Re: 8.4AN blue screen in reverse
Same problem, 2014 Grand Cherokee, did not come from the factory with a camera so I did the install of the OEM camera kit and harness. Had the dealer register it to my VIN and activate it with their software, but I have nothing but a "check surrounding area" message and a blue screen when shifting into Reverse. Also had no license plate lights (they are powered through the same harness attached with the camera) after installation, but I had 12 volts going to the camera/lights harness. Dealer plugged in the OBD reader and it gave him an error code for camera and lights. Obtained a new camera with harness from the dealer and installed it. Now I have license plate lights again, but the blue screen remains. Downloaded and updated the UConnect software to the latest version, no change. Rechecked all wiring and connections, no change. Confirmed good power to the camera, good ground, and good pin connections at the display connector. Headed to the local auto parts store to ask them to plug in their OBD reader and see if any codes come up. Two bad cameras is possible, but not likely. That leaves either the dealer camera software that activated the camera, or the display unit, as the sources of the problem.
The camera delay function delays turning the camera off for a few seconds after shifting into Drive.
Wbferrara, there's no relay powering the camera, it receives power directly from its own fuse in the engine bay when you press the Start/Stop button. as I recall it's Fuse 85, if you open the cover of the power panel under the hood there's a diagram of all the fuses and relays, or it's in the owners manual.
