REAR WINDOW DEFOGGER SYSTEM
System DiagramINFOID:0000000001697541
System DescriptionINFOID:0000000001697542
Operation Description
 Turn rear window defogger switch ON when the ignition switch is turned ON. Then controller (auto amp.)
(rear window defogger switch) transmits rear window defogger switch signal to BCM.
 BCM turns rear window defogger relay ON when rear window defogger switch signal is received.
 Rear window defogger and door mirror defogger (with door mirror defogger) are supplied with power and
operate when rear window defogger relay turns ON.
 BCM transmits rear window defogger control signal to IPDM E/R via CAN communication when rear window
defogger operates.
 Rear window defogger ON is displayed when controller (auto amp.) receives signals.
Timer function
 BCM turns rear window defogger 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 (with door
mirror defogger) operate.
 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.
