I recently changed the battery to my car and now the backup camera does not work. Also, the display button doesn’t work. I press the display button and nothing happens
My car has 64000 miles.
My car has an automatic transmission.
If these two malfunctions did not start the instant you installed a new battery, they are probably not related to the battery. The camera is activated in reverse which means the circuit goes through the neutral start switch. That switch has been one failure point reported for this system. With regard to both issues, a circuit trace must be performed to pinpoint the interruption whether it is in a switch, wiring, fuse, module, and so forth. You can perform a circuit trace by using the wiring diagram in the Factory Service Manual and a basic meter.
