Anybody familiar with the Snap-On MT2500
diagnostic scanner?

I took one apart that had been dropped into a bucket of antifreeze (saved the guy $3K!),
and I noticed that the ALDL connector on the scanner was a standard DB15 connector. I didn't have the cable to pin out, but what are the chances that this already has the correct resistors and diodes already built in to it? If that's the case, it would be cake to solder up a DB15<>DB25 adapter to plug it into the parallel port.
I can probably get them at cost from my neighbor (he owes me big time now ), so I was wondering if it was worth the effort to check this out...

There's not much to the scanner itself, but the new GM/Chrysler/Ford diagnostic plug in module looks like a 7 layer PC board with propriatary chips wave soldered on both sides...

Do you mean to tell me that nobody has any experience with these scanners and cables?
Sheesh, I guess I will have to go and find out myself...

 

I am the only one on this board that I know of that has/uses the MT2500.

I am sad to say that the questions you ask are above my level of scan tool/cable knowledge. I bought it about 4 months ago complete with all manuals and cartridges (knowing I didn't need them all) just to program a 1227747 TBI ecu in a couple of vehicles. I am presently trying to get/make/get-someone-to-make some software that will create a "new" VE table from an existing configuration so that PROM burning can be made easy.

I hope he/you didn't pay 3 grand for that tool. I paid a little over 2k for the deluxe model off the truck... no deal....

I did't pay anything for it - My neighbor is a snap on dealer and he brought me one that had been dropped in a bucket of anti-freeze.
I had to totally disasssrmble it, wash it with soap and water, rewash it in freon circuit board solvent and dry it out. It works fine now - I tested it on my car for a couple of hours.

That's when I really looked at the cable - it is a standard 15 pin M/F cable with an adapter on the end. There are several types of adapters OBDI, OBDII, etc. They all have a separate 12 VDC power input jack on the side that powers the MT2500. I think I will take an OBDI adapter as payment for fixing the scanner and take it apart to see what makes it work.
The OBDII adapters are pretty neat. They all have a jack for a personality key so they work with all OBDII cars. If you are doing a Chrysler, you plug in the Chrysler key, etc.
