Headlights, brake lights, and turn signals are not working?

The first thing you need to do is check the fuses under the hood and on the interior fuse panel, here is a guide that will help, have the lights on when testing. If the fuses are good, chances are the MICU went out which is common here is the headlamp and running light wiring diagrams so you can see how the system works and how to change out the MICU. To help confirm the failure you can perform a CAN scan which should confirm the MICU failure.

You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:
