When the headlamp washer switch is ON, ground is supplied

to BCM terminal 10

through headlamp washer switch terminal 1

through headlamp washer switch terminal 2

through grounds M71 and M72.
HEADLAMP WASHER OPERATION
When the headlamp washer switch is in ON position with the ignition switch in ON position and the lighting
switch in 2ND position, BCM detects the headlamp washer switch ON signal. It also detects the HEAD LAMP1
and 2 (ON) by BCM combination switch reading function. BCM judges that the condition of headlamp washer
operation meets. And then, BCM sends headlamp washer request signal (ON) through CAN communication.
When receiving headlamp washer request signal (ON), IPDM E/R turns ON headlamp washer relay. And then,
headlamp washer pump operates.
Power is supplied

through headlamp washer relay terminal 2

to IPDM E/R terminal 58,

through headlamp washer relay terminal 5

to headlamp washer pump terminal 1.
Ground is supplied

to headlamp washer pump terminal 2

through grounds E1 and E31.
With power and ground supplied, headlamp washer operates.
INTERLOCKED OPERATION WITH FRONT WINDOW WASHER
When the front window washer switch is in ON position at the every first time of ignition switch ON, with the
ignition switch in ON position and the lighting switch in 2ND position, BCM detects the FR WASHER (ON) and
the HEAD LAMP 1 and 2 (ON) by BCM combination switch reading function. BCM judges that the condition of
headlamp washer operation meets. And then, BCM sends headlamp washer request signal (ON) through
CAN communication.
When receiving headlamp washer request signal (ON), IPDM E/R turns ON headlamp washer relay. And then,
headlamp washer pump operates.
