SYSTEM DIAGRAM

OPERATION DESCRIPTION

• Turn rear window defogger switch ON while power switch is ON. Then A/C auto amp. transmits rear window

defogger switch signal to BCM.

• BCM transmits rear window defogger control signal to IPDM E/R via CAN communication for approximately

15 minutes.

• IPDM E/R turns rear window defogger relay ON when rear window defogger control signal is received.

• When rear window defogger relay turns ON, IPDM E/R transmits rear window defogger control signal to

VCM via CAN communication. VCM transmits rear window defogger status signal to A/C auto amp. via EV

system CAN communication.

• When rear window defogger is activated, indicator lamp on rear window defogger switch turns ON.

TIMER FUNCTION

• BCM transmits the rear window defogger control signal to IPDM E/R for approximately 15 minutes when the

rear window defogger switch turns ON while power 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 control signal. The same action occurs during timer operation if the

power switch is turned OFF.
