I think the following is true regarding the EBCM's from piecing together various threads. Others please correct as needed.
There were two different ABS units (EBCM's) for the years in question. Through early 1998 build dates, the C5's had ABS only - no AH. The pre-AH ABS units also had two different positions on the car - front or rear. Mine is an early '98 (built July '97) and it has the ABS unit at the rear.
Again, I believe from reading comments here, though I am not certain, that it is the AH equipped cars that have the most trouble. The early ABS-only unit I am pretty certain was also used on other GM vehicles - someone reported on here that the same GM part number showed up for a Pontiac.
Neither type is spared by GM.
Personally, I have had no trouble is this area - I did have the column lock recall done twice - there were different versions (aka, attempts to solve the problem) of the fix. The "final", final GM fix, where they basically remove the lock plate seems to be good - it was done years ago, no problems since. But that fix also means the column lock no longer works at all of course.

The GM Recall Service is well known to NOT be a permanent fix for the C5 Column Lock symptoms. As a new Forum member you just have not yet had a chance to read the many thousands of Column Lock problems that are posted here each year. There is even a Stickey that is over 100 pages long with nearly 2200 posts and that is just the Sticky here:
https://www.corvetteforum.com/forums...ky-please.html
There are typically a dozen or more new threads each month on top of the sticky.
Only permanent solution to the C5 Column Lock symptoms is the LMC5. Read about it here:
www.complianceparts.com
Then order and install one BEFORE you get left stranded by the column lock symptoms.........

Jackthelads comments on the column lock mirror my experience. First GM recall was a disaster, second recall has worked to date. I do however carry a LMC5 kit in the glove box.

AH is the Auto Handling, i.e. ESC package - you would have a button on the center console to control it. All I have is a ASC (antilock) button - either it's on, normal, or off, warning light in the dash. If you have ASC only, kook under the rear of the car by the diff for a square box bolted on back there. It attaches to a valve block which has the brake pipes going to/from. If not there it will under the hood toward the front driver's side.
You can go to http://www.c5registry.com/MembersOnl...n/98c5prod.htm, to get your build date from your VIN number.

When the lock would not release one day (after the first recall), I freed it by having the battery charger on for a while, then starting it with the charger set to "boost". I guess that shoved the voltage up just enough that the lock freed quite normally. Another indication of just how voltage sensitive these cars are, I guess.
