DRIVER SIDE POWER WINDOW SYSTEM OUTLINE

id091200684200
• On the basis of the pulse signals from the Hall effect switches in the power window motor, the power window control module in the power window main switch determines the window position and the operation direction. Accordingly, the power window main switch controls the driver-side power window system.
• When the initial position is set before vehicle delivery, the window position and the operation direction are stored in the power window control module in the power window main switch. Thus resetting the initial position is necessary if the battery negative cable, power window main switch connector, or power window motor connector is disconnected.

  Note

  • If the initial position has not been set, the driver-side power window system's auto function, the auto window return function and the precise motion function will not function.
  • See the workshop manual for more information about setting the initial position.

## Fail-safe function

Detection Condition | Fail-safe | Recovery Items
--- | --- | ---
IG switch ON | IG switch OFF
Hall effect switch 1 (for jam-safe and window position detection) operation malfunction • During up/down movement, Hall effect switch 2 pulse detected but Hall effect switch 1 pulse not detected | Automatic operation prohibited | Automatic and manual operation prohibited | During up movement, pulse signals for Hall effect switches 1 and 2 detected normally, and fully closed position and return/non-return ranges redetected
Hall effect switch 2 (for window movement direction detection) operation malfunction • During up/down movement, Hall effect switch 1 pulse detected but Hall effect switch 2 pulse not detected
Pulse signal malfunction detection (Inversion of input signals of, or large phase deviation between, Hall effect switches 1 and 2.) • During up/down movement, difference detected between the direction detection signals from Hall effect switches 1 and 2, and the actual direction
Non-return range downturn malfunction • During up movement, the signal input from Hall effect switch 1 higher than the position stored in the P/W main switch
Hall effect switches 1 and 2 operation malfunction • Hall effect switches 1 and 2 pulse signal not detected after down movement initiated from the fully closed position
