I own a 2015 GMC Sierra SLT Z71. When I put my truck in reverse, the reverse camera that pops up in the dashboard (the 8" touch screen) is black and says 'Service Rear Vison System'. Does anyone know how to fix this issue? It should be noted that I have not been in any accidents, have not replaced the rear reverse lights or head lights. I do have a LED brake light-bar underneath the tailgate that is plugged into the tow hitch on the truck. I have had the brake light-bar on the truck for almost 6 months now so I don't think that is the issue.
I'm posting the factory service manuals for GMC/GM 2007-2009 trucks as there are a ton of questions around specs and trouble shooting. This manual covers everything you need to trouble shoot and all the specs you need to rebuild/repair your truck.
Hey All, Hoping you guys can point me in the right direction. I have a 2014 Silverado that has recently lost the passenger side low beam. The headlights will turn on when starting the truck and then flicker and the passenger side goes out within about 10 seconds. The driver's side continues to operate as normal and the high beams also operate as normal. If I turn on the headlight switch with the truck not running the headlights will both stay on. Once the truck starts the passenger bulb shuts off. I had this in to the dealer since it was looking like a BCM issue and I have no way of testing or programming a new BCM. They diagnosed and said the BCM was bad. Essentially they replaced the BCM with no results and they replaced the underhood fuse panel with no results. They said when the light quits they are not getting power out of the BCM for that headlight. So it is either a BCM input or something in the BCM. They did find a code (after performing the "repairs") and that code was a "short to ground" code. They did not give me the code number. Has anyone had this? Right now this is the only issue. I've read about ground issues and will check those on Saturday but I am not experiencing any other electrical issues so I am doubting I have a dash ground issue. I appreciate any help you all can give. Thanks, Derek
