"AFS off" repair, Lexus, Toyota, Prius

This video shows a common and fairly typical fault that leads to an “AFS off” warning on the dash of a 2008 Lexus 400h. Details of the repair are shown, and comparison is made to the approach taken at OEM dealerships. The AFS system was designed to provide adaptive front headlight illumination that will respond to differences in vehicle ride height and turning. When the AFS system is disabled for some reason, it reverts to a baseline safe headlight aim and the PCM sends a signal to the dash to flash the AFS off warning. This is an amateur effort, with no guarantees as to accuracy or safety. Do not proceed with any repair of your vehicle if you are not prepared to accept all risks.
