BlackC5 Z06

I've been looking for a C5 for awhile and remembered awhile back reading if the EBCM unit goes out on 97-xx year they weren't fixable and they quit making the part. So you had to either buy a used one which is a crapshoot and a lot of $$$ or just not have traction control.

What are the years? 97-00? Thanks! And do these go bad with more miles or is it just an age thing? Thanks.

Yep, 97-2000. It's a crap shoot, some never go bad, some go bad with either age or mileage. Really, when it wants to go, it will.

Thanks guys thats what I thought. Was hoping it was fixed in 2000 but I guess not. I've found a nice 2000 but am a little worried about it going out. Does anyone know the failure rate of the ebcms?

Was there not a post 2000 EBCM swap thread? It was done.
Vettenuts posted in it that thread they were willing to tackle the swap . Not sure if they ever carried that out.

Greetings,


I have a 98 with 75k on the clock. I have no issues with my EBCM. However I did come across this site.

Never seen this website before...if they somehow have found a fix for the ebcm without active handling than thatll be something great and new.

Look at the fine print. You need a shop to order the part. Not for personal sales. Shop needs to diagnosed with the a Tech scanner. Just saying

Agreed

There is a sticky right in this forum for updating to the later model.

Not super easy, but quite doable

Since my 99 EBCM went out and I replaced it with a used one, I took apart my old one. They are repairable to a point. If the logic board below all the goo (feels like jello) is bad- it's done. If the top board (power board) is bad then you can repair it or swap top boards from another good EBCM from another car (not necessarily a Corvette, that same board is in other Chevys as well, and cheap). That logic board is protected from the elements from that goo. The top board is not. If the seal around the EBCM is bad, water or moisture will seep in and corrode the components on the top board. That will cause power problems and then you get the C1255 code. Another problem with these units is cold solder joints over time. That too will cause power issues and a C1255 code. Mine had a burn mark on one of the ceramic capacitors making problems on the power board. So they are repairable IF it is something to do with the top power board, otherwise its dead.

I'm pretty sure the link above to that repair site is doing just that. Repairing the top board components or fixing the cold solder joints. Not all can be repaired, but some can. Since a C1255 code is an internal problem sometimes power problem based, that top power board can be the problem.

What a bummer. Only $280 for the old module and only $60 for the newer module

If you need a ECBM repaired I would reach out to that company anyway and see if they can help you. Or go and make yourself a company and send the information they are asking for it. I highly doubt they will check to see if you are a legit shop.

With all the ECBM failures, I would think more people would be praising this company if it were able to repair ECBMs.

Thats what im saying...even if I had to take it to my trusted corvette shop and they do the transaction, this would be great news.

I have never seen anyone successfully report having the early model EBTCM fixed by a repair shop.

Lots of people have had these shops claiming they can do it just steal their money though....

At the end of the day, there isn't much that could be repaired in either module, new or old. About the only thing being fixed in the new module is cold solder joints or replacing the relay.
