service active suspension soon
today i had the warning light and "service active suspension soon" . I realize that could be an entire host of problems. just wondering what the most common problem may be.

It's a very "common problem", many C5's have:
Let's cover some basic information on AH, TC, and ABS. In simple terms, these three systems combine data from wheel speed sensors, yaw rate sensors, steering wheel position sensors, along with brake and throttle inputs to determine what the driver wants to do and detects any lose of traction and take corrective action by pulling back on the throttle, activating brakes on individual wheels, or releasing brake pressure as needed to maintain traction.
What goes wrong
When there is a problem anywhere in the system, the computer does not know what's going on with the car or cannot respond correctly. Rather than risking the wrong response which could potentially wreck you car, the whole system is simply disabled for the remainder of the ignition cycle. At this time you will see the ABS and Traction Control warning indicators illuminated on the instrument cluster along with the following messages on the Driver Information Center (DIC):
- Service ABS
- Service Traction System
- Service Active Handling
At this point, you can safely continue to drive your car, just remember that your electronic driving aids are no longer functioning so you should adjust your driving habits accordingly.
Troubleshooting
As I said before, when there is a problem the system is deactivated for the remainder of the ignition cycle, so sometimes everything will go back to normal if you just turn off the car and restart it. If that corrects the problem, it was either a glitch in the system, a lose connection that's going to come back soon or an early sign of a future failure that is coming. Even though the system is now functional it is still beneficial to continue to trouble shoot. The history code should give you a good idea of what to check
The next step is to see where the fault is. If you have several different codes write them down, clear them, and see which ones come back the next time you start the car. At this point, I'm betting that the codes point to either the EBCM or the wheel speed sensors. We'll get to the wheel speed sensors later, for now, let's get to the EBCM.
Electronic Brake Control Module
The most common code for the EBCM is C1214 - Sol Valve relay Contact or coil CKT Open. This code is set when the system voltage is less than 8 volts for 0.23 seconds. Since our goal is to fix this for the lowest price possible, we'll start checking things we can fix for free
.....the rest of this large file needs to be emailed (has photos)...so, if you want it, please P.M.me your email address & I'll get it to you. Bill

Did you get
SERVICE RIDE CONTROL
or:
SERVICE TRACTION SYSTEM
SERVICE ABS
SERVICE ACTIVE HANDLING
If you got the ride control message your car has the F45 or F55 suspension and it needs servicing. If you got any of the others then the problem is POSSIBLY in the EBCM.
Dump the codes from the car to see what the real problem is ... go here to learn how to dump the DTCs.

Post the DTCs in this thread and someone can help you diagnose the problem.

I don't know what happened to the previous message I sent to you. Please send me the rest of this file, I have a 2004 C5 coupe with 121,000 miles on it and I am getting the service ABS, TC and AH messages on the DIC as well as the "idiot" lights on the console. My email is ltesc@sbcglobal.net. Thanks, Luckstr
