Service 4 wheel drive ...message

[2-H2's]

I've had my truck in for mods lately & went to pick it up today. The message wasn't there a month ago when I took it in? The vehicle is an '05 SUT, just installed the FabTech lift, two Gobi's, 6 Pia's, dual battery setup, along with new tires & wheels.

I took the truck to the stealership earlier today;

First comment was, "this truck has been recently modified"...No shiat!!!

Second comment was, "no warranty"

My response was; "get Hummer on the telephone, so we can settle this, NOW!!!"

They backed off slightly & decided to look at it. Their first diagnosis was a faulty encoder motor. They replaced it & the message was still present. So now I have an appointment on Monday to bring it back in...Until then…

I pose my question for the gods, messiahs & hummer techs on this forum. Any ideas as to what might be causing this message???
