I have a chevy 2006 express 3500, when I turn the steering wheel in either direction all the way the dash lights (bat., sercurty, drl,) all light up. and when I center the steering wheel they go off. I get a u1016 code from instrument cluster module. with my power probe tool on the serial data line, the ground light flickers fast. truck will start if steering wheel is not in right postion
