So about a month back I came across an ad for a 2011 4x4 I4 5speed Chevy Colorado with only 117kms and in my price range a unicorn of a truck.... at least it is here in the Maritimes. I absolutely love the truck and its turned a Ford guy into a Chevy guy, This truck is everything I ever wanted out of a Ranger.



Anyways I was really happy to utilize my Alpine deck after three years of it sitting in a box. I bought a wiring harness with that black box to retain my door chimes. I wired up the head unit with my subwoofer, it worked and sounds great. Now it still works but it does some weird things.



First off every so often when I get out of the truck the deck doesn't shut off. Its as if the radio is getting constant power, it doesn't shut off even after ten or fifteen mins either it just stays on. I've forgotten to manually shut off the deck before going into a store or home and I'll come back out to music still playing.



Secondly this is the one that really worries me, I was driving to work in the dark as I always do night shift life. My head lights turned off and came back on right away, my door locks clicked unlocked then locked again, and finally all the idiots lights on my dash flashed the dash said traction stabil control service needed but only for a second then went back to normal. The only light to stay illuminated after everything else was the passlock (Is that what is called?) The little lock symbol for the security system it stays on for a few seconds after everything else happens but does go out. Once though it did not, everything flashed the lock didn't go out then my traction control light came back on with the indicator to service traction control system. I pulled over turned the truck off then back on again and it was fine.



Its like when you first turn the key and start the vehicle all your lights flash like its doing a system check but my truck is doing it while driving down the road. Please help!!!
