Checking While The Headlights Are On

If any of the defects below are found, replace the controller.

WARNING: While the headlights are on, do not touch the headlight bulbs. There is a high risk of scalding, as the headlight bulb will become extremely hot.
NOTE: Ensure that the headlight control system and its circuit (power supply control at engine start and during steady illumination, high-voltage generating circuit, etc.) are working normally. Then check whether internal breakage has occurred in the controller. However, some internal breakage may not be able to be found
LIGHT CHECK

Check how the lights illuminate. 
Turn on and off the headlights several times when they are cold and warm. Observe how the headlights illuminate.
Observe the headlights until they illuminate steadily (approximately five minutes after switching on them). Check that the headlights do not flash or flicker.
Turn on the headlights for thirty minutes. Check that the brightness is the same between right and left lights. Also check that the headlights do not flash or flicker.
