System Diagram
INFOID:0000000001712099
System Description
INFOID:0000000001712100
Operation Description
• Turn rear window defogger switch ON when the ignition switch is turned ON. Then 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 (if equipped) ON when rear window
defogger switch signal is received.
• Rear window defogger and door mirror defogger (if equipped) are supplied with power and operate when
rear window defogger relay and heated mirror relay (if equipped) turn ON.
• Rear window defogger ON is displayed when signal is received.
Timer function
• BCM turns rear window defogger relay and heated mirror relay (if equipped) ON for approximately 15 min-
utes when rear window defogger switch is turned ON while ignition switch is ON. It makes rear window
defogger and door mirror defogger (if equipped) 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 (if equipped) OFF. The same reaction also occurs during
timer operation, if the ignition switch is turned OFF.

• 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 (if
equipped)
• Heats the heating wire with the power supply from the heated mirror relay to prevent the door
