Johny Utah Posted January 16, 2014 Report Share Posted January 16, 2014 My radio stopped working on my 2009 Chevy 2500 hd truck. It only has 40,000 miles. I checked the 42 fuse for the radio. It was good. What else could it be? Quote Link to comment Share on other sites More sharing options...
Cordell Posted January 16, 2014 Report Share Posted January 16, 2014 I've replaced pleny of GM radios, but you have to check for power and ground and those have a serial data circuit that triggers the radio to "wake up" coming from the body control module. Does it power up at all? Not play anything? What do you mean by doesn't work? Quote Link to comment Share on other sites More sharing options...

Since you've checked the fuse (I would check all of the fuses since other fuses/modules effect the serial buss)n then you need to pull the radio and check for power and ground. If you can't find a scematic I can post one when I get home. That'll narrow it down to the serial buss or the radio, likely being the radio. Let us know how it goes.
