Default EBTCM Error code C1255

I have a 2000 C5 Corvette, no active handling system, that is showing a Service ABS, Service Traction Control message on my dash. I pulled the codes and I am getting a TCS C1255 code which tells me that my EBTCM module is not functioning. I have called around and am also told that this part is difficult to get and will be costly. I found a company in California that will sell me a module for $1400. More research tells me that it appears to be fairly easy to replace. Are there any thoughts on this or recommendations?

Be aware that there are two different version of the module. On the module's bar code tag there will be a large V or M. If you get a replacement make sure you get the right version for your car.

Ok, thanks. Company is in California that has one for sale and they wanted the number off the module to make sure it is the right one.

I do not remember what all codes mine had but I cut the green wire that is the main power to the moon for and applied battery power to it for short bursts maybe a second or two long. I kept doing it until the motor sounded like it was free and smooth keep in mind you want to take it slow to not over heat any thing. This process took me a couple days just going and powering the motor but it is fixed now when I was done I just reconnected the wire.

C1255 is code of death. you can get a used one for much cheaper than 1400.00 for that price it better be new. the 97-00 ebcm are not repairable. i can get you in contact with the people i got my used one for 350.00 with a guarantee. no active handling is the code M.

Yes, mine is the M code version. I would appreciate any direction on where to go. I also need to find out if it needs programed to my car, or is plug and play?

Default ECBM for C5 Corvette

Thanks for the information. I will check. I have a new battery in the car, but will check the voltage at the fuse and post to post.

Here is a link for diagnosis of the ignition switch:

http://forums.corvetteforum.com/1568186703-post64.html

If the voltage at the indicated fuses is more than about 0.3 volts less than the voltage measured across the battery posts then the ignition switch may be causing a number of problems including the EBCM code.

You cannot use the dash gauges to determine the state of health of the battery. Those indicate the state of health of the charging system and NOT the battery. Since many sensors in the C5 go through diagnostics at key turn on time and BEFORE the alternator is generating voltage, voltage once the engine is running is TOO late to help.

Look in the back of your owners manual for the fuses for the EBCM......

Worth checking BEFORE you drop $350 much less $1400 on parts. JMHO.

This whole ECBM thing intrigues me. Why would Chevrolet allow a part as critical to the safety of a car be discontinued. Is there a chance that they would allow a 3rd party the design rights to make the part themselves. If not in a couple of years, we are all screwed. Who at Chevrolet would you contact to get such rights to make after market?

The aftermarket has the right to produce the part but there is not enough demand for them to invest in making it at this point most parts produced by the aftermarket fit multiple applications and the cost is feasible. In our situation we are a captive audience and there is nothing we can do about it

It makes no sense whatsoever. I've called the Executive Assistant to GM CEO Mary Barra about this demanding they look into it and take reasonable steps to fix it for affected Corvette owners. I feel its unacceptable. No response yet. If you or anybody else wants the phone number for the Executive Assistant, let me know and I will provide it.

They probably won't ever make this part again (and by "probably" I mean "no chance"). Because of the very small market for it, the complexity of the part, and the cost to engineer a replacement, don't expect to ever see this made again.

However, that shouldn't be the end of the discussion. Because it's a part designed for safety, the NHTSA and/or DOT should get involved and give GM a choice...make the part available or be willing to buy back Corvettes at fair market value if the part fails and no fix is available for this SAFETY feature. Leaving Corvette owners just sitting there with broken cars that can't be readily fixed is ludacris. I've bought 4 cars in my life...all GM (all brand new except my C5). My immediate family has bought about 15 brand new GMs. They feel this EBCM thing is ridiculous and none of us will ever buy a new GM again if they don't come up with something.

I was curious as what their response would be and the first canned reply was to talk to a dealership. The second after I told them the dealers cannot do anything was this:

Thank you again for taking the time to contact Chevrolet.
Typical GM.

Just curious...who did you call, email, or write to? Again, if you want a phone number and/or email directly to CEO Mary Barra's Executive Assistant to inquire about this, let me know by PM and I'll be glad to provide it.

This matter is laughable. A car manufacturer of GMs size just leaving owners of their "halo" car with no readily available option to repair said car if it breaks is pretty unconscionable. Do they not realize the average Corvette owner drives these cars about 3,000-4,000 miles per year? Meaning even at 17 (or more) years old, many of these Corvettes have only been driven 51,000-68,000 miles. In the grand scheme of things, on a modern automobile, that is nothing.

My concern is if it breaks, I've read others say the car will sometimes handle "wonky". I don't know much about it honestly since it hasn't happened to me, but others have said it doesn't seem to handle "right" at times? Also, when the EBCM breaks, will the "Check Engine" light on the gauge cluster stay lit for all time or just the "ABS" and/or "Traction "Control" light? If the "Check Engine" light stays lit forever...yeah, that seems absolutely unacceptable.
