Description & Operation

System consists of a power main relay, power window switches and power window motors for each door. Camry and Camry Solara are equipped with an integration relay that supplies power to power main relay. Avalon and MR2 have body Electronic Control Units (ECU) and Avalon incorporates separate ECUs for driver and front passenger doors. See MULTIPLEX CONTROL SYSTEMS for module communication problems.

On all other models, when ignition is switched to RUN position, battery voltage is supplied through power main relay to power window switches. The power window switch supplies power and ground to power window motors.

Driver's power window switch offers one-touch operation of driver's window. Driver's power window switch also includes a lock-out feature to prevent passengers from operating any of the other power window switches.
