POWER WINDOW CONTROL SYSTEM Front Passenger Side Index Function does not Operate

DESCRIPTION

The main body ECU (network gateway ECU) detects signals from the front door courtesy light switch. When the ON signal from the front door courtesy light switch is sent to the power window regulator switch assembly via the main body ECU (network gateway ECU) using LIN communication system, the main body ECU (network gateway ECU) will lower the front passenger side door window about 20 mm (0.787 in.) automatically. When the OFF signal from the front door courtesy light switch is detected, the main body ECU (network gateway ECU) will raise the front passenger side door window to the fully-closed position automatically.

CAUTION / NOTICE / HINT

Note


  • When the power window regulator master switch assembly, power window regulator switch assembly and power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized Click here.

  • When the jam protection function malfunctions and prevents the door glass from closing completely, the following procedure can be used to cancel the jam protection function and allow the door glass to be closed*1.


    • Repeat the AUTO UP maintain → jam protection function operation twice in succession*2.

    • The third repeat of the AUTO UP maintain operation will cause the position of the upper edge of the door glass to be relearned, allowing the door glass to be closed.


      • *1: In some cases, the state of the door glass or regulator may prevent the glass from being closed, even in this mode.

      • *2: If any action other that the AUTO UP operation (DOWN operation, IG OFF, timer-operated OFF, index operation, etc.) is performed between the operation of the jam protection function and the AUTO UP maintain, this count will be reset.
