U1000 CAN COMM CIRCUIT
BCM
BCM : DescriptionINFOID:0000000003805725
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.

System DescriptionINFOID:0000000003825994
POWER WINDOW OPERATION
 Power window main switch (driver side) can open/close all windows.
 Front & rear power window switch can open/close the corresponding windows.
 Power window system is operable while the retained power operation timer is active after turning ignition
switch ON and OFF.
POWER WINDOW AUTO-OPERATION (DRIVER SIDE)
 AUTO UP/DOWN operation can be performed when power window main switch is turned to AUTO.
 Encoder continues detecting the movement of power window motor and transmits the encoder pulse signal
to power window main switch while power window motor is operating.
 Power window main switch reads the changes of encoder signal and stops AUTO operation when door glass
is at the fully opened/closed position.
 Auto function is inoperable if encoder is malfunctioning.
RETAINED POWER OPERATION
Retained power operation is an additional power supply function that enables power window system to oper-
ate for 45 seconds even when ignition switch is turned OFF.
RETAINED POWER FUNCTION CANCEL CONDITIONS
 Front door CLOSE (door switch OFF) → OPEN (door switch ON).
 When ignition switch is ON again.
 When timer time passes. (45 seconds)
POWER WINDOW LOCK
Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits
power window switch operation except with the power window main switch.

< FUNCTION DIAGNOSIS >
POWER WINDOW SYSTEM
 Pinch foreign material in the door glass during AUTO-UP operation. and it is The anti-pinch function lowers
the door glass 150 mm (5.9 in) or for 2 seconds when detected.
 Encoder continues detecting the movement of front power window motor (driver side) and transmits the
encoder pulse signal to power window main switch while front power window motor (driver side) is operating.
 Resistance is applied to the front power window motor (driver side) rotation that changes the frequency of
encoder pulse signal if foreign material is trapped in the door glass.
 Power window main switch lowers the window glass 150 mm (5.9in) for 2 seconds after it detects encoder
pulse signal frequency change.
OPERATION CONDITION
When front door glass (driver side) AUTO-UP operation is performed (anti-pinch function does not operate just
before the door glass closes and is fully closed)
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it
may lower.
