REAR WINDOW DEFOGGER SYSTEM
System DiagramINFOID:0000000001735602
System DescriptionINFOID:0000000001735603
Operation Description
• Turn rear window defogger switch ON when the ignition switch is turned ON. Then A/C and AV switch
assembly (rear window 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.

BCM • Operates the rear window defogger with the operation of rear window defogger switch.
• Performs the timer control of rear window defogger.
Rear window defogger relay • Operates the rear window defogger and the door mirror defogger with the control signal from
BCM.
A/C and AV switch assembly
(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 prevent
the rear window from fogging up.
Door mirror defogger • Heats the heating wire with the power supply from the heated mirror relay to prevent the door
mirror from fogging up.
