Remote Control Auto Sliding Door Function (Vehicles With Auto Slide Door System)

Switching from all closed to all open

• When a button on the key fob is operated, the signal is sent from the key fob and received by the remote keyless entry receiver.
• The received signal is sent to the BCM and compared with the registered ID number.
• If the ID number matches, the BCM uses communication to send the sliding door open signal to the sliding door control unit.
• When the sliding door control unit receives the sliding door open signal, if the remote control auto sliding door operation enable conditions are met, the warning chime is sounded and the sliding door unlock signal is sent to the sliding door latch control unit using communication.
• When the sliding door latch control unit receives the sliding door unlock signal, it operates the release actuator and unlocks the door lock.
• The sliding door control unit operates the magnetic clutch and the sliding door motor to slide the sliding door in the open direction (At this time, speed control, input reverse, and overload reverse control are executed.)
• When the sliding door is opened to the fully open position, the full-open lock engages, the full-open position is detected with the rotation sensor, the sliding door motor is stopped and the magnetic clutch is controlled ON --> half clutch --> OFF.
• This is held by locking the sliding door at the full open position.

Full open --> full closed operation

• When a button of the key fob is operated, the signal is sent from the key fob and received by the remote keyless entry receiver.
• The received signal is sent to the BCM and compared with the registered ID number.
• If the ID number matches, the BCM uses communication to send the sliding door close request signal to the sliding door control unit.
• When the sliding door control unit receives the sliding door close request signal, if the remote control auto sliding door operation enable conditions are met, the warning chime is sounded and the sliding door full open unlock signal is sent to the sliding door latch control unit using communication and the full open lock is unlocked.
• The sliding door control unit operates the magnetic clutch and the sliding door motor to slide the sliding door in the close direction. (At this time, the sliding door control unit executes speed control, input reverse, and overload reverse control.)
• When the sliding door comes to the half-latch state, the sliding door latch control unit detects the half-latch state through half-latch switch operation. The sliding door latch control unit uses communication to send the half-latch status to the sliding door control unit.
• When the sliding door control unit receives the signal, it switches OFF the sliding door motor and controls the magnetic clutch ON --> half clutch.
• When the sliding door auto closure operates and the full latch is detected, the magnetic clutch is controlled half clutch --> OFF and when the sliding door auto closure operation ends, the door is fully closed.
