AUTO OPERATION
The power window AUTO feature enables the driver to open or close the driver's window without holding the
window switch in the down or up position.
The AUTO feature operates on the driver's window.
POWER WINDOW LOCK
The power window lock is designed to lock operation of all windows except for driver's window.
When the lock switch is pressed to lock position, ground of the sub–switches in the power window main switch
is disconnected.This prevents the power window motors from operating.
TIMER FUNCTION
With the timer function, driver power window can be operated for approximately 15 minutes after ignition
switch is turned OFF (positions other than ON). However, the timer will be cancel when a specific signal, such
as driver door close (door switch OFF) → open (door switch ON), or ignition switch OFF → ON, is input.
DRIVER WINDOW ANTI–PINCH FUNCTION
During raising operation of driver power window, if power window main switch detects that foreign object is
pinched, power window lowers approximately 150 mm (5.91 in).
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to power window, it
may lower.
Operation conditions
●Driver door window is between fully-open and just before fully-closed position (when the limit switch is
ON).
●During automatic operation when ignition switch is turned ON.
●During automatic or manual operation when ignition switch is other than ON position (when the timer
operates).

AIR CONDITIONER CONTROLPFP:27500
Overview Air Conditioner LAN Control SystemEJS000TI
The LAN system consists of auto amp., mode door motor, air mix door motor and intake door motor.
A configuration of these components is shown in the diagram below.
System ConstructionEJS000TJ
A small network is constructed between the auto amplifier, air mix door motor, mode door motor and intake
door motor. The auto amplifier and motors are connected by data transmission lines and motor power supply
lines. The LAN network is built through the ground circuits of the three motors.
Addresses, motor opening angle signals, motor stop signals and error checking messages are all transmitted
through the data transmission lines connecting the auto amplifier and three motors.
The following functions are contained in LCUs built into the air mix door motor, the mode door motor and
intake door motor.
●Address
●Motor opening angle signals
●Data transmission
●Motor stop and drive decision
●Opening angle sensor (PBR function)
●Comparison
●Decision (Auto amplifier indicated value and motor opening angle comparison)
OPERATION
The auto amplifier receives data from each of the sensors. The amplifier sends mode door, air mix door and
intake door opening angle data to the mode door motor LCU, air mix door motor LCU and intake door motor
LCU.
The mode door motor, air mix door motor and intake door motor read their respective signals according to the
address signal. Opening angle indication signals received from the auto amplifier and each of the motor posi-
tion sensors are compared by the LCUs in each motor with the existing decision and opening angles. Subse-
quently, HOT/COLD, DEFROST/VENT or FRESH/RECIRCULATION operation is selected. The new selection
data is returned to the auto amplifier.
