Thanks for posting the letter about the EBCM repair, Bill. You've restored hope for now. And I think the door control goblin already reared its ugly head. Two down, two to go.

CODE READER???? You dont need to purchase a stinken code reader!!! Your C5 has a built in code reader!!!
Here is all you need to do!!!
This is the absolute best C5 Code web site!!!

Select: Technical Data Base, then 1981-2004 Corvette ECM Computer Codes, Then your year C5, then read the directions. At the bottom of the directions page you will see “READ MORE”. The codes are on that next page.
The sound effects are cool too!!

Bill... thanks for the "friend" notation on my e-mail.
I have also found 2 other repair shops for EBCM and ABS systems, still awaiting a reply.
They don't offer a lifetime warranty, but they are also much cheaper. around $150-$200.
I will post further details if they do indeed repair the corvette modules.

[QUOTE=c5_pewter_vette
I had a used EBCM coming from Gene at Gene's Kar Shop. I thought I would remove the EBCM and get that part of the repair out of the way. Once it was removed, I burnished the contacts on the EBCM lightly with a file. I measured voltage and resistance on the harness connector and everything looked good. I also burnished the harness connector pins.
I then put the EBCM back on the BPMV, plugged the connectors back on and fired it up. No problems and no codes. Everything works fine. Prior to me removing the EBCM, I got C1214 almost continuously and it would not clear.
Before buying a new EBCM, take a small file, emery board, etc... and gently scrape (burnish) the mating surfaces of the connector pins. Don't press too hard or you might deform the contacts or rub off the plating.
I have a gut feeling that these intermittent C1214-only problems are primarily contact related. Changing the module changes the mating of the connector (new pins) and solves the problem. At least it's a theory. It would be nice if you guys with intermittent C1214 codes could duplicate what I did and get the same results.

P.S. Nice pictures Bill. I gave up opening mine as it looked like the insides were potted.[/QUOTE]
I'm having the same problem on my '02 (18,450 miles). I'd like to try the connector cleaning approach. How do you disconnect this connector? If I release the latching mechanism, the connector disengages but does not come off. How do I get it off?

I had the same problem last night- where the white safety lock attaches, that black thing is a release clip too. You have to press it down I believe, while moving the big latch. then it just pops off.

I found this EBCM repair service on Ebay for $49. It is 1/3 of ABSFixer. Has anyone used his service?

I'm an electrical engineer. I may try to fix my defective EBCM. I believe GM uses Omron relays quite frequently in the vette - I might be able find a replacement and switch it out. I'll know more when I take off my EBCM and look inside. It bothers me that we're forced to scrounge around for used modules or buy new 
when replacing a cheap little relay with bad contacts would do the trick. I wish I had a schematic of the EBCM.

I had the C1214 fault on and off for a couple of years. Finally had enough and decided to get it fixed.
Pulled the EBCM from my Z06 a few weeks ago and sent it off to ABSFixer. One day turnaround , reinstalled and end of story
Very reasonable cost and super outstanding customer service. Kudos to Brandon at ABS fixer. He was responsive to questions and emailed from receipt to shipment back.
Super easy DIY job removing and reinstalling . Someone on the forum posted a link with great instructions. Only little issue I had was getting the two middle screws started on the reinstall. I did all work from the top and only had to move the air bridge out of the way.
Like my old FIAT ( Fix it Again Tony), these C5's keep you on your toes with odd repairs.

I know this is an old thread but I have been having an intermittent problem with the Service ABS Traction Control light and it throws code C1214. I tried cleaning three ground points in the engine compartment. I noticed not much corrosion but a lot of sand in the black boxes where the wires connect to the ground eye. It seems to be coming in from the wire side of the boxes. Cleaning the grounds did nothing to correct the problem with the EBCM.
I pulled the two plugs off the EBCM and dumped sand out of those also. I also cleaned both plug ends and the EBCM receptacle with a wire tooth brush. I plugged everything in and the warning lights are out. I cleared the code and started the car, not throwing the code anymore. Not sure how long this will last but there is definitely a connection between the two.
