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.
