Piecing Together a Tech 1 Scan Tool Kit

[Jagdpanzer]

Several years ago I picked up this Tech 1 scan tool. All it came with is the 14 pin cable you see. Looking for advice from members here more knowledgeable about Tech 1s concerning the other components I will need to use it on my 94 ZR-1.

This would do only a Tech1 not an (a) with the cable in Phil's snapshots

Phil - If you have the proper MASS STORAGE CARTRIDGE have GC send you the adapter that I borrowed from him to confirm operation for your '94. With the MASS STORAGE and that adapter I believe that you can do ECM/CCM etc for the '94 & '95. I doubt you can do mileage and VIN for CCM but diagnostics. Your current cable would need the 12 pin ALDL connector to use the adapter.

What software do you have? Which cartridge? For your car I believe the MASS STORAGE is required. There's various MSC - GM only and also a MSC that does most other domestics and also imports.

This is the adapter 3000053

The end of your cable has the conventional OBD 1 12 pin to ALDL? If it doesn't then you'll need the 14 - 16 and maybe not the adapter that I mentioned.

Thanks Dave,
All I have is what’s in the photos. No MASS STORAGE UNIT cartridge or other software and no way to plug it into the 16 pin DLC connector.

Sounds like you only have the Tech1(a) and the actual DLC cable, there's a DLC to 16 pin OBD2 cable that would plug in to it or a different cable in it's entirety. I'm sending you a complete Tech1, 1(a) and MT3100 user manual to sort through. The .pdf is (secured) so I'll unlock it before sending. Once it's "unlocked" I may post an image.


The file is sent and when I unlock more I'll send them also. The manual I sent is Vetronix and I don't know that I can convert the Vetronix #'s to those of the GM Tech1(a) when supplied by GM. I'll try.

It looks like your cable has the provision for the 12V either cigar lighter or battery clip adapter that's required. I have the alligator battery clip style I believe still NEW.




See the GETTING STARTED section page 131 of the manual for various configurations. There's Tech1, Tech1(a) and also MT3100 in that manual. I have BODY and CHASSIS manuals for through 2004 also I'm sure.

Does the scanner have a lot more options than the aldldroid Bluetooth scanner?

The images in the manual seem to be "way wrong"! The information correct but images wrong.

JIM (QB93Z) should have this adapter - 02001575. Have him check that for you and maybe a 02001384 if he has that. Those numbers are in the manual but don't seem to transfer to the configuration images.

The adapter that I mentioned in post#2 seems to be the GM equivalent of the 02001575 so with the 02001384 adapter it would work for the Tech1a, I used the adapter with my Tech1 which is a bit different. My DLC cable is dedicated to the early 12 pin ALDL. The 02001575 should ave a toggle on one side of it if it's the same as the 3000053 I mentioned.

BI,

ALDLdroid is a datalogger. The TECH1 has many more functions as far as actually controlling operation of components on the motor, as in shutting off injectors etc. However, the TECH1 doesn't do much as a datalogger other than snapshots IIRC.

Roger that! Thanks

The real value is that much of the diagnostic logic in the GM service manuals is written with the Tech 1 as the sole diagnostic tool for many of the systems. Really makes trouble shooting much easier.

In addition to the mass storage cartidge and proper connector you will also need a power cord. It plugs into the side of the tester and then to the cigarette lighter.

Hello Phil.....
this is my Tech 1 with all of the connectors that you would need for your 94......

here is the Tech 1 with the OBD 1 connector and the power cord to the cig lighter.....

this is my Mass Storage Cartridge.....

which you can see has been updated throughout the years.....

this is the interface that you need to use in our 94 OBD II connector....and you also need that adapter on the left of the interface, which I did not take a close up pic....you will need all 3 separate pieces shown here to connect to the OBD II.......

close up of the interface part#.....and the right side adapter part#.....
