2006 chevy trailblazer_lt
Ok, kinda an odd problem. My diagnostics jack under the dash of my '06 TB LT not only shows no codes, but does not power up the code reader. I get the random traction control failure, so there should be something. Is it possible for the car to run with a dead or bad computer? Second question, HOW DO I GO ABOUT CHANGING MY BATTERY WITHOUT KILLING THE CAR?!?
