Need Help: Svc Active Handling - Service Traction Control
(2001 MN6 36000mi) all has been normal until now but this morning when I started the car the DIC scrolls "Service Traction System" "Service ABS" "Service Active Handling"
Any help would be appreciated.

1) Turn on the ignition but don't start the engine.
2) Press the "RESET" button to turn off any warning messages
3) Press and hold "OPTIONS"
4) While holding "OPTIONS", press "FUEL" four times within a 10-second period.

You may want to read the sticky about electrical problems and clean up the ground points before embarking on trouble shooting the ABS/Active Handling.
That is as long as its not causing drivability problems, if its engaging and causing driving issues then take it to someone right a way.

Do a little trouble shooting and check your grounds and then if you are still having problems you may need to replace the EBCM or have it rebuilt. If it comes down to a failed EBCM then I would recommend rebuild vs. replacement, unless your car is under warranty.
My EBCM failed and my car was out of warranty. After checking all my grounds as recommended in Bill Curlee's sticky. I came to the conclusion that it had to be a failed EBCM. I contacted one of the, several, companies that rebuild EBCM's and ask them if it wasn't the EBCM would I still have to pay for the rebuilt. They told me that they bench test it prior to making any repairs and if everything was fine my charge would be $50 plus return shipping. It turned out to be the EBCM, they repaired it and returned it in 4 days and gave me a lifetime warranty. It has worked flawlessly for the last year.
Good Luck!

It's a faulty EBCM with Code C1214 (most likely)
Ajay, PM me your email address & I'll send my "how to check & fix this problem" file with photos... here's the intro:
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 is in a large emailable file...LET ME KNOW IF YOU WANT, Bill

Well,
I dropped my car off at the dealer day before yesterday. I got a phone call from them yesterday telling me that they are replacing both the EBCM and the BPMV under warranty.
The service manager then said " I don't know what you paid for your GMPP but you definately got your monies worth"
The bill to get my car back would have been $3300.00 !!!

Hi 'trussme', I noticed that you have quite the knowledge about this abs/service traction control electrical issue. I just purchased my beautiful '03 vette a few months ago and now I have the notorious 'Service ABS, Service Traction Control etc' message. It is not engadging nor effecting my driving in any way so I am assuming it is the common electrical problem. I ran through the steps above and recieved these codes:
28-TCS C1214 H
60-IPC B1527 H
A0-LDCM B2282H, B2284H, U1064H
A1-RDCM B2283H, B2285H, U1064H
Do you or anyone else know what these codes mean? Is it more than just an electrical issue with the EBCM? Could you please email me the large info you had originally emailed to AJAY, you can pm me for email! If anyone else knows anything else about this, please let me know.
Thanks a ton!

BlueCorvetteGirl,
You might want to PM trussme for the files. Also take a look at this website ....
http://www.absfixer.com/
Do you have an extended warranty on the car?? Can you (or someone you know/trust) work on the car? If so you'll find lots of info here on the C1214 EBCM issue. Seach for "ABS" and you'll find a ton of threads out there on this issue.

BlackZ06,
Thanks for that info. I want to figure out if thats the problem first, then go from there. If its any easy swap out of the module, I'll be estatic. I actually just moved to the area and don't know a good vette mechanic around here. I'm not expert, but can hold my own. I'll need to see what I'm getting into first before I go turn some wrenches.
Thanks for the reply!
