System Description

INFOID:0000000006164628

Operation Description

• When rear window defogger switch is turned ON while ignition switch is ON, the front air control (rear win-

dow defogger switch) transmits rear window defogger switch signal to BCM.

• BCM transmits rear window defogger control signal to IPDM E/R and display unit via CAN communication

when rear window defogger operates.

• IPDM E/R turns rear window defogger relay and heated mirror relay ON 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 and heated mirror relay turn ON.

• Rear window defogger ON is displayed when signal is received.

Timer function

• BCM turns rear window defogger relay and heated mirror relay ON for approximately 15 minutes when rear

window defogger switch is turned ON while ignition switch is ON. It makes rear window defogger and door

mirror defogger operate.

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

rear window defogger relay and heated mirror relay OFF. The same reaction also occurs during timer opera-

tion, if the ignition switch is turned OFF.

• Performs the timer control of rear window defogger.

Rear window defogger relay

• Operates the rear window defogger and the heated mirror relay (if equipped) with the 

control signal from BCM.

Front air control (rear window defogger 
switch)

• The rear window defogger switch is turned ON.
• Turns the indicator lamp ON when detecting the operation of rear window defogger.

Rear window defogger

• Heats the heating wire with the power supply from the rear window defogger relay to pre-

vent the rear window from fogging up.

Door mirror defogger (if equipped)

• Heats the heating wire with the power supply from the heated mirror relay to prevent the
