Help me piece together my Tech 1a please ... pics of what I currently have inside ---

[alwayscode390]

I bought a Tech 1a and have been getting cartridges as I run across them. For some reason I cant find a power plug, or the correct plug from the Tech 1a to the ALDL (DLC cord?).

What are the part numbers for those two items? Do you know where I can find them? Anyone have them for sale?

I am about to sell the setup if its just going to sit around.

Here is what I have so far:

* Carry Case
* Instruction Manual ( which seems like hieroglyphics until I get a chance to actually test the unit )
* Tech 1a handheld unit
* Techline Power / DLC cord # TA00011A , which I think is wrong because it doesn't seem to connect to the handheld unit. Has a lighter power cord, 12 flat pin male connector, and 15 pin female connector. Has a Chevy dealer tag on it from 1993.
* 4 Master Cartridges:
- GM 81-92 ECM # TK02050
- GM 88-92 Body Systems # TK03040
- Chevrolet 90-92 EE Prom Data Version 2.0 # TK06032A
- GM 88-92 Brake # TK03030

* 3 Adapters
- 14 PIN DLC Self Test Adapter # 02001607
- GM 12/14 Pin ALDL Adapter # TA01140
- Phone style plug-in (short)

Let me know what else I should pick up too, thanks! ---

Vetronix (now Bosch) sold me the data/power cable pair when I sent mine in for repair. I got the impression they didn't have too many new ones left. It was more than $100, but it was good to get because it is the part that gets the most use.

I would guess they have a stash of good used ones somewhere if you ask.

[alwayscode390]

Awesome tip , I didn't know they are now Bosch.

I will try to find an email I can contact them at to ask.

I am sure once I start fiddling with the handheld it wont seem as confusing as it does to me right now. It just seems so archaic , lol

THANKS! ---

[mike100]

Examining your original post, a little more clearly, it looks like you are only missing the portion that adapts it to the main unit. I'm away from mine right now so I can't give a more detailed instruction. The cable section you do have is the hard-to-get-new part though so take good care of it.

[alwayscode390]

So I am missing the adapter that goes from the cable to the handheld , but I have the right cable?! That would be awesome!

My cable is in HORRIBLE shape though, so I still may try to find a better condition one.

This cable has the lighter power cord into the "power in" portion of the 12 pin side ... and nothing on the "power out" portion ... so I will need something to link the POWER OUT to the side of the handheld or will it power up through the adapter once connected?

I emailed BOSCH lastnight , no response yet ---

Here is a pic of my cord , it looks like the "power in" portion was broken off ... and the lighter power cord was "hardwired" into the 12 pin male side. The tag says "good spare" on it , so I am hoping it works.

The way its set up , do I need a cord from the "power out" to the side of the handheld or will the power be sent through the top of the handheld via the adapter when I get it?

My car just threw the INFL REST code , do I have the right cartridge to delete that code after getting the corrosion off of the frame sensor?

Thanks a TON!!! :) ---

[alwayscode390]

That 12 flat pin male side where the power is hardwired, that goes into the ALDL under the dash , right?

So , I will need a male 15 pin ( cord side ) to male 26 pin ( handheld unit side ) adapter?

Do you know what part number that is?

I feel so close to getting this to work !!!

THANKS! ---

[mike100]

The 12v lighter plug sockets into the hole shown and goes thru the missing cable to the main unit. I guess you could splice in 12v one way or the other if the socket is messed up.

As far as cartridges? maybe the 88-92 body systems covers the airbag? I don't recall off the top of my head if it is included with that group. The one thing to lookout for is the 3000003 'Mass Storage Unit'. That is just a much bigger array of memory with all cartridges in one unit. I think these were offered a little later on as memory technology progressed. There's one on ebay for $150 right now. It does come in handy to cover a wider range of cars and you can leave the collection of cartridges at home, for the most part.

[mike100]

Don't feel bad...I had to spend $690 to get mine ship-shape. I have fixed 4 cars with it though- it definitely does neat tricks.

[alwayscode390]

I was told the EEProm Data was the Mass Storage unit?

I am getting confused as hell ... my lighter cord , is hardwired into the "power in" plug ... so you are saying I am missing the "power out" cord that goes from that plug into the handheld unit?

I posted a pic above of the rigged setup I have. If you need more pics let me know and I will take them for you.

I should probably just sell this thing ... how much do you think everything I have should go for?

The actual hand held is in GREAT shape, no flaws at all ---

How many pins are on the scanner 15 or 25 on the end opposite the cartridge, not the side!

