Headlamp Washers

The headlamp washer is activated when the driver requests windshield washer operation. The CJB receives the driver request via a CAN bus message from the IC. The CJB then checks for an exterior lights active signal and that a low washer fluid level signal is not present.

The CJB outputs a control voltage to a headlamp washer pump relay located in the EJB. The relay is energized by the CJB for a predetermined period to allow the headlamp telescopic washers to operate.

The CJB monitors the driver washer requests and only operates the headlamp washer on every fourth request for windshield washer operation, provided that 10 minutes have elapsed since the last headlamp washer operation. The washer sequence is reset when the headlamps or the ignition is switched off.

NOTE: If a low fluid reservoir level is present, the CJB prohibits headlamp powerwash.
