WITH AV CONTROL UNIT : System Description
INFOID:0000000003806026
Operation Description
• Turn rear window defogger switch ON when the ignition switch is turned ON. Then multifunction switch (rear
window defogger switch) transmits rear window defogger switch signal to AV control unit via AV communica-
tion. AV 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 AV control unit via CAN communication.
• When receiving the signal, AV control unit indicates rear defogger ON on the display. At the same time, AV
control unit transmits rear defogger control signal to multifunction switch (rear window defogger switch) via
AV communication and illuminates rear defogger switch indicator.
Timer function
• BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch
is turned 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.
