I read this blog and I believe I have the same problem.
However, my car is in my garage at my house in Terre Haute, IN. The closest dealer is in Chicago, IL. After 2 weeks of trying, no truck will come pick it up. i did find a carrier that for $1000 would try to come pick it up to take to Chicago. Any chance someone has some way (laptop?) to help me reprogram the ?body control module? so that the car will wake up ? Briefly, the car powers on, I hear the tron noise, a pump noise, but PRND lights do not come on, instrument cluster does not come on. This happened after car sat for a few weeks then when repowered with a jump pack it kept dying because the jump pack was weak as well from sitting. So I believe the partial boot up may have happened.
