Component Parts and Harness Connector LocationINFOID:0000000001704535
System DescriptionINFOID:0000000001704536
• Front wiper relays (front wiper relay, front wiper high relay) are located in the 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.
OUTLINE
Power is supplied at all times• to ignition relay, located in IPDM E/R, from battery directly,
• through 40A fusible link (letter g, located in fuse and fusible link box)
• to BCM terminal 70,
• through 30A fuse (No. 39, located in IPDM E/R)
• to front wiper relay located in IPDM E/R
• through 15A fuse (No. 52, located in IPDM E/R), and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R.
When ignition switch is in ON or START position, power is supplied • through ignition relay (located in IPDM E/R)
• to front wiper relay (located in IPDM E/R), and

• The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by the BCM (body control module) when switch is turned ON.
• The BCM controls rear wiper ON and INT (intermittent) operation.
Power is supplied at all times
• through 40A fusible link (letter g , located in fuse and fusible link box)
• to BCM terminal 70.
With the ignition switch in ON or START position, power is supplied
• through 15A fuse [No. 4, located in the fuse block (J/B)]
• to combination switch terminal 2
• through 10A fuse [No. 6, located in the fuse block (J/B)]
• to BCM terminal 38.
Ground is supplied
• to BCM terminal 67, and
• to combination switch terminal 12
• through grounds M57 and M61.
REAR WIPER OPERATION
When the ignition switch is in the ON or START position, and the rear wiper switch is in the ON position, the
BCM detects a rear wiper ON request through the combination switch (wiper switch) reading function and con-
trols the rear wiper motor as follows.
Power is supplied
• through BCM terminal 55
• to rear wiper motor terminal 1.
Ground is supplied
• to rear wiper motor terminal 3
