SYSTEM DIAGRAM

Automatic Air Conditioning System

Except Automatic Air Conditioning System

REAR WINDOW DEFOGGER FUNCTION

• Turn rear window defogger switch ON when the ignition switch turns ON. Then integral switch (rear window

defogger switch) transmits rear window defogger switch signal to display control unit via communication line.
Display control unit transmits rear window defogger switch signal to BCM via CAN communication.

• BCM turns rear window defogger relay ON and transmits rear window defogger control signal to IPDM E/R

via CAN communication when rear window defogger switch signal is received.

• Rear window defogger and door mirror defogger are supplied with power and operate when rear window

defogger relay turns ON.

• IPDM E/R transmits rear window defogger control signal to display control unit via CAN communication.
• Display control unit transmit rear window defogger feedback signal to integral switch (rear window defogger

switch) via communication line, then rear window defogger indicator is illuminated.

REAR WINDOW DEFOGGER AND DOOR MIRROR DEFOGGER TIMER FUNCTION

• BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch

turns ON. It makes rear window defogger, door mirror defogger.

• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns

rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF. 

FRONT WINDOW DEFOGGER FUNCTION

JMLIA5216GB

JMLIA5217GB

DEF-8

< SYSTEM DESCRIPTION >

SYSTEM

• Turns ON front window defogger switch (Front window defogger switch is on A/C control) while ignition

switch is ON, then front window defogger relay is controlled by A/C control to turn front window defogger
ON.

• Front window defogger turns OFF when any of the following condition is detected.
- Battery voltage is under 6 V (Front window defogger turns ON when battery voltage is 10 V or more).
- Electrical power cut freeze signal (permission) is not received from ECM.
- Vehicle power consumption is large.
• Front window defogger turns OFF when vehicle power consumption is large while front window defogger is

operating.

• Front window defogger turns OFF temporarily when rear window defogger is turned ON.
• Front window defogger turns ON again when rear window defogger timer is 4 minutes left. At this time when

vehicle power consumption is large, front window defogger relay LH and RH may turns ON alternately each
10 seconds.

• Front window defogger turns OFF when rear window defogger timer is expired
