Backup camera not working on my 2004 after messing with the amp and wires in trunk
Title pretty much says it all. About a week ago I pulled the passenger side trunk lining away so I could access & remove the amp and visually inspect the wiring to the amp because my subwoofer wasn't working. I also dug around under the rear deck where the subwoofer is mounted trying to trace what wires went where. I didn't find any obvious problem with the sub wiring so I remounted the amp, plugged everything back in and magically it worked again!
After buttoning everything back up, I went to back out of the parking spot my car was parked in and noticed my backup camera wasn't working anymore
The screen does still work... climate control, audio... I assume the GPS still works but I have the screen set to be turned off unless I push the GPS button or push the climate or audio buttons. Because I have the GPS "turned off", the screen is normally off but would turn on when the car is put into reverse. Similarly, if I had the audio or climate controls up on the screen already, it would switch to the backup camera when in reverse... but it doesn't. The screen stays on the audio or climate screen after shifting into reverse, or stays off if I don't have either of those screens pulled up already. So it seems like the screen in the dash isn't receiving any signal whatsoever from the reverse camera, since it doesn't even change to a black screen or anything when shifting into reverse.
Can anyone tell me if there's a fuse that's dedicated strictly to the reverse camera? If not, can anyone tell me which specific wires (and what color??) run to the camera and where they're located? I figure it has to be a wire/set of wires in one of the two areas I was messing around in... either the rear deck or passenger side of the trunk.
Update... just for kicks I tried to turn my GPS on today and all I got was a black screen. Whatever I disconnected that is affecting the backup camera is clearly linked to the GPS system
Where is this circuit/fuse block located on a ‘04? After pulling the amplifier to have it rebuild the navigation screen is blank and the backup camera doesn’t work. Hopefully both work when I reinstall the amplifier but if the backup camera doesn’t I’d like to test the fuse/circuit. Thanks in advance for your help. [/QUOTE]
I had an odd fix on my SC430 where I needed to eject the GPS disk and reinsert to get the system restarted. May want to try this. Same symptom, black screen.
The circuit panel is on the drivers side under the left access cover(on floor). After installing the amplifier the DVD booted up and the amplifier, backup camera and all navigation functions properly. I didn’t have to access the circuit but am appreciative that the diagram was posted and glad the DVD didn’t need to be ejected to start working again.
