to rear window defogger relay terminal 1,

through 15A fuse [No. 32, located in the fuse block (J/B)]

to A/C and AV switch terminal 1,

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

to BCM terminal 55,

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

to BCM terminal 42.
With the ignition switch turned to ON or START position,
Power is supplied

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

to BCM terminal 38.
Ground is supplied

to BCM terminal 49 and 52

through body grounds M35, M45 and M85,

to A/C and AV switch terminal 5

through body grounds M35, M45 and M85,

to IPDM E/R terminals 38 and 60

through body grounds E21, E50 and E51.
When rear window defogger switch in A/C and AV switch is turned to ON,
Ground is supplied

to BCM terminal 9

through A/C and AV switch terminal 16

through A/C and AV switch terminal 5 and

through body grounds M35, M45 and M85.
Then rear window defogger switch is illuminated.
Then BCM recognizes that rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signals to IPDM E/R, display control unit (with navigation system)
or display unit (without navigation system) via DATA LINE (CAN H, CAN L).
When display control unit (with navigation system) or display unit (without navigation system) receives rear
window defogger switch signals, and display on the screen.
When IPDM E/R receives rear window defogger switch signals,
Ground is supplied

to rear window defogger relay terminal 2

through IPDM E/R terminal 52

through IPDM E/R terminals 38 and 60 and

through body grounds E21, E50 and E51.
And then rear window defogger relay is energized.
When rear window defogger relay is turned ON, signals are transmitted.

through rear window defogger relay terminals 5 and 7

to rear window defogger terminal 1
Rear window defogger terminal 2 is grounded through grounds B15 and B45.
With power and ground supplied, rear window defogger filaments heat and defog the rear window.
When rear window defogger relay is turned to ON,
Power is supplied

through rear window defogger relay terminal 7

through fuse block (J/B) terminal 2C

through 15A fuse [No. 8, located in the fuse block (J/B)] and

through fuse block (J/B) terminal 5B

to door mirror defogger (driver side and passenger side) terminal 1.
Door mirror defogger (driver side and passenger side) terminal 2 is grounded through body grounds M35, M45
and M85.

With power and ground supplied, rear window defogger filaments heat and defog the rear window and door
mirror defogger filaments heat and defog the mirror.
CAN Communication System DescriptionAIS004R0
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAIS004RR
Refer to LAN-30, "CAN Communication Unit" .
