Back-Up Light Switch Diagnosis and Repair - Toyota DIY

Here is my simple yet detailed procedure for diagnosing a bad back-up light switch and the replacement for a large variety of Toyota vehicles and years. In this video, we are working on a Toyota Tacoma with inoperative back-up lights. The diagnostic procedure tests the back-up light circuit, wiring, bulbs, and fuse to confirm that they are all good before definitively condemning the back-up light switch. Then, the switch is easily replaced which is located on the side of the transmission.
