I have a 1995 GMC Jimmy V6 4WD
My ABS Light is on and none of the local auto parts stores have a diagnostic tool to read the codes.
Does anyone have any idea how I can go about extracting the ABS Codes for my vehicle?

a 1995 Might be an OBD1 system - so long ago I cannot remember - 5iimutes and a paperclip to check it out...
otherwise it will need appropriate tech1 as mentioned
STEP 1
Need to confirm this is OBD1 and NOT the dreaded OBD 1.5...
try jumping th A to B terminals of the ALDL - any codes will flash. if yes then record then and try step 2
STEP 2 jump the A to H terminal of the ALDL - takes a moment to begin sequence -then count the ABS light flashes same as ck eng light codes ...and post info...

Some had PCMs and some had VCMs. If it has a VCM, a scan tool is the only way.
If it happens to have a PCM, you can get flash codes.
Ground terminal "H" to terminal "A" of the DLC, and counting the Anti-Lock lamp flashes. The terminals must be jumped for a few seconds before the diagnostic trouble codes will begin to flash. The "ANTILOCK" lamp displays DTCs similar to the malfunction indicator lamp for the fuel and emissions system.

I am having a hard time uploading a pic of the module that is in my Jimmy. If is is possible I can e-mail it to someone and ask that they post it to the thread so that everyone can see what it is I am working with.

Most of us use Photobucket to host images. It works well with the site.
We don't give out e-mail addresses.

That means you're back to square one and will have to find the right equipment.

No, he's going to have an OBD2 connector.

OK - and the picture you took time to send? - the suggestion to use a paper clip-
instead playing with downloads etc was easier than - not the ALDL in vehicle?

I have no idea what you are asking me but if he has a VCM, then that means he has an OBD2 connector and no flash codes.
