POWER WINDOW CONTROL MODULE

id091200010800


Purpose


Driver's side

•  Controls the driver's side power window system based on the power window main switch operation signal and power window motor (driver's side) pulse.


Passenger's side and rear side

•  Controls the passenger's side and rear power window system based on the power window subswitch operation signal and power window motor (LF/LR/RR) pulse.


Function

•  When the power window control module receives a power window main switch operation signal, it turns on/off the open/close relay.
•  The power window control module detects the power window motor operation status based on the pulse from the power window motor.

Structure/Construction

•  The power window control module are built into the power window main switch and power window subswitch.

Operation

Power window control module
•  The power window control module detects the motor rotation speed and rotation direction based on pulse 1 and 2 from the power window motor.

Fail-safe

•  When power window control module detects a pulse (Hall effect switch) error, it switches the power window system to fail-safe mode to prevent incorrect operation.

Malfunction condition

Ignition is switched ON (engine off or on)

Ignition is switched off

Recovery condition
Power window control module detected pulse 1 error (for pinching and door glass position detection) stop malfunction
•  During close or open operation, pulse 1 cannot be detected while pulse 2 is detected
•  Auto operation is prohibited (Manual operation is enabled) Operation of power window main switch except for the driver's seat is prohibited
Auto and manual operations are prohibited
Pulse signals 1 and 2 are received normally during up operation, and lowering amount is detected when door glass is fully closed and during automatic reverse operation
Power window control module detected pulse 2 error (for door glass direction detection) stop malfunction
•  During close or open operation, pulse 2 cannot be detected while pulse 1 is detected
Power window control module detected pulse signal error (inversion of pulse 1 and pulse 2 input signals or large phase deviation between pulses 1 and 2)
•  Difference detected between the direction detected by the signals of pulses 1 and 2, and the actual direction during close or open operation
Power window control module detected pulse 1 error (Non-return range lowering)
•  During close operation, pulse 1 signal from the power window motor detected more than set times even after the window reached the fully-closed position recorded by the power window control module.
Power window control module detected pulse 1 and 2 stop malfunction
•  Pulse signals 1 and 2 are not detected for 1 s after the open operation is started from the fully closed position
