TOM -


Yours is a Tech1 and Phil has a Tech1(a) - they require very different cords, adapters etc.

The MSC will work with either. For your Tech1 to do '94 & '95 cars I believe all you need is the 02001575 I mentioned which is the same as the 3000053. You don't seem to have that or you didn't include a snapshot.

NOTE on the one adapter combination (snapshot #4) the one component is actually molded (DO NOT USE WITH TECH1A)

Perhaps Jim or GC will post a snapshot of the 02001575/3000053 which you would need for '94 & '95. With a Tech1 I've used that adapter to do Buick '95 which share the same 1.5 or BETA OBD.

Jim can maybe post a snapshot of the other I mentioned I believe Phil needs for the Tech1(a). That's the 02001384 which I believe in an earlier thread years ago he mentioned having.

The manual I have from Vetronix/Bosch has some very good images of configurations but they've erred in adapter ID in a couple. Once ID'd I might edit the .pdf with part#'s. I took down a couple images I had posted because the mention PIN-E in the images and it's NOT PIN-E.

I've always thought YOUR 3 piece combination(snapshot #4) is meant to be used for true OBD2 in '96 or newer using the Tech1. Have you actually used it on your '94? I have the same package for my Tech1. Mine ain't as pretty as yours though - well used or abused maybe fits.

Here's a 6 year old thread where Jim mentions having the adapters that I mentioned:

Dave.....

I was under the impression that it would have Tech 1a imprinted on the front of the device as I have seen many times.....
I didn't know that series (a) on the back of the device refers to it as being a Tech 1a.....if that is the case, I imagine it was for the very early Tech 1a scanners..
Again, all of the Tech 1a's I have seen were always labeled on the front..
My interface and adapters work fine on mine for the 94. We also used the scanner on Charlie's 92 at Carlisle without the adapter to make an adjustment...😁

And yes mine is in good shape.....got lucky on the purchase.....

If Jim has the 02001575 still you might try just using that single adapter and check your '94. The combination that you and I have is very bulky, mine when connected is maybe 8' long. Were you able to access the CCM using yours to verify VIN and ODOMETER? If you were able to access it then it's likely that your MSC and Tech1 could program VIN and ODOMETER into a rebuilt CCM. You can't ALTER but likely enter them.

Phil's snapshot #2 is confirmation of the Tech1(a) - Tech1 has no additional ports on the side, only Tech1(a).

Thanks guys, excellent advice.
Did some searching around and apparently PN 3000003 mass storage cartridges are hard to come by. Nothing on eBay. Are there any other places I should be checking?

There is one Mass Storage cartridge on eBay. It’s part of a grouping.
Auction #232512025290
Good luck

The ....003 is a GM "only" configuration as a rule BUT not necessarily. It would be dependent upon who did the updates. I have a MSC VETRONIX 02002663 that has GM, CMC, FoMoCo and most imports OBD1 & 2. I also have a VETRONIX 02001718 which is "power-train" GM '81 - '94, FoMoCo '81 - '93 and CMC '83 - '93. I've never tried the 02001718 - it might be interesting to try it. I have the GM ...003 also, not sure of the SW version.

The eBay offering is interesting but the MSC would depend upon the SW/version "update" that's on it.

I have a power cable, the MSC and others so if Jim had the 2 adapters I think there's enough to actually confirm the "functionality" of your Tech1(a) before you bought a thing. You're of course welcome to them to check.

I just checked the one I have and the manual refers to a Tech 1a. It has an Ethernet port on the side. I only have the carts for GM 81-92 ECM/Brakes/Body but no MSC. Also, no 94-95 ALDL adapter.

I did not try that feature as of yet......I want to learn more about it before I do something else.....like erase something that I shouldn't have!!! I have just been using the function that FO allows you to do and that is just reading data....lol I'll get brave somewhere down the road and look into the other capabilities that this scanner has......

[WVZR-1]

It appears that on the MEMBERS ACCESS there's Tech1 & 1a user guides for Chassis and Body (2 files) that have images and configurations in "GETTING STARTED" section. I don't know if there's a POWER TRAIN user guide there or not.

A question - what is the ideal scanner, cartridges and connector combo to service 94 model?
I've been thinking about looking for a Tech 1 but too daunting not knowing what I need.
