Please.. Final ECBM 1997-2000
Hey All,
As a new pre 2000 C5 owner and not heading the warning of the dreaded ECBM problem. My "new" C5 has the 1243 Code showing. I've read lots and lots of questions and answers in CF in reference to this problem. Can the corvette gurus of this amazing forum, chime in with final answers for the resolution to the ECBM?
If it is definite that the ECBM is bad can it be fixed? If the answer is No, then lets say it and put it to bed.. IF someone comes up with a fix. Please Post here..
Maybe the question and answer should be a sticky??

well you could try this to see if you can free up the pump. at least it's not the ebcm module.

I've gotten in the habit of putting the rear of my car up on jack stands and spinning the rear wheels to make my ABS go nuts. I do it 2-3 times a summer just to make sure I don't have issues.
Would flushing all of the brake fluid help? Like finding someone with a Tech 2 and flushing the entire system, replacing it with new fluid?

For the specific error code the OP posted it may be possible to apply 12v to the pump motor directly to free it up. Then follow it up with a complete brake fluid flush and cycle the pump using a Tech2, since in the last 17yrs the brake fluid probably has not been changed.
Applying 12v to the pump directly will cause it to run and move the fluid around. Like some starters it may take a wack to the housing while applying power to get it to run. This is what the link posted above recommends to do.
Once working it would be a good idea to do some panic stops at least once per month to keep the system working.

A friend is an engineer (chemical engineer of some kind--in the pharmaceutical industry). I asked him if he might be able to look into this issue, see if there is a way to overcome the epoxy (maybe use some kind of liquid or other material to "melt away" the epoxy). He basically informed me (in engineer language--so I have no idea what he was talking about when he got granular) that the bonds of an epoxy are so strong they're almost "unbreakable". He told me to think of the epoxy as similar to a tire...you can't just melt an old tire to nothing. Burning it is pretty much the only way to "destroy" it. That's what epoxy is like.
People keep replacing these units with other used EBCMs, but eventually the supply of used ones that work will probably dry up...meaning all C5s will be without ABS, active handling, and traction control with a bunch of lights on the gauge cluster.
I think it may be inevitable.

There was a thread a few months where someone had figured out a way to convert the newer EBCM to work in the older cars. I don't have the link or suggestions for google terms, but I feel your pain.

1.) It took something like 70+ hours if I recall from the post. Obviously with the instructions the person posted, an experienced shop could do it in say...half the time. Problem is, that's still 35 hours. At $100/hour for labor, that's a $3,500 upgrade from a shop. Unless you can do it yourself...but still seems like a giant project.
2.) As some on here have posted, now 2001-2004 C5 EBCMs are on national backorder. They have been for months apparently. Who knows if that is temporary or permanent? Imagine if you go to the trouble of upgrading then '01-'04 units aren't available.
Yes, '01-'04 units can sometimes be repaired...but sometimes, they can't.
Obviously, 1999-2000 owners (like myself) are hit disproportionately hard. I just think at this point...all C5 owners have to come to the realization that GM isn't coming to the rescue and eventually, over time, all of us may have broken EBCMs. As time progresses and these cars rack up more hours and miles, more and more owners are experiencing broken EBCMs. Seems like eventually they will all fail and all C5 owners will be SOL.
