Re: A question about the Tech 1 Scanner.
 

John actually you do. Remember the Tech-1 is from the Atari generation. The brake systems module is a mass storage cartridge. The tech-1 without these cartridges wont know what to to as the cartridges contain the programs. Thats why there are so many cartridges from EEPROM to Body systems, to Chasis systems ETC.

Re: A question about the Tech 1 Scanner.
 

John do you have a source for these new or used?

Re: A question about the Tech 1 Scanner.
 

I do have a used 94 Lateral Accelerator that I got from someone on this net. It came out of an 8,000 mile car. The pendulum is free, so I think it works. My 90 was different, so I could not use this one. Let me know your p/n and I will check it.
I paid $29 for it.

Re: A question about the Tech 1 Scanner.
 

Im interested if Jeff doesnt want it but im not sure if a 91 one uses the same as a 94. I will reference a few numbers. What part number is it?

Re: A question about the Tech 1 Scanner.
 

There are two numbers on the part: 10143543 and 09401032.

Re: A question about the Tech 1 Scanner.
 

Wont work in a 91 and the mountings a little different :icon_scra

Re: A question about the Tech 1 Scanner.
 

One of the cartridges I have is part # TKO3030C and it labled GM 88-92 BRAKE [VERSION 2.0]

Re: A question about the Tech 1 Scanner.
 

fwiw....that sounds like the cartridge you need to plug in to do ABS. I know on my snap on scanner I have to have the "GM Master Trouble Shooting" cartridge plugged in and the "ABS" cartridge plugged in to do any ABS work.

Re: A question about the Tech 1 Scanner.
 

The TK03030B is specifically identified as "88-93 ABS". I have a TK03030 marked "88-91 Brake". I don't know if TK03030C "88-93 Brake" works for ABS. I think they are specifically marked "ABS" I think you also need a specific ALDL adaptor for doing ABS diagnostics. I am not 100% on any of this, it's just what I understand from reading the Tech 1A manual.

Re: A question about the Tech 1 Scanner.
 

I got the ABS adapter and still got nothing,I give up on this bull$hit.Ill just keep my eye out for somebody else thats having the same problem and learn from that.What have I tried?Paper clip,cheap auto parts scanner,4 high end scanners and finely the Tech 1 scanner.I know if I keep plugging away Ill find the problem,I just thought I might know what the problem is by now.This all started after I replaced the brake pads,I remember I had to force the pads back into the bores of the calipers so maybe I did something.I might check the switch at the M/C.Thanks a to all for the suggestion.
