Service abs and traction control code?
I have a 03 and it is coming up with the code as per title and on the dash, also the icon ABS, and the icon with back of the vette showing rear traction swirl mark. Does anyone know the fix, or do I just take it in to the dealership. I am also concerned about the tune I had, and do not want them to mess up the program. Anyone have this happen to them? Thanks so much in advance for your advice or knowledge. Hot Rod

Push reset a million times on the DIC controls, really just three or four, then turn car off, restart, repeat! Chances are it will go away. It has happened to me a couple off times in almost two years of ownership!

There are 3 major elements; the Electronic Brake Control Module (EBCM), the Brake Pressure Modulator Valve (BPMV) and the wheel sensors. All can go bad and the parts are pricey. C1214 was the code I got and it turned out to be bad voltages on the EBCM. Dirty grounds have been known to cause problems too.
The EBCM change doesn't need a reflash. Its an electronics box change so it wont disturb other systems. Your tune should be good but warn the dealer not to mess with it.

EBCM Advice

.... 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.
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.

Here's what you need to know & if dealer will replace it "n/c" under warranty plan..get it done (otherwise PM me for complete file on how-to-do-it yourself):

Just got call from dealer. They are ordering an EBCM for the ABS and active handling error messages. So hopefully I will have her back tomorrow. But they also have to check out a leak i have in rear diff area. So I probably won't see my car till at least thursday.

I had the EBCM replaced this weekend. That was way too expensive. It was the first repair I had to have done on the car. If this is just the beginning it may be time to start thinking about an upgrade to a newer car.
