REAR WIPER AND WASHER SYSTEMPFP:28710
Component Parts and Harness Connector LocationNKS00333
System DescriptionNKS00334

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 rear wiper ON and INT (intermittent) operation.
Power supplied at all times

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

to BCM terminal 55,

through 15 A fuse [No. 22, located in fuse block (J/B)]

to BCM terminal 42.
When ignition switch ON or START position, power is supplied

through 15 A fuse [No.1, located in fuse block (J/B)]

to BCM terminal 38,

through 10 A fuse [No. 84, located in IPDM E/R (intelligent power distribution module engine room)]

to combination switch terminal 14.
Ground is supplied

to BCM terminals 49 and 52

through grounds M35, M45 and M85,

to combination switch terminal 12

through grounds M35, M45 and M85.
REAR WIPER OPERATION
When the wiper switch is in rear wiper ON position, BCM detects rear wiper ON signal by BCM wiper switch
reading function.
BCM operates rear wiper motor, power is supplied
