Nissan Rogue Service Manual: System

System Description

SYSTEM DIAGRAM

POWER WINDOW OPERATION

• Main power window and door lock/unlock switch can open/close all windows.
•  Front and rear power window switches can open/close the corresponding windows.

POWER WINDOW AUTO-OPERATION (FRONT DRIVER SIDE)

• 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 power window switch as the encoder pulse signal while power window motor is operating.
•  Power window 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 for 45 seconds even when power switch is turned OFF.

RETAINED POWER CANCEL CONDITIONS

•  Front door CLOSE (door switch OFF) → OPEN (door switch ON).
•  When power switch is ON again.
•  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 SYSTEM (FRONT DRIVER SIDE)

•  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 (5.9 in.) when detected.
• Encoder continues detecting the movement of front power window motor (driver side) and transmits to main power window and door lock/unlock switch as the encoder pulse signal while front power window motor (driver side) is operating.
•  Resistance is applied to the front power window motor (driver side) rotation that changes the frequency of encoder pulse signal if foreign material is trapped in the door glass.
•  Main power window and door lock/unlock switch controls to lower the window glass for 150 mm (5.9 in) after it detects encoder pulse signal frequency change.

OPERATION CONDITION

•  When front door glass (driver side) 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.

Fail Safe

FAIL-SAFE CONTROL

Switches to fail-safe control when malfunction is detected in encoder signal that detects up/down speed and direction of door glass. Switches to fail-safe control when error beyond regulation value is detected between the fully closed position and the actual position of the glass.

It changes to condition before initialization and the following functions do not operate when switched to failsafe control.

•  Auto-up operation
•  Anti-pinch function
•  Retained power function

Perform initial operation to recover when switched to fail-safe mode. However, it switches back to fail-safe control when malfunction is found in power window switch or in the motor.
