trailblazer 4wd service light

[onebigburb]

ok guys heres what I've got 04 trailblazer lt 4.2l 4x4. the service 4wd light is on caused by the fact i'm doing a solid axle swap. I have heard you can flash the vcm to fix/trick the comp. into not thinking/looking for the front diff. solenoid/encoder. So which parameter am I looking at to adjust that i'm not sure what part of the software has those parameters.

I'm actually looking for the same thing. I assume a stock 2wd tune would accomplish this. I see several stock tunes but idk if they are 4wd or rwd. Anyone have a stock trailblazer rwd 4.2 tune?

Check the repertory. I just left my actuator plugged in until I get the time of day to dive into it further.
