Description and operation

Function of Safety Power Window

When driver door power window auto-up switch is operated, safety function is activated.

1.	Safety function condition When detect the force of 100N (using the 10N/mm spring) during the window rising, window is reversed.

Length of window reversing (except holding the auto-up switch)

–	When detect the jamming during the 4mm - 250mm from top of the door. → Window is reversed until 300mm from top of the door.

–	When detect the jamming over the 250mm from top of the door. → Window is reversed until 50mm from jamming position.

Length of window reversing (holding the auto-up switch)

–	When detect the jamming during holding the auto-up switch. → Window is reverse until 25mm from jamming position.

–	Auto-up function is not available during the 5 seconds from above condition. → When holding the auto-up switch, window is operated as a manual-up function. (Safety function is not activated.)

–	When holding the auto-up switch after 5 seconds from above condition. → Window is reverse until 25mm from jamming position.

4.	Safety function is not available area Safety function is not available during the 4mm from top of the door.

2.	Remove the front door trim. (Refer to Body - "Front Door Trim")

3.	Disconnect the motor connector from the motor.

4.	Connect the terminal No.1 and No.2 to battery voltage (12V) and check that the motor operates smoothly when connecting the terminals below. [Safety Window Motor]

5.	Connect the motor terminals directly to battery voltage (12V) and check that the motor operates smoothly. Next, reverse the polarity and check that the motor operates smoothly in the reverse direction. If the operation is abnormal, replace the motor. [Standard Window Motor]

Rear Power Window Motor

1.	Disconnect the negative (-) battery terminal.

2.	Remove the rear door trim. (Refer to Body - "Rear Door Trim")
