Truck: 1995 (OBD1) Chevy K1500 4x4 Automatic w/ Kelsey Hayes 4wal ABS.
Issue: Initiating ABS Power Brake Bleed from Snap-on MT2500.
Finding a unit that would actually "talk" to this OB1 system was a pain to begin with however, finally found another mechanic "ish" who had a unit that would communicate. Problem is, during the actual electronic brake bleeding process, he never put his foot on the brake pedal which made the entire "paid for" effort pointless. Nonetheless, I witnessed the procedure and what unit he was using. The Snap-on MT2500 scanner (old school). I took pictures of his scanner including the cartridges and bought the exact same scanner and cartridges from eBay. Also noting he was using the GM-1 plug, the unit I bought came with many other plugs along with the GM-1 plug. Here's the problem: the MT2500 I have keeps asking for the Multi-1 plug using the Green & Black pins only. And it does indeed communicate however, it's READ ONLY and no option to select the "functional tests" to initiate the bleeding process. Oddly, the mechanic who "didn't do it right" preforming his process, didn't use the Multi-1 plug, he was using the GM-1 plug. I cannot get my MT2500 to do anything "for ABS" without the Multi-1 plug. If I force it, it'll just tell me there's no response from the ABS unit. I'm hoping someone with knowledge of the MT2500 can shed some light on this. I figure, I'm not accessing the right menu or it's something goofy like: even though I bought the same cartridge, (example) his cartridge is Rev. 1.1 and mine is 1.0 so therefore my cart doesn't have the same programming. I hope it's the first figure.
