2000 ebcm
Can anyone explain the situation with these parts? Or alternatively if this is asked and answered point me to the most detailed answer within this forum? I understand the part is not made and cannot be repaired or re-manufactured and could render the car undriveable and substantially reduce resale value. I have also been told it is a 1800+ fix if you can find the used part. Any guidance is very much appreciated.

You have several choices to remedy a ECBM problem on a 2000 C5. One would be to purchase a used 99-00 unit and hope that one will last forever, another would be to convert to the 01-04 ECBM (how to in the sticky's above) or just drive with the bad ECBM. On the last one your car will handle like the non-AH C5 corvettes as long as the Traction Control stays working. If you were to autocross or HPDE the car, you would tune off the AH anyway to make the car handle better. My SWPS went out years ago, no active handling, but since i mainly autocross and HPDE the Corvette I don't miss it.

Depending on the failing component they are repairable. There is a thread on this forum on how to do it. I repaired mine. I replaced a small relay in the ECBM and my problem was resolved. The part is about $4.00. If you can use a soldering iron you can replace the relay.

There are places that will fix the p1214 code on the early models. They can fix anything on that top board. The bottom logic board they don't. The P1214 code is not a common error on the pre 2001 models. But it can be repaired.

Yes Ron, I believe you're correct. I think it's the C1255 code of death that causes the ebcm to RIP. OP, before you run out and dump a Grand, or more, to replace the ebcm with a used, unknown quality unit, I'd disconnect the battery, then check all wiring and plugs going to the ebcm, grounds included. Reach out to C5DIAG (Rob), or BC (Bill Curlee) for any info they may have. 2 SMART guys, for sure. Hope this helps.

this is a Cadillac ebcm that I pulled the potting material from. Same stuff on the corvette module. Stuff is like jello. You can probe the logic board underneath and it's not too difficult to pull it out. Have not pulled it from those small wires on the sides, but the board is cleared of it. Some residue there yet, would take a little extra work to clean it off. But as you can see it comes right out.

What I am saying is that potting material is like jello. You can probe the circuits underneath it without removing it. If there is something under there that is bad, it can be peeled away to repair. Those ICs are not going anywhere though. As for replacing the potting material, there are options out there to re-pot the board. So I am saying it is possible to do some repairs of that board. Don't know of anyone doing it, but researching it, it looks to be possible. Depends on what fails on the board.
