HEADLAMP WASHER OPERATION
With the headlamp washer switch in the ON position, the BCM receives input signal requesting. This input sig-
nal is communicated to the IPDM E/R via the CAN communication. The CPU located in the IPDM E/R controls
the headlamp washer relay coil, which when energized, power is supplied
lthrough 10A fuse (No. 38, located in IPDM E/R)
lthrough IPDM E/R terminal 27
lto headlamp washer relay terminals 2 and 5,
lthrough headlamp washer relay terminal 1
lto IPDM E/R terminal 5,
lthrough headlamp washer relay terminal 3
lto headlamp washer motor terminal 1.
Ground is supplied
lto headlamp washer motor terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, headlamp washer operates.
