POWER WINDOW SYSTEM


id091200012200


Outline

•  A power window system that enables automatic opening/closing of the door glass has been adopted.
•  The driver's side door glass can be opened/closed automatically or manually by operating the power window main switch.
•  Front and rear passenger door glass can be opened/closed manually by operating the power window main switch or the power window sub switches.

Function


Manual open/manual close function

•  When the power window main switch or subswitch is operated for manual operation, the front door glass/rear door glass performs manual open/manual close operation.


Auto open/auto close function

•  When the power window main switch is operated for auto operation, the driver's side front door glass performs auto open/auto close operation. (With auto-open/close function for driver-side window only)
•  When the power window switch of each door is operated for auto operation, the door glass performs auto open/close operation. (With auto-open/close function for all windows)


IG OFF timer function

•  The front door glass/rear door glass can be opened/closed using the power window main switch for approx. 40 s after the ignition is switched from ON (engine on or off) to ACC or OFF.


IG OFF timer cancel

•  The IG OFF timer is canceled when approx. 40 s or more have elapsed since the ignition was switched to ACC or OFF or any door is opened during IG OFF timer operation.


Auto reverse pinch protection function

•  If an obstruction by a foreign object is detected during the auto close operation, the operation changes from close to open.


Fully-closed position record function

•  The power window control module records the fully-closed position of the front door glass/rear glass so that the auto reverse pinch protection function does not operate when the front door glass/rear glass is fully closed.


Construction

•  A power window control module is integrated in the power window main switch.
•  The power window control module controls the power window system based on the pulse signals from the power window motor.

Operation


Driver's side manual open/close operation (Example: close operation)

With auto-open/close function for driver-side window
1.  When the power window main switch is operated for manual close operation, the power window control module receives a manual close signal. (1)
2.  When the power window control module receives a manual close signal, it turns on the close relay. (2)
3.  When the close relay is turned on, the power window motor (RF) starts manual close operation.(3)
am3zzn00005922
With auto-open/close function for all windows
1.  When the power window main switch is operated for manual close operation, the manual close switch is switched (1).
2.  When the power window control module detects a manual close signal, current flows to the close relay (2) and the close relay turns on (3).
3.  When the close relay turns on, the power window motor (driver's side) performs close operation (4).

Operation of front passenger's side and rear manual open/close function from driver's side (Example: front passenger's side close operation)

With auto-open/close function for driver-side window
1.  When the passenger's side switch is operated for close operation by the power window main switch, the close switch is switched (1) and the power window motor (passenger's side) performs close operation (2).
am3zzn00006620
With auto-open/close function for all windows
1.  When the passenger's side switch is operated for manual close operation by the power window main switch, the manual close switch is switched (1).
2.  When the power window control module on the power window subswitch side detects a manual close signal (2), current flows to the close relay (3) and the close relay turns on (4).
3.  When the close relay turns on, the power window motor (driver's side) performs a close operation (5).

Operation of front passenger's side and rear auto open/close function from driver's side (Example: front passenger's auto open operation)

With auto-open/close function for all windows
1.  When the passenger's side switch is operated for auto open operation by the power window main switch, the auto switch and the manual open switch are switched (1).
2.  When the power window control module on the power window subswitch side detects an auto open signal (2), current flows to the open relay (3) and the open relay turns on (4).
3.  When the open relays turn on, the power window motor (driver's side) performs auto open operation (5).

Passenger's side and rear side manual open/close operation (Example: Passenger's side close operation)

With auto-open/close function for driver-side window
1.  When the power window subswitch is operated for manual close operation (1), the power window motor (LF) starts manual close operation.(2)
am3zzn00005924

Power Window System Initial Setting

With auto-open/close function for driver-side window
•  The power window control module records the driver's side door glass position when the switch is pulled and held approx. 2 s after the driver's side door glass is fully closed from the fully opened position with the ignition is switched ON (engine off or on).
With auto-open/close function for all windows
•  The power window control module records the position of each door glass when the switch is pulled and held for approx. 2 s after the door glass is fully closed from the fully opened position with the ignition switched ON (engine off or on).
•  Performing the following procedures will reset the initial setting and disables auto operation. Re-perform the initial setting.
―  Negative battery cable is disconnected
―  Power window main switch connector is disconnected
―  Power window system power supply fuse is removed


Auto Reverse Pinch Protection

1.  When the power window control module detects a change in the pulse signal from the power window motor for 0.3 s or more during the auto close operation, it reverses the power window motor and the door glass opens approx. 200 mm {7.87 in} automatically.


IG OFF Timer Cancel

1.  The power window control module detects the open/close conditions of all the doors based on the door open/close signal sent from the rear body control module (RBCM).

2.  When a door open signal is sent from the rear body control module (RBCM) while the IG OFF timer is on, the IG OFF timer function is canceled.

Fail-safe

•  When the power window control module detects an error in the pulse signal (Hall effect switch), it switches the power window system to fail-safe mode to prevent incorrect operation.

Malfunction condition

Ignition is switched ON (engine on or off)

Ignition switched OFF

Recovery condition

Power window control module detected pulse 1 error (for pinching and door glass position detection) stop malfunction
•  Pulse 2 detected but pulse 1 is not detected during close or open operation
Auto operation is prohibited (Manual operation is enabled) Operation of power window main switch except for the driver's seat is prohibited
Auto and manual operations are prohibited
From a close operation, the power window system returns to normal mode when pulse 1 and 2 signals are received normally, and when the window fully-closed position and the window glass lowering amount during auto reverse are detected
Power window control module detected pulse 2 error (for door glass direction detection) stop malfunction
•  Pulse 1 detected but pulse 2 is not detected during close or open operation
Power window control module detected pulse signal error (inversion of pulse 1 and pulse 2 input signals or large phase deviation between pulses 1 and 2)
•  Difference detected between the direction detected by the signals of pulses 1 and 2, and the actual direction during close or open operation
Power window control module detected pulse 1 error (Non-return range lowering malfunction)
•  During close operation, a pulse 1 signal from the power window motor is detected more than the number of set times even after the window reaches the fully-closed position recorded by the power window main switch.
Power window control module detected pulse 1 and 2 stop malfunction
•  Pulse signals 1 and 2 are not detected for 1 s after the open operation is started from the fully closed position
