WITH AUTO A/C : System Description
OPERATION DESCRIPTION
• BCM detects that the rear window defogger switch turns ON when the ignition switch is ON, and then transmits the rear window defogger switch signal to IPDM E/R via CAN communication for approximately 15 minutes.
• IPDM E/R turns rear window defogger relay ON when it receives the rear window defogger switch signal.
• The power is supplied to the rear window defogger and door mirror defogger when the rear window defogger relay turns ON.
• When rear window defogger is activated, indicator lamp on rear window defogger switch turns ON.
TIMER FUNCTION
• BCM transmits the rear window defogger switch signal to IPDM E/R for
approximately 15 minutes when the
rear window defogger switch is turns ON while ignition switch is ON. Then, IPDM
E/R activates rear window
defogger and door mirror defogger.
• The timer is cancelled if the rear window defogger switch is pressed again during timer operation. BCM stops the output of rear window defogger switch signal. The same action occurs during timer operation if the ignition switch is OFF.
