Window lock switch circuit
CIRCUIT DESCRIPTION
The window lock switch circuit can be checked using the DTC check (refer to DI±1904).
The window lock switch is built in the driver door ECU. Voltage applied to the WLSW terminal of the driver
door ECU is shut off when the window lock switch is turned to the LOCK position. Thus the power main relay
stops power supply to the other power window control switches.
