System Description

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.

Basic Operation

Opening the power sliding door:
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.

Closing the power sliding door:
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.

Obstruction Detection Function

When opening the sliding doors:
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.

Automatic Closer Function
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.

Fail-safe Function
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 fail-safe 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).

Emergency Stop Function

The emergency stop function automatically stops the sliding doors when any of the switches described below are pressed to prevent someone or something from being pinched in the doors.

Operation:
When the following switches are pressed while a door is moving, the warning buzzer will sound and the sliding door will stop:
- when the OPEN switch is pressed.
- when the CLOSED switch is pressed.
- when the power sliding door switch on the keyless transmitter is pressed.




At this time, the warning buzzer sounds in the following interval, and the doors cannot be operated until the warning buzzer stops.




When the shift lever is in any position other than Park or the vehicle runs more than 3 mph (5 km/h) while the door is opening automatically, the warning buzzer will sound continuously and the door will stop.




When the shift lever is in any position other than Park or the vehicle runs more than 3 mph (5 km/h) while the door is closing, the warning buzzer will sound continuously and the door will continue to close.

When the sliding door main switch is turned off while a door is opening or closing, the door will stop.

NOTE: No warning buzzer will sound.
