 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 via DATA LINE (CAN H,
CAN L).
When display control unit 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 def ogger 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 4.
Door mirror defogger (driver side and passenger side) terminal 3 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 DescriptionINFOID:0000000001328000
CAN (Controller Area Network) is a serial communication li ne 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 UnitINFOID:0000000001328001
Refer to LAN-43, "CAN System Specification Chart".
