Power Sliding Doors
System Description
The power sliding doors can automatically be opened and closed by operating the driver’s switch, the inner and outer
handles on either sliding door, or the keyless transmitter. The power sliding doors have two safety functions for
safeguarding passengers: one is the obstruction detection function, and the other is the emergency stop function.
The power sliding doors are also equipped with a closing system that enables the doors to close automatically when
the doors are half latched.
The power sliding doors have a self-diagnosis function and a fail-safe function. If an electrical malfunction occurs, the
doors can still be opened and closed manually, and the self-diagnosis function can still be activated.
With the shift lever in Park, turn on the main switch on the power sliding door switch, then perform one of these
operations:
• Press the OPEN button on the power sliding door switch once.
• Pull either of the inner or outer door handles once. (Child safety lock must be off for inner handle to open the door).
• Press the sliding door button on the keyless transmitter once.
First, the release motor unlatches the power sliding door, then the slide motor turns toward the OPEN side, and the
door moves from the fully-closed position to the fully-open position. (The slide motor revolution sensor determines
the fully-open position by counting the pulse of the slide motor.) Once the door is fully open, the system shuts down.
With the main switch on the power sliding door switch still on, perform one of these operations:
• Press the CLOSE button on the power sliding door switch once.
• Pull either of the inner or outer door handles once. (Child safety lock must be off for inner handle to open the door).
• Press the sliding door button on the keyless transmitter once.
First, the slide motor turns toward the CLOSE side. The latch switch on the latch position switch turns on and
determines if the door is half latched. The closer motor is energized to complete the latching procedure.
A slide motor revolution sensor in the sliding door motor outputs pulses at a constant rate. When something is
pinched in the sliding door, the pulse rate changes. The control unit detects this and then stops the motor, sounds the
buzzer 3 times, and reverses its direction. The door will then open automatically at the same rate it would normally
open.
If the shift lever is shifted into any position other than Park or the vehicle speed exceeds 3 mph (5 km/h) while a door is
closing, the control unit will stop the door motor momentarily, and then continue to close the door completely.
When the main switch on the power sliding door switch is on, the automatic close function will work regardless of
whether the door is closed manually or with the switch. When the door is commanded to close, the latch position
switch turns on when the door is half latched. The closer motor is then energized to complete the latching procedure.
When a power sliding door is in the half-latched position, the obstruction detection function is off. If the corresponding
power sliding door control unit receives any signal from the dash switch, the remote control switch (inner or outer
sliding door handles), or the factory keyless receiver while in the half-latched position, the control unit sounds the
buzzer 3 times and activates the release motor. The release motor pulls the failsafe lever to mechanically disengage
the closer motor from the latch. Once the latch and the closer motor are disengaged, the slide motor will partially open
the door (about 1 ft).
