Default Really important tech question EBTCM 1995

I have other threads going on this but I need a VERY specific answer for this. Please no guessing. I need a new abs/asr ebtcm module for my 1995. The factory SERVICE MANUAL is wrong, it shows and trouble shoots 94 and earlier - completely different design. The 1996 book shows correct module for 1996. I thought the 95 and 96 module was the same but unsure due to factory service module error. Does (and more than one answer would be appreciated) have a TRUE 1995 stock car that can verify the manufacture date and the actual part number on the EBTCM on your unit. I wonder if there is a late break point where they started using 96 units on 95. There is one 9/32 bolt holding the rear trim compartment down then raise up the panel and you can see the part number. Some vendors...dealers some not show specific 95 and 96 ebtcm's . But all the wrong info has me scared and these things aren't cheap. Please help this old corvetteforum veteran. I am usually pretty good in these types of problems! direct email is corvette95@charter.net

Does this give you what you need?
My hard top is installed so there's no real way for me to get a good look at it but I can get the old Iphone in there easily enough

You need to start with sharing the information off of what you believe to be your original, the VIN of your car and a production date from the Certification Label. What is the part information from yours?

BTW - there's no "guessing" on my part YOU need to share what information YOU have. Comparisons can then be made and "validated"!!

I don't have a '95 FSM so I won't dispute your claim to "wrong" but an LT1 module is different from the LT5 module in '95. You replaced harnesses and asked for specific part #'s earlier but you didn't mention where the information came from. When you replace harnesses you start with the tag information from the original seldom from any other documents.

Thanks, I am trying to read your number, according to a couple of sources the last digits for a true 95 is 1973., Your picture does help thanks! Anyone else?

I know LT5 and LT1 are totally different. I am getting a phaton code for continuity but EVERYTHINGS checks out. Car is at Jim Van Dorns in Bowling Green and he is having same tracking down problems as I am . Everything checks good. I replaced three ebtcm's all giving same code as OE. He thinks I have a 96 module in it but dont think its the problem. He wonders about the wrong info in the manual as I am. I am in Alabama and the car is in Bowling green so I cant give you the old numbers just right now but will try to get.

I was outside taking better pics and then uploading when you made your last posts my vert is a 1995 with a build data of 6/95

Looks like bosch manufactured my ebtcm in 94.

I posted all of those pics since between them all you can ascertain all of the numbers. Which number are you looking for? I've had this 1995 since 2004 and it was relatively low mileage and unmolested prior to my ownership.

I personally believe 95 and 96 share the same unit. 94 and earlier were two part completely different units. Believe me I want to give you all the info I can, I just don't want to confuse this particular question.

I think where your says 1922 , per Jim Van Dorn some people are telling him its should be 1973. I am going to try to call in a favor ( and BTW thanks for all the pictures) at my GM dealer and see if they will call their techline. I think 95 and 96 are the same too. Thanks SO MUCH! I will post all the info I get. I get a continuity code 23 RF wheel sensor... ohmed it all perfect...three NEW wheel bearings, three new (used ABS Pumps) and a complete NOS (yes new) wiring harness...still get instant code 23.

The 1922 is actually a 0922.

This post has the correct image for a '95 EBCM for an LT1. It has the correct service number on it for an "off the shelf" correct unit. The valve which I believe you guys are discussing and have an image of displayed is the BPMV.

Here's an image from that post:

Thanks , that helps but this is only the module part of the pump, do you have picts of the other half with parts numbers for the pump itself?

I believe that the 10273704 that "aboatguy" took a snapshot of would have been the OE/production BPMV for a '95 MY car. Your original post and all of your comments reference "module" and they're two distinctly different parts! You complicate it by trying to reference numbers that aren't OE or don't even resemble OE. The clue to the BPMV on the snapshots "aboatguy" supplied are the notations on it for MC1 and MC2. That's the BPMV.

The module in "aboatguy" snapshot is the component directly above the information on the BPMV and you can see where he two pieces are connected by fasteners and I believe that's one of the fasteners in the image top left. The separation of the two different components is quite evident in his snapshots.

If that's the assembly you need the numbers off of sorry brother no way to see that while its installed in my car. (If there is a sticker on mine its on the driver-side and too close to the side of the well to read. )

Might be late but I found out he hard way, both the factory service manual iw srong along with gm parts catalog. The 95 ebtcm is a ONE AND ONLY YEAR unit although 96 fits perfctly...wont work correctly. Verify know good 1995 only part number when you replacement. Dont go through what I did!
