Also, fill out your sig. We have no idea who you are, or where you are located.
Checked the DIC codes by turning key to on but not starting. Hold options button and press the fuel button 4 times within 10 seconds or so. Then you can manualy go through the codes with the options button. In my case I had the code C1214 which is almost always EBTCM fatal. Removed it per instructions from the forum and had it rebuilt by module masters but is cheaper repair by ABS fixer. After repair, no more C1214.
I think this happens to most c5s.





Take a look below and see what you need to do to read your own DTCs
YOU DON'T NEED NO STINKEN CODE READER!!!!!!!!!!!!!

Go to “technical data base” and then to “Corvette ECM Computer Codes”. Then select your year car. Read the instructions and then scroll down to the "READ MORE" window to view the code definitions.\
Here is another very good site:

Make sure to include the H or C suffix!!
The Diagnostic Display Mode is entered with the following procedure:
1) Turn on the ignition but don't start the engine.
2) Press the RESET button to turn off any warning messages. (i.e. door open, trunk open ect)
3) Press and hold OPTIONS
4) While holding OPTIONS, press FUEL four times within a 10-second period.
Initially, on-board diagnostics go into an Automatic Mode which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each. ( i.e. PCM = 4 codes)
If none are present in a given module, you will see No More Codes on the display.
There are two kinds of diagnostic codes, Current and History designated with a letter suffix, C or ;H. A current code indicates a malfunction is present in the module displaying data. A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes.
More likely it's an indication of an intermittent malfunction.
Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.
Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except E/M. Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present;
press GAGES to go forward or FUEL to go back.
To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press RESET
To reset the codes once in manual mode, press and hold RESET until it displays NO CODES Press OPTIONS to go to the next module. Repeat the steps until you have reset the codes in all the computer modules.
NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles.
Once you have the codes, the next question is: What to do with the information?
First, consult the factory service manual. Any serious C5 Do-It-Yourself owner should invest in the Corvette Service Manual of the appropriate model year. The Service Manual is really a requirement if you want to understand and work on your C5.

Previous treads on the forum will give you a couple of things to check before you get to the EBCM. When I had the service ABS message, I also had the C1214 code. The C after the code indicates that it is a current problem. After checking the grounds and connections, I ended up sending the module to module masters for repair. ABS fixer is the cheapest route. All the info on how to check thinks out and how to remove the module for repair can be found on theis forum using the search key. If module is failing, much cheaper to remove asend out for repair. ABS fixer used to be $150 plus shipping.
Search the forum on C1214 and good luck.

. but never hurts to look some more...

if you want some piece of mind redo the chassis grounds.
GM did with the C6, thats gotta tell ya sumthin' 
and............read ALL the stickies at the top of the C5 general forum
..then you will be a corvette genius!

Just hold on a second! There can be other things wrong in the system that will set this code. There are other things to check per the service manual. It may very well be a EBTCM, but there are things to check to be absolutely sure. Don't tell this guy that his EBTCM is bad when you have not suggested the full troubleshooting procedure. I hate when people do this to guys that need help

I hate when someone with 300 post goes on an attack. This is the SECOND post that you have had issues with how I interface with someone. If you don't like what I have to say, just add what you have to say.
I've been a member of this forum since 1999 and have over 8000 post. If you want to talk this guy through the entire EBTCM troubleshooting procedure, be my guest. Then you can tell him the send his EBTCM out for repair.
The relays inside the module are junk! Sending it to ABS fixer resolves this issue. There are HUNDREDS of EBTCM post on the forum archive. Give the search thing a try. It works very well. Probably 3/4 of them are 1214 issues.
Im quite sure that I have typed out the entire EBTCM troubleshooting procedure at least ONCE. 
If you really want to help the OP, tell him that not only does he loose TRACTION CONTROL but most importantly anti-lock braking and Active Handling.

I will not get into the peeing contest. Both have their points. I have just one recommendation. Forget the code reader. All it can check is engine codes. There are few engine problems on modern cars. Most of the problems on the C5 and other modern cars are going to be called out in the proprietary sections of the codes. With the C5 you are fortunate GM provided the ability to read them. It is the only car built by any mfg that allows you to see the proprietary codes.

Heck, I suspect Bill Curlee has at one time disassembled his C5 down to the last nut and bolt as I have seen him post pictures of parts you wouldn't even know are on the car .....
