I tuned my 2005 Hummer H2 with a u7193 Diablo Sport Tuner and when the programmer starts it writing program; my D.I.C. post a message "SERVICE 4WD" and after the tune is installed it says "REDUCE ENGINE POWER" ...
I followed the instructions where it stated that I had to take 3 fuse out ( INFO, RADIO AMP, and RADIO FUSE) and this what happens... It did the same thing with my last programmer (Hypertech Max Energy)... Is there anything wrong ????
