POWER STEERING OIL PRESSURE SWITCH
POWER STEERING OIL PRESSURE SWITCH
PFP:49761
Component DescriptionEBS003PS
The power steering oil pressure switch is attached to the power
steering high-pressure tube and detects a power steering load.
When a power steering load is detected, it signals the ECM. The
ECM adjusts the fuel injector pulse width to increase the idle speed
and adjust for the increased load.
CONSULT-II Reference Value in Data Monitor ModeEBS003PT
Specification data are reference values.
ECM Terminals and Reference ValueEBS003PZ
Specification data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

lthrough power window main switch terminal 1 (LHD models) or 7 (RHD models).
Then, the motor raises the window until the switch is released.
WINDOW DOWN
When the driver's window switch in the power window main switch is pressed in the down position, power is
supplied
lto driver side power window regulator terminal 3
lthrough power window main switch terminal 1 (LHD models) or 7 (RHD models)
Ground is supplied
lto driver side power window regulator terminal 1
lthrough power window main switch terminal 2 (LHD models) or 6 (RHD models).
Then, the motor lowers the window until the switch is released.
Front door (Passenger Side)
Ground is supplied
lto power window main switch terminal 19
lthrough body grounds M27 and M70.
NOTE:
Numbers in parentheses are terminal numbers, when power window switch is pressed in the UP and DOWN
positions respectively.
POWER WINDOW MAIN SWITCH OPERATION
Power is supplied
lthrough power window main switch (4, 3) (LHD models) or (4, 5) (RHD models)
lto passenger side power window switch (3, 4).
The subsequent operation is the same as the passenger side power window switch operation.
PASSENGER SIDE POWER WINDOW SWITCH OPERATION
Power is supplied
lthrough passenger side power window switch (1, 2)
lto passenger side power window regulator (1, 2).
Ground is supplied
lto passenger side power window regulator (1, 2)
lthrough passenger side power window switch (1, 2)
lto passenger side power window switch (3 ,4)
lthrough power window main switch (4, 3) (LHD models) or (4, 5) (RHD models).
Then, the ,motor raises or lowers the window until the switch is released.
Rear door
Rear door windows will raise and lower in the same manner as passenger's door window.
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 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.
TIME 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 reset when a specific signal, such
as driver door open (door switch ON)®close (door switch OFF), or ignition switch OFF®ON, is input.
DRIVER WINDOW ANTI–PINCH FUNCTION
During raising operation of driver power window, if door control module detects that foreign object is pinched,
power window lowers approximately 150 mm (5.91 in).
