Nissan Altima (L32) 2007-2012 Service Manual: Power window system
System Diagram
POWER WINDOW LH ANTI-PINCH SYSTEM
System Description
MAIN POWER WINDOW AND DOOR LOCK/UNLOCK SWITCH INPUT/OUTPUT SIGNAL CHART
POWER WINDOW OPERATION
• Power window system is operable during the retained power operation timer after turning ignition switch ON and OFF.
• Main power window and door lock/unlock switch can open/close all windows.
• Power window switches can open/close the corresponding windows.
POWER WINDOW AUTO-OPERATION (LH)
• AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch turns to AUTO.
• Encoder continues detecting the movement of power window motor and transmits to main power window and door lock/unlock switch as the encoder pulse signal while power window motor is operating.
• Main power window and door lock/unlock switch reads the changes of encoder signal and stops AUTO operation when door glass is at fully opened/closed position.
• Power window motor is operable in case encoder is malfunctioning.
RETAINED POWER OPERATION
• Retained power operation is an additional power supply function that enables power window system to operate during the 45 seconds even when ignition switch is turned OFF
Retained power function cancel conditions
• Door CLOSE (door switch OFF)→OPEN (door switch ON).
• When ignition switch is ON.
• When timer time passes (45 seconds).
POWER WINDOW LOCK
Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock switch is ON. This inhibits power window switch operation except with the main power window and door lock/ unlock switch.
ANTI-PINCH OPERATION (LH)
• Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that lowers the door glass 150 mm or 2 seconds when detected.
• Encoder continues detecting the movement of power window motor and transmits to main power window and door lock/unlock switch as the encoder pulse signal while power window motor is operating.
• Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse signal if foreign material is trapped in the door glass.
• Power window switch controls to lower the window glass for 150 mm or 2 seconds after it detects encoder pulse signal frequency change.
OPERATION CONDITION
• When door glass AUTO-UP operation is performed (anti-pinch function does not operate just before the door glass closes and is fully closed) NOTE: Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it may lower.
