FRONT WIPER AND WASHER SYSTEM
FRONT WIPER AND WASHER SYSTEM
Component Parts and Harness Connector LocationINFOID:0000000001328542
System DescriptionINFOID:0000000001328543
 All front wiper relays (HI, LO) are included in IPDM E/R (intelligent power distribution module engine room).
 Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals.
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.
OUT LINE
Power is 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,
 through 30 A fuse (No. 73, located in IPDM E/R)
 to front wiper relay, located in IPDM E/R,
 through 15 A fuse (No. 78, located in IPDM E/R) and
 through 10 A fuse (No. 71, located in IPDM E/R)
 to CPU located in IPDM E/R.
When the ignition switch is ON or START position, power is supplied
 to ignition relay located in IPDM E/R, from battery direct,
 through 15 A fuse [No. 1, located in fuse block (J/B)]
 to BCM terminal 38,
 through ignition relay, located in IPDM E/R
 to front wiper relay, located in IPDM E/R
 to front wiper high relay, located in IPDM E/R and
 to CPU located in IPDM E/R,
