My MTG2500 with a 6.2 software cartridge would auto-bleed the ABS on my '03 Trailblazer.
It would NOT auto-bleed the ABS on my '97 K2500.
A Solus Pro with 8.2 software was the same--worked on the '03 TB, did NOT auto-bleed the '97. I'm making an assumption that since the '97 ABS module couldn't be auto bled with the earlier software, other vehicles using that same module also can't be auto-bled. But I haven't tried other vehicles besides mine.
Both of them ('2500 6.2 and Solus Pro 8.2) could read ABS speed sensors, read ABS codes, and other ABS functions--but no auto-bleed on the '97. ABS functions required Personality Key K-9.
A Solus Pro with 14.2 software and Personality Key K-25 (I think) CAN auto-bleed the '97. I have heard--but not confirmed--that the auto-bleed for '97 was added in a major software upgrade for 2010 (10.x software.) The newest-available software for the MT/MTG2500 is 9.x, so I don't think ANY '2500 is going to auto-bleed a '97. I tried PK K25 in the '2500 and the Solus Pro 8.2, but no luck.
The MT/MTG is bi-directional. I could make the gauges swing from one end of the scale to the other on my '03 Trailblazer, turn the instrument panel lights on and off, turn the Damned Daytime Running Lights on and off, I could force AIR to the exhaust manifolds or bypass to the air cleaner on my '88 K1500, force "Limp Home" mode on the '88...The amount of options for bi-directional control are limited by the on-board computer and the software revision you're using on the scan tool.
My MTG2500 wouldn't boot if the temperature was even cool. Had to put it on the floor under the heater duct to get it to fire up. I was looking at upgrading to a newer/better scan tool even before I spilled gasoline on the poor thing, and solvent-welded the cartridge in place. The Solus, Solus Pro, Solus Ultra, Solus Edge, and the current model Solus Legend are DEFINITE UPGRADES from the '2500 series. The 2500s were state-of-the-aftermarket-art...in 1988. They were Danged Good into the early--mid '90s. But with such limited speed and zero or limited graphing capacity, they're totally outclassed for professional use, they're no longer the "hot tip" for even hobby use. OTOH, I still say a dedicated PROFESSIONAL-GRADE scan tool beats hell out of most consumer-grade and software-plus-laptop solutions.
Go Solus or newer (Solus Pro, Solus Ultra...) if you can, and the newest software you can get because there's no updating the software on Solus, Solus Pro, and probably Solus Ultra. Snap-On has discontinued support for those models. NO repairs, NO updates, NO anything. Far as I know, Solus Edge and of course Solus Legend still have support and updated software.
