc.. The charging system on your caddy is computer controlled an if it is showing a service battery charging system warning message there are DTC'S stored . This is one your going to need to take to a dealer , do you have Tech 2 scan tool to hook-up to the vehicle ! It could have an ignition switch problem , power mode miss match ! All the modules on this vehicle communicate on a data bus, serial data communication . class 2 ,C.A.N -controller area network ! When you turn that key to start the vehicle ,the ignition switch sends a discrete voltage input to the BCM -body control module ,which in turn energizes relays that powers up systems on the vehicle ! So do yourself a favor before you make it worst !

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.

I have a p0008 code & I'm worried

P0008 CADILLAC - Engine Positions System Performance Bank 1
The ECM detects that both camshafts on either bank of the engine are mis-aligned with the crankshaft for more than 4 seconds or a cumulative of 50 seconds.

The Engine Control Module (ECM) monitors the position of both camshafts and the crankshaft. The ECM performs a test for misalignment between both camshafts on one bank of the engine and the crankshaft. During the test the ECM learns the position of the camshafts and the crankshaft. While the engine is idling, the ECM compares the position of both the camshafts and the crankshaft with the learned value. The ECM will set the P0008 code if both learned values for one bank of the engine are exceeding a calibrated threshold in the same direction.

- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Engine mechanical problems
- Incorrect timing chain
- Stretched timing chain
- Failed camshaft actuator or actuator solenoid

Tech notes
There is a factory service bulletin for the following Cadillac models:

2004-2008 Cadillac CTS SRX
2005-2008 Cadillac STS

The service bulletin suggest replacing the primary drive and both secondary drive timing chains. Contact your Cadillac dealer for more information. The repair could still be cover under factory warranty.

Hope this helps (remember to rate this answer).

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.
