Assist power window switch, a component of CAN, performs CAN communication with BCM, seat ECU, tilt ECU, driver power window switch. Passenger controlsassist power window switch button located inside of the assist door to operate power window, mirror, door lock and unlock.
It performs 4 types of operation of manual up/down and automatic up/down operation for 4 power windows.
It performs manual operation of the mirror position by manual switch. (up/down and left/right)
It performs registration and replay of mirror position by the mirror switch up to 2 drivers.
This switch controls power window up/down, automatic up/down from assist side.
Assist's power window switch sends input signal by the manual up/down and automatic up/down switch input. At the same time manual up/down and automatic up/down signals sends to the wires
→ Assist safety window receives the signal and performs manual up/down and automatic up/down functions.
Timer function
Power window switch can be controlled for 30 seconds after the ignition is turned off. This function stops immediately even within 30 seconds if the front door is opened.
Manual control of right outside mirror
If the mirror direction switch (up, down, left and right) is pressed when mirror selection switch on driver power windowswitch is in outside RH under ACC ON condition, then operating signal is sent to assist power window switch through CAN communication.
It can be memorized assist outside mirror position by CAN communication from driver door module. However, RH side mirror position is not registered during the LH side mirror manual switch operation.
Memory is cleared if the battery is removed.
Mirror is returned to the registered position as each position switch is pressed while the ignition 2 is ON.
Memory replay operation will be performed only if the memory is registered.(POS1 or POS2)
If the position switch (POS1 or POS2) is pressed while the memory replay is in operation, the final switch is effective.
Replay inhibit condition
When inhibit “P” switch is OFF
When the ignition 2 is OFF
When RH side mirror switch is pressed
When the vehicle speed is more than 3 km/h
When the memory STOP switch is turned ON
Memory operation
Outside mirror LH position is registered in the driver side power window switch when the ignition is turned off from on.
When door is locked by the keyless, outside mirror position is registered corresponding to the keyless code.
Data related to the memory operation is received from BCM in CAN communication.
Replay operation
When door is unlocked by the keyless under ignition off state, it replays the position corresponding to the keyless code.
Data related to the replay operation is received from BCM in CAN communication on CAN line.
Replay prohibit condition
When the inhibit “P” switch is OFF
When RH side mirror switch is pressed
When mirror switch is pressed after ignition on
When the vehicle speed is over 3km/h
When the memory stop switch is ON
If the position sensor shows no input change (driving for 5 seconds) above 60 mV while the motor is in operation, it automatically stops the operation judging that wire short, motor failure, or sensor failure.
Mirror drive signal cannot be outputted for more than 15 seconds in one direction. (In case of memory replay or manual switch operation)
Monitoring of replay execution time
If replay operation does not complete within 40 seconds from replay starting time, mirror motor stops the output and terminates the replay control.
