Headlight Beam Level Warning Circuit: Description

WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

The headlight beam level warning indicator light in the combination meter assembly comes on for approximately 3 seconds when the ignition switch is turned on (IG). The headlight beam level warning indicator light also comes on when the headlight beam level control ECU detects a malfunction.
