POWER WINDOW SYSTEM OPERATION

id091200101100

Manual Open/Close

• The window 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

• The window automatically moves to a fully-opened or closed position when the power window main switches or the power window subswitches are operated two times, either down (push) or up (pull).

Auto Reverse Pinch Protection Function

• If any object is pinched in the window during auto-close operation, the window automatically opens approx. 200 mm{7.9 in}.

Two-step down function

• If a switch is lightly pushed (manual open operation) when the window is completely closed, the window lowers a set distance. (Initial setting is approx. 30 mm{1.2 in}.)

• If the manual open operation is performed with the two-step down function enabled, the window will always stop momentarily. (This is not a malfunction.)

• The set distance the window goes down can be changed. (Within a range of approx. 20-100 mm {0.79-3.9 in}.)

• 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 two-step down function operation, these other operations are given priority.

• Does not function during IG OFF timer operation.

IG OFF Timer

• Allows operation of the driver’s power window for approx. 45 s after the ignition switch has been turned from the ACC to the LOCK position.

Fail-safe

• The power window system is switched to fail-safe mode to prevent a malfunction when the P/W CM detects a malfunction in the pulse signal (Hall IC).

Malfunction condition

IG SW ON

IG SW OFF

Recovery condition

Pulse 1 (for pinching and door glass position detection) stopping malfunction

•  Pulse 2 pulse detected but pulse 1 not detected when opening or closing

Automatic operation is prohibited

Auto and manual operation 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 of 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

Non-return range downturn malfunction

•  The signal input from pulse 1 is higher than the position stored in the P/W main switch is detected during close operation

Pulse 1 and 2 stopping malfunction

•  Pulse signals 1 and 2 not detected after open operation initiated from the fully closed position
