HINT:

*1: When the AFS indicator light does not come on or blink despite the symptom being occurring, check the battery voltage.
*2: Check if the headlight swivel motor turns smoothly by hand. If the motor does not turn, replace it with a new one. If the motor still does not turn, replace the headlight assembly with a new one.
*3: Before beginning diagnosis, check that the AFS setting is ON.
