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 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.
• Rear window defogger ON is displayed when front air control receives signals.
Timer function
• BCM turns rear window defogger relay ON for appr oximately 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.
