I removed my tailgate (and backup camera) to load a truck camper. Now none of the truck cameras work. Does anyone know a work around to trick the truck into thinking the backup camera is installed so I can use the other cameras?
Hello. That is an excellent question. It's a very common issue that people run into when they remove their tailgate for a truck camper or for a work-related reason.
The reason your other cameras are not working is that the truck's computer, or the Body Control Module (BCM), sees the missing tailgate camera as a fault in the system. The BCM is programmed to expect a signal from all of the cameras at all times. When it doesn't receive that signal, it will disable the entire camera system as a safety measure.
Unfortunately, there is no simple "work around" to trick the truck into thinking the backup camera is installed. The system is too complex for a simple hack. However, you do have a few options to get your other cameras working.
1. Relocate the camera. This is the most common solution. You can take the backup camera off the tailgate and plug it into the truck's wiring harness. You can then mount the camera somewhere on the back of the truck, like on the bumper or the hitch. This will allow the BCM to see the camera and will turn the rest of the camera system on.
3. Purchase a tailgate camera relocation kit. There are many aftermarket companies that sell these kits. They typically include a bracket for the camera and a wiring harness that allows you to relocate the camera to a different position.
3. Have the BCM reprogrammed. A GMC dealership or a professional with the right equipment can reprogram the BCM to ignore the missing tailgate camera. This is a more permanent solution, but it will cost you some money.
The best solution for you is to relocate the camera. It's a simple and effective way to get your camera system working again. You can then put the camera back on the tailgate when you remove the truck camper.
