HEADLAMP WASHER

HEADLAMP WASHERPFP:28620
Components Parts and Harness Connector LocationBKS002CB
System DescriptionBKS002CC

BCM (Body Control Module) controls headlamp washer operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates headlamp washer pump accord-
ing to CAN communication signal from BCM.
OUTLINE
Power is supplied at all times

to ignition relay (located in IPDM E/R), from battery direct,

through 15A fuse (No. 71, located in IPDM E/R)

to CPU (central processing unit) in IPDM E/R,

through 15A fuse (No. 78, located in IPDM E/R)

to CPU in IPDM E/R,

through 50A fusible link (letter M, located in fuse and fusible link block)

to BCM terminal 55,

through 30A fusible link (letter J, located in fuse and fusible link block)

to headlamp washer relay terminals 1 and 3.
With the ignition switch in the ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

through 10A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38.
With the ignition switch in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52

through grounds M71 and M72,

to IPDM E/R terminals 38 and 60

through grounds E1 and E31.

CAUTION:

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

Turn wiper intermittent dial position to 4 except when checking waveform or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-II. Refer to
