I used to check wheel speed sensors on my '92 and '93 Lumina with an MTG2500.I'm not aware of a single bidirectional OBD1 specific scan tools, nor the ability to communicate with an OBD1 ABS module outside of a GM dealership using a Tech 2.
Can't communicate, or can't auto-bleed? Big difference.Now, I do have the GM1 adaptor for my SnapOn Solus Ultra and I still can't communicate with the ABS on my '95 C2500.
Pretty sure the service manual says the Tech 1 (or Tech 2) is needed to bleed the aluminum-housing RWAL units.I only have pickups from the early generation with RWAL, perhaps you know something I dont about the 92-94 SUV 4 wheel ABS needing a scanner to bleed them?

Is this 2 different 95’s or what am I not understanding? 2 different scanners?regardless my '95 bled out perfectly well without a scanner interface.

You have the iron-body RWAL. The later, aluminum-body RWAL needs a scan tool because there is no bleeder screw.Both my '88 and '89 trucks have a bleeder on the unit and there no need to connect to them with a scanner.
You got lucky. Apparently there wasn't any air trapped in the accumulator circuit.I'll have to look at my scanner for the software date, regardless my '95 bled out perfectly well without a scanner interface. The pedal is high, firm, and the ABS activates as designed.
