The power window relay is controlled by the smart wiring system (SWS). For troubleshooting, refer to MULTIPLEX CONTROL SYSTEMS article. When the power window switch (main or sub) is operated, the power window motor operates and opens or closes the door window.
A timer function has been provided to allow the door windows to be opened or closed in 30 seconds after the ignition switch is turned from "ON" to "LOCK" (OFF) position when a front door < LH > and < RH > is closed (door switch is OFF). When the lock switch is changed from unlock to lock, the door windows can only be opened or closed by the power window main switch on the driver's side.
If the following types of symptom occur, there may be a fault.
- None of the door windows open or close.
- There are door windows that do not open or close using the power window (main or sub) switch.
- The windows cannot be opened or closed using the power window (main or sub) switch within 30 seconds after the ignition switch is turned from "ON" to "LOCK" (OFF) position.
