No.1 DOOR GLASS DOES NOT MOVE UP AND DOWN IN AUTOMATIC MODE [POWER WINDOW SYSTEMS (AUTO-OPEN/CLOSE FUNCTION)]

• The automatic function and the IG OFF timer function do not operate while the power window switch is in fail-safe mode. The fail-safe operates when sensor 1, and/or sensor 2, and/or the sensor power supply malfunctions.

• Sensor 1 and/or 2 malfunction

― When the door glass is moving up and down, the power window switch cannot sense a pulse signal from sensor 1 during the time it senses 5 pulses (2.5 cycles) from sensor 2.

― When the door glass is moving up and down, the switch cannot sense a pulse signal from sensor 2 during the time it senses 5 pulses (2.5 cycles) from sensor 1.

― There are three abnormal pulses in a pulse signal while the door glass is moving up or down.

― There are 20 cycle pulses from a closed position while the door glass is moving up.

― There is no pulse signal for 1 s after the door glass is moved down.
