POWER WINDOW SYSTEM FUNCTION
id091200501200
Manual Open/Close Function
• The door glass opens/closes according to the down (push) or up (pull) operation of the power window main switches and the power window subswitches.
Auto-Open/Close Function
• The driver's door glass automatically moves to a fully-opened or closed position when the driver's window switch on the power window main switches is operated two times, either down (push) or up (pull).
Auto Reverse Pinch Protection Function
• If any object is pinched in the door glass during the auto-close operation, the door glass automatically opens approx. 200 mm.
Two-Step Down Function
• If the switch is lightly pressed (manual open operation) when the door glass is completely closed, the door glass lowers a set distance.(Initial setting is approx. 30 mm.)
• If the manual open operation is performed with the two-step down function enabled, the door glass will always stop momentarily. This is not a malfunction.
• The set distance that the door glass lowers can be changed.(Within a range of approx. 20—100 mm.)
• The two-step down function can be disabled.(Initial setting is enabled)
• If the operation of the auto open/close, manual close, or window obstruction is detected during the two-step down function operation, the operation for each detection is given priority.
• Does not function during IG OFF timer operation.
IG OFF timer function
• Allows operation of the driver's power window for approx. 43 s after the ignition switch has been turned from the ACC to the LOCK position.
Fail-safe function
• When the P/W CM detects a malfunction in the pulse signal (Hall effect switch), the power window system is switched to fail-safe mode to prevent incorrect operations.

Recovery Condition
|
|
Pulse 1 (for pinch and door glass position detection) stopping malfunction
• Pulse 2 detected but pulse 1 is not detected during close or open operation
|
Automatic operation is prohibited
|
Auto and manual operations are prohibited
|
Pulse signals 1 and 2 detected normally during close operation, and redetection of fully-closed position return/non-return ranges
|
|
Pulse 2 (for door glass direction detection) stopping malfunction
• Pulse 1 detected but pulse 2 is not detected during close or open operation
|
|
Pulse signal malfunction detected (inversion of 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
|
|
Non-return range loweringn malfunction
• A signal input from pulse 1 is higher than the position stored in the P/W main switch detected during close operation
