POWER WINDOW OPERATION
- Power window system is operable during the retained power operation timer after turning ignition switch ON and OFF.
- Main power window and door lock/unlock switch can open/close all windows.
- Power window and door lock unlock switch RH & rear power window switches LH and RH (crew cab) can open/close the corresponding windows.
POWER WINDOW AUTO DOWN OPERATION (FRONT LH)
- AUTO DOWN operation can be performed when main power window turns to AUTO.
RETAINED POWER OPERATION
- Retained power operation is an additional power supply function that enables power window system to operate during the 45 seconds even when ignition switch is turned OFF
Retained power function cancel conditions
- Front door CLOSE (door switch OFF)-->OPEN (door switch ON).
- When ignition switch is ON.
- When timer time passes. (45 seconds)
Operation Description
- Turn rear window defogger switch ON when the ignition switch is turned ON. Then front air control transmits rear window defogger switch signal to BCM.
- BCM transmits rear window defogger control signal to IPDM E/R via CAN communication when rear window defogger operates.
- IPDM E/R turns rear window defogger relay and heated mirror relay (if equipped) ON when rear window defogger switch signal is received.
- Rear window defogger and door mirror defogger (if equipped) are supplied with power and operate when rear window defogger relay and heated mirror relay (if equipped) turn ON.
- Rear window defogger ON is displayed when signal is received.
Rear Window Defogger System: Component Description
| BCM | Operates the rear window defogger with the operation of rear window defogger switch. Performs the timer control of rear window defogger. |
|---|---|
| Rear window defogger relay | Operates the rear window defogger and the door mirror defogger (if equipped) with the control signal from BCM. |
| Rear window defogger switch | The rear window defogger switch is turned ON. Turns the indicator lamp ON when detecting the operation of rear window defogger. |
| Rear window defogger | Heats the heating wire with the power supply from the rear window defogger relay to prevent the rear window from fogging up. |
| Door mirror defogger (if equipped) | Heats the heating wire with the power supply from the heated mirror relay to prevent the door mirror from fogging up. |
