I was thinking in the direction of using the 01+ computer as a stand alone to operate the newer abs????? As I understand, the 01+ electronics are not backwards compatible to the pre 01?
Are the connectors still available?
Would seem pretty straightforward then to just run the abs?
I may try this. Of course all testing would be in an off road safe situation.

I've got the 3-volume GM service manual for the '99 and access to a Tech II (and HP Tuners for my VIN if need be). As far as schematics go - I should be able to extract all the relevant '99 vehicle-side info.
I've been thinking though, if this were to work you'd need to do ABS/TC/AH diagnostics by telling the Tech II that it's an 01+ vehicle (I'm guessing) - not sure how that would work out when it polls the other ECUs.

Good point. The voltage ranges and response characteristics would need to be compatible. Anyone have access to pull GM part numbers for all the inputs to the EBTCM (99-00 vs 01-04)?

I just pulled a Delphi unit off my friends 99 FRC, I built a cover to protect the flexible soleniod voltage circuit while Corvette salvage try to repair it. They say they have a test car specifically for testing this and maybe able to repair it, well see.
My question is the solenoids in the two center rows, the bottom two both sides are 5 ohms. The solenoids on the outer rows are 9.5 ohms. Anyone have these measuements off there car?
Thanks,
DJ

We have used ATE for the repair of our EBCM with JL-4 code. I have invested $689.00 plus $130.00 in shipping and the unit is still not fixed. Now they are asking an additional $1141.00 for a replacement unit, which is going to be a used repaired unit. I am not sure what to do yet, just letting you know of my dealings with this company. If you will, let me know how yours turns out.

Some time in the mid model year, they moved to the front.
In Model year 2001, the entire EBTCM/BPMV changed to this type.

I have 5 or 6 of the 97-00 versions and have had no luck finding anyone who can repair them. I sent one out to the company on Ebay that is in TN and it was a joke.

I called BBA Remanufacturing on May 10, 2011. Mike at BBA Remanufacturing told me that they could repair my 2000 Electronic Brake Control Module w/Active Handling in 1-2 days for $225 plus shipping, with lifetime guarantee.
Since I've seen prices to rebuild these modules in the $500 to $900 range, I inquired what service I was paying for in the $225 price. Mike's response was, "what are you worrying about?...it has a lifetime guarantee." My response was, "Uhhh...because I should have a right to know what you are doing in case the scope of the "repair" is not to my satisfaction...because the EBCM is a vital safety component and its proper function can determine the life or death of my passenger." I thought to myself that I won't be making a claim on BBA's lifetime warranty if I'm dead. Mike replied, "Asking us to divulge what we do to repair your module is like calling KFC and asking for the secret recipe." I laughed and argued fruitlessly. I was shocked at Mike's shady response. A couple weeks later, after having my EBCM removed at the Corvette Shop in San Diego, I reluctantly shipped my EBCM to BBA against my better judgement. I waited ten calendar days and received no call. I called them on Tuesday, May 31. They informed me that they "couldn't fix my unit." I asked if my unit was OK or they were simply unable to identify the cause. They said that they saw the error codes, but couldn't determine which component was causing the communication failure.
I arranged to pay for return shipment. Today I'm still waiting to receive my part back.
I suggest you not waste your time with BBA Remanufacturing in Taunton, MA.
Next, I'm going to try "ATE" (Auto & Truck Electronics; 866 983 6688www.autoecu.com), also known as "ASI" on Ebay. THey claim that they charge $495 and that includes replacing all components on the green circuit board. If I achieve success, I'll repost.

Well here we go. I have been checking on all the same companies and I have been on the phone with GM for two weeks. They didn't know what they were speaking of...they even called me to ask if I picked my car up from Tony's Corvette Shop yet and was I happy with the results!!! They called this morning and said there will be no recall, no production and no help whatsoever for all the Corvette owner's of America. I have a question, why hasn't there been a class action suite filed against GM for this? To have one of their best cars come out with defective EBCM's is just absurd! I have been reading about this problem since 2000 when I purchased mine. I need one now and the only way I have heard of a fix is to replace it with a used one. Then of course it will be just a matter of time before it breaks again! GM refuses to design a part that works and they have absolutely nothing to say other than "I'm so sorry Sir". This makes me so mad...I will never purchase another GM product. There are plenty of very well made cars out there with companies that stand behind their product. IF this is the best they can do with one of their supposedly best automobiles, then they have real problems! Good luck to everyone and I look forward to someone finding a breakthrough so I can fix mine after all, it's only been over ten years for me now. I can't repair it, HELP!!!!

Technology with computers, sensors and great enigineering will make ALL future cars having the same problem.
IF our wonderful govt. or Lawyers FORCE manufacturers to support past products for X years you would see $5,000 modules and such.

ASI/ATE didn't work. Stay away from them.
ASI/ATE didn't work. Stay away from them. I filed two complaints with American Express that were both denied. I'm getting ready to return the module to ASI so they can go another round. I'm sure it won't work. Between ASI and the labor to install and remove the ASI-repaired module, Im out $650.
