The backup camera does not work consistently. While not moving and then shifiting into reverse, the screen does not change or changes to something other than the camera. It usually stops working after several stops and shifts into reverse. Sometimes it goes 2 or 3 days without displaying and then starts working again another day.
I was driving in the freeway beltway 08 when tehran trasmision of my car run out last Saturday 02/04/2018.
I came home last night at about 9:30 pm and parked the car in the garage. This morning at 7:30 am I went into the garage and heard a buzzing sound coming from near the rear wheels of the car. My best guess was the fuel pump was still running (I had had a different problem with a fuel pump not running when the ignition was turned on with a 2000 Jaguar about a year ago). I turned the ignition on and off without cranking the engine, the buzzing continued. I started the 4runner, ran it for about 20 seconds, and shut the engine off. Buzzing stopped.
