POWER WINDOW CONTROL SYSTEM
RETAINED POWER FUNCTION
Retained power function is an additional power supply function that enables power window system to operate for 45 seconds after ignition switch turns OFF.
RETAINED POWER FUNCTION CANCEL CONDITIONS
Any of the following condition is satisfied.
•
Front door CLOSE → OPEN.
•
When ignition switch turns ON again.
•
When timer times out. (45 seconds)
LIN COMMUNICATION
Front power window motor (driver side), front power window motor (passenger side), rear power window motor (L/R side), power window main switch and BCM transmit and receive signal by LIN communication.
POWER WINDOW LOCK
Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits rear power window switch operation.
ANTI-PINCH SYSTEM (FRONT DRIVER SIDE)
•
Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that lowers the door glass when detected.
•
CPU continues detecting the movement of power window motor while power window motor is operating.
•
Power window motor controls to lower the door glass for approximately 150 mm (5.91 in) or more after it detects foreign material is trapped in the door glass.
OPERATION CONDITION
•
When door glass 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.
Fail-safe
FAIL-SAFE CONTROL BY POWER WINDOW MOTOR
Power window motor switches power window operation to fail-safe control when malfunction is detected.
Detected item
Judgment condition
Fail-safe operation
Non-Initialized condition
When the motor integrated CPU detect door
glass position non-initialized condition
Auto UP operation (Anti-pinch) is forbidden
Thermal protection
When the motor integrated CPU detect
temperature increases and exceeds threshold
Power window operation is forbidden
Consecutive reverse operation malfunction
When the motor integrated CPU has detected
consecutively 3 times the reverse operation
Auto UP operation (Anti-pinch) is forbidden
FAIL-SAFE CONTROL BY DTC
Power window motor performs fail-safe control when any DTC are detected.
DTC
B2C41–04
Fail-safe
Front power window motor (driver side) operation is stop or inching.
Recovery condition
Initialization completed
A period of time passed
(Temperature returns to normal)
Approximately 10 seconds passed or the
motor integrated CPU detect door glass fully
close position
