through 50A fusible link (letter F , located in the fuse and fusible link box)
to BCM terminal 55,
through 10A fuse [No. 21, 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.
through 10A fuse [No. 12, located in the fuse block (J/B)]
to rear window defogger relay terminal 1.
With the ignition switch turned to ACC or ON position,
through 10A fuse [No. 6, located in the fuse block (J/B)]
to multi-function switch terminal 2.
Ground is supplied
to BCM terminal 52
through body grounds M16 and M70,
to multi-function switch terminal 14
through body grounds M16 and M70,
to IPDM E/R terminals 38 and 51
through body grounds E22 and E43.
When rear window defogger switch in multi-function switch is turned to ON.
Then multi-function switch recognizes that rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signals to AV control unit (without navigation system) or NAVI con-
trol unit (with navigation system) via AV line.
When AV control unit (without navigation system) or NAVI control unit (with navigation system) receives rear
window defogger switch signals, and display on the screen.
Then AV control unit (without navigation system) or NAVI control unit (with navigation system) recognizes that
rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signal to BCM via DATA LINE (CAN H, CAN L).
Then BCM recognizes that rear window defogger switch signal.
Then it sends rear window defogger request signal to IPDM E/R via DATA LINE (CAN H, CAN L).
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 57
through IPDM E/R terminal 51
through body grounds E22 and E43.
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
through condenser terminal 1
to rear window defogger terminal 1
Rear window defogger terminal 2 is grounded through grounds B702.
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 terminals 5 and 7
through fuse block (J/B) terminal 2C
through 10A fuse [No. 8, located in the fuse block (J/B)] and
through fuse block (J/B) terminal 5B
to door mirror (LH and RH) terminal 4.
Door mirror (LH and RH) terminal 8 is grounded through body grounds M16 and M70.
