Function

•  The headlight cleaner motor operates when the windshield washer switch is operated with the ignition switched ON (engine off or on) and headlights turned on.
•  When the headlight cleaner motor operates, the headlight cleaner actuator is operated by the hydraulic pressure of the washer fluid pumped from the headlight cleaner motor, and washer fluid is sprayed from the headlight cleaner nozzles.
―  Auto-operation Control
•  When the windshield washer switch is turned on the first time after the headlights are turned on, the headlight cleaner system operates automatically.
―  Manual operation Control
•  The headlight cleaner system operates when the windshield washer switch is turned on twice quickly.
•  The windshield washer switch operation needs to be done within the period of time shown in the figure.

Operation


Auto-operation

1.  When the windshield washer switch is turned on (1), the start stop unit sends a windshield washer switch position signal (ON) to the front body control module (FBCM) as a CAN signal.(2)

2.  When the front body control module (FBCM) receives the windshield washer switch position signal (ON) twice within a certain period of time with the ignition switched ON (engine off or on) and the headlights turned on, it supplies the base current from the internal CPU to the transistor (3), and collector current flows from the internal power supply (4), turning the headlight cleaner relay on.(5)

3.  When the headlight cleaner relay is turned on, current flows from the power supply inside the front body control module (FBCM) to the headlight cleaner motor and the headlight cleaner motor operates, and washer fluid is sprayed from the headlight washer nozzles.(6)

Manual operation

1.  When the windshield washer switch is turned on twice quickly with the ignition switched ON (engine off or on) and the headlights turned on (1), the start stop unit sends a windshield washer operation request signal to the front body control module (FBCM) as a CAN signal.(2)

2.  When the front body control module (FBCM) receives the windshield washer operation request signal twice within a certain period of time, it supplies the base current from the internal CPU to the transistor (3), and collector current flows from the internal power supply (4), turning the headlight cleaner relay on.(5)

3.  When the headlight cleaner relay is turned on, current flows from the power supply inside the front body control module (FBCM) to the headlight cleaner motor and the headlight cleaner motor operates, and washer fluid is sprayed from the headlight cleaner nozzles.(6)
