FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationNKS003WB
System DescriptionNKS003WC
Front wiper relays (HIGH, LOW) are included in IPDM E/R (intelligent power distribution module engine
room).
Front wiper reverse relay is included in relay box-1. Refer to PG-96, "ELECTRICAL UNITS LOCATION" .
Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when switch is turned ON.
BCM controls front wiper LO, HI, and INT (intermittent) operation.
IPDM E/R operates wiper motor according to CAN communication signals from BCM.
Front wiper motor switches LOW speed to/from HIGH speed by BCM function to change polarity.
