- Function Of Safety Power Window When driver door power window auto-up switch is operated, safety function is activated.

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

2.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.

3.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 areaSafety function is not available during the 4mm from top of the door.

1.Initializing of Battery ConnectionWhen the battery power is removed for over 5 minutes, safety power window switch need the initializing.

(2)Initializing methodClose the window in window open position, and holding the switch in window full close position over the 0.2 second.(If start the closing the window in window full close position, initializing could be failed.)

(3)If initialize the safety power window in jamming status, could occur below conditions.

– Safety function is not available

2.Initializing of fail safe mode

(1)If the window moved by compulsion and motor have a problem, power window switch could be entering the fail safe mode for user’s safety.

1.In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (Diagnostic tool).The diagnostic system (Diagnostic tool) provides the following information.

(1)Fault Code Searching : Checking failure and code number (DTC)

(2)Data Analysis : Checking the system input/output data state

(3)Actuation test : Checking the system operation condition

(4)S/W Management : Controlling other features including system option setting and zero point adjustment

2.If diagnose the vehicle by Diagnostic tool, select "DTC Analysis" and "Vehicle".

3.Select the 'Data Analysis' and 'Car model'.

4.Select the 'DDM' to search the current state of the input/output data.

5.To forcibly actuate the input value of the module to be checked, select option 'Actuation Test'.