I have a Tech1 but NO Tech1a to look at. I have the same cable that you have as well as another and both are correct for my Tech1. If your Tech1a has a 25 pin connector (on the end) I believe you need a correct cable. There's several with Tech1a's and I would think they could confirm from the cable which one you need. I've never been aware of a 15/25 adapter to take one to the other. I have seen 15/25 but I didn't think to be used for either the MasterTech or the Tech1/1a

My TA00011A cable has a 15 pin on it to the scanner. The other cable I have on my other Tech1 is a TA01139B, it does NOT have the "power out" option.

[alwayscode390]

Here is the top of the handheld.

I think its 26 female pins.

Then there is a phone plug with a single female plug below it (power?) on the left side , and a phone plug on the right side.

It takes a master cartridge or an auxillary cartridge.

Here is a pic of the top, above the screen:

This unit originally came with a MARINE cord and cartridge ... I wonder if it was custom swapped out with a different piece up top to connect the cord to?

Thanks for pointing out I have a Tech 1 power/data cord ... I didn't even realize it was different than a tech 1a , that helps me a lot ! ---

[mike100]

If you have the RJ45 jack on the side, you may have an early Tech1A- just it was still labelled as a tech1 until they marketed it as an upgrade with more testing capability. That is how mine was. After factory refurb, I got the tech1a label and a new keypad label as part of the refurb.

The jack plug is for the voltage probe feature to inject certain test voltages into various circuits according to factory procedures that may call for it.

[WVZR-1]

Someone just needs to remove the cable from their Tech1a and confirm the "pin-out" and the part # that is on the cable, either molded in or on a label. All of my Tech1 cables are 15 and to be perfectly honest I've never removed the cable on a 1a that I've used.

GC - I believe has a 1a and Mike100 should be able to confirm what's on his. He mentions his is a 1a.

[alwayscode390]

^^^ You guys heard the man ... that's what I am looking for :) ---

[WVZR-1]

I believe you need likely these 2 part #'s mentioned in this post - the thread goes on to discuss ABS that you're presently not interested in so I just used the single post.

http://zr1.net/forum/showpost.php?p=181330&postcount=1


Where is the "marine cord" that you mentioned? I believe that's what you're needing likely.

[mike100]

GC - I believe has a 1a and Mike100 should be able to confirm what's on his. He mentions his is a 1a.

I'm 380 miles away from mine, but GC will be home soon I think- hopefully he can have a look at his.

[Marq21]

My Tech 1a has the following cable/connectors:


14 Pin DLC Cable - TA01150 - connects from the handheld and is mated to the next connector:
GM 12/14 pin ALDL Adapter - TA01140 - this connects to the ALDL unless I want to read ABS codes, then use:
Bosch ABS Adapter - TA00022.
And you must use the GM Chassis Cartridge (or the Mass Storage Cartridge that has all the software on it) to read ABS or FX3 (Select Ride) Codes.

Hope this helps. Troy

[alwayscode390]

BINGO , thanks a ton Troy ... I think that was exactly what I was hoping someone would post up !!! :D ---

[alwayscode390]

OK, I already had the TA01140 adapter.

I just found and purchased the DC Lighter Plug Power Cord, and Bosch ABS Adapter TA00022 from Ebay ( to have for later ) ... now I need to find the DLC cord and I think I will be in business.

I think the Bosch number for the cable is #02001637 for the 14/26 pin cable. I am going to call and see if I can get one from them directly, new.

THANKS!!! I am feeling a little better already :) ---

[alwayscode390]

I think I found a used Bosch Cable.

Bosch contacted me back this morning, and said I need a business account with them to purchase anything directly through them ... and I need to find a local business to see if they have it or can even get it LOL.

Good thing I found a used one, that seems like quite the hassle. ---

Its also a printer port for a very early thermal printer. Also the early 1A are labled on the back side before they labeled the front side later as Mike correctly states.

I'd rather hunt down a vacuum leak, than find a bad circuit... I THINK.

Although electrons are a little harder to see than AIR :p

But Schrade, Electrons should be attracted to you because of your positive personality. :)

Ok top is indeed 26 pins here are the pics of the parts you will need to get that tech1A to work. Noticed how the power supply plugs into the adapter in pic three? That's the one you want. The Tech 1 uses a separate power that the tech1A combines

Perfect, so you plug the power into the DLC cord ... can you still plug it into the side of the unit if you want , too?

Thanks for that ! ---


EDIT: The cord I posted on the first page combined the power into the cord also ... is that a tech 1 cord? Its a 15pin to 12 pin cord. I need to identify it to sell it :) ---

I cannot remember I believe the unit can use either. However I have an early tech 1 A and it also has a power input on the side as well
