System Description
BACKGROUNDThe power sliding door system has a number of electrical and mechanical components that must work in synchronization with each other for the doors to open and close properly.
COMPONENTS
Power Sliding Door Control Unit (behind rear inner trim panel)
This unit receives inputs from the switches and sensors in the sliding door system and from B-CAN. It outputs to the slide motor, release actuator, and closer motor to control the movement of the doors. It also controls the sliding door beeper and indicator.
Slide Motor (behind rear inner trim panel)
This motor moves the door in both directions. It includes a power slide door pulser, an electromagnetic clutch and a cable tension adjuster.
- Power Slide Door Pulser (A)-The power slide door pulser generates pulses that are sent to the power sliding door control unit as the sliding door moves. The power sliding door control unit uses these pulses to determine the speed and position of the door.
- Electromagnetic Clutch (B) This clutch engages the motor to the sliding door cables.
Remote Control Assembly
This assembly operates cables that release the front and rear slide door latches, pulls the inner handle lower roller latch release cable, triggers the 3 remote control switches, and activates the fail-safe lever cable. The assembly includes the remote control switches, the door lock actuator, the door lock, the child-proof lock, and the inside door handle linkage.
- Remote Control Switch 1 (A)-This switch signals the power sliding door control unit that the outside door handle is being pulled or the inside door handle is being pulled toward the open direction while the child safety lock is OFF.
- Remote Control Switch 2 (B)-This switch signals the power sliding door control unit that the inside door handle is being pulled toward the close position.
- Remote Control Switch 3 (C)-This switch signals the power sliding door control unit that the inside door handle is being pulled toward the open position while the child safety lock is ON. This switch is used for safety reasons because remote control switch 1 is not actuated when the child safety lock is ON and the inner handle is pulled toward the open position.
Outer Handle Crank Assembly
This assembly operates the lower roller latch cable when the inner handle lower roller latch release cable is pulled by the remote control assembly, the outer handle cable A is pulled by the outer handle or the release actuator is operated. This assembly also operates the outer handle cable B when the outer handle cable A is pulled by the outer handle or the release actuator is operated. This assembly includes the release actuator.
Release Actuator (A)-When the dashboard switch, the remote transmitter, or either the inside or outside door handle is used to open or close the door, the release actuator rotates the outer handle crank assembly linkage, pulling the lower roller latch cable and the outer handle cable B.
Rear Latch Assembly
This assembly mechanically latches the rear of the door in the closed position. It contains the closer motor, the half-latch/full-latch switch, the base position switch, ratchet switch, and the fail-safe lever.
- Closer Motor (A)-This motor moves the latch from the half-latched to the fully latched position to complete closing the door
- Half-Latch Switch/Full-Latch Switch (B)-These switches signal the power sliding door control unit that the door has reached the half-latched position and the fully latched position-the door is fully closed
- Base Position Switch (C)-This switch signals the power sliding door control unit that the closer motor is in its normal, off position.
- Ratchet Switch (D)-This switch provides a confirmation signal to the control unit that the operation of the half-latch and full-latch switches is accurate
- Fail-safe Lever (E)-This lever mechanically disconnects the closer motor from the door latch. See Emergency Stop Operation.
Lower Roller Latch and Stopper Assembly (attached to lower front of slide door)
This assembly is attached to the lower roller's bracket. The lower roller latch latches the door in the open position when it is fully opened. The lower roller stopper stops the door at the "open window" position for safety. It contains the lower roller latch and the lower roller lever as well as the lower rollers.
Sliding Door Power Window Regulator Assembly
This assembly moves the sliding door window in the window run channels, actuates the sliding door window position switch and pulls the lower roller stopper cable. It contains a power window motor, position plate, and sliding door window position switch.
Sliding Door Window Position Switch-This switch signals the power window control unit that the window is open at about 4 inches (about 100 mm) or more.
Front Latch Assembly
This assembly mechanically latches the front of the door in the closed position.
Rear Latch Cable
This cable is routed between the remote control assembly and the rear latch assembly. It is pulled by the remote control assembly and releases the rear latch to open the door.
Front Latch Cable
This cable is routed between the remote control assembly and the front latch assembly. It is pulled by the remote control assembly and releases the front latch to open the door.
Fail-safe Lever Cable
This cable is routed between the remote control assembly and the latch assembly. It is pulled by the remote control assembly and activates the fail-safe lever.
Outer Handle Cable A
This cable is routed between the outer slide door handle and the outer handle crank assembly. It is pulled by the outside handle and rotates the linkage of the outer handle crank assembly.
Outer Handle Cable B
This cable is routed between the outer handle crank assembly and the remote control assembly. It is pulled by the outer handle crank assembly and rotates the linkage on the remote control assembly.
Lower Roller Latch Cable
This cable is routed between the outer handle crank assembly and the lower roller latch assembly. It is pulled by the outer handle crank assembly and releases the lower-roller latch.
Inner Handle Lower Roller Latch Release Cable
This cable is routed the remote control assembly and the outer handle crank assembly. It is pulled by the remote control assembly and rotates the linkage on the outer handle crank assembly.
Lower Roller Stopper Cable
This cable is routed between the power window regulator and the lower roller lever. It is pulled by the power window regulator when the window is about 4 inches (about 100 mm) from the top and it pulls the lower roller stopper.
SWITCHES AND INDICATORS
Main Switch
This switch, when it is OFF, turns off the power slide function of the door, and disables the sliding door beeper The doors can only be opened and closed manually The closer function will continue to operate once the door is manually moved to the half-latched position
Power Sliding Door Switches
There is one rocker switch for each door Each switch signals its respective power sliding door control unit that the driver wants to open or close that door
Sliding Door Indicator (EX and EX with Leather)
This indicator normally lights for about 2 seconds when the ignition switch is turned to ON (II) If it comes on at any other time, it is signaling the driver that there is a problem with the power sliding door system The door with the problem will no longer operate electrically, only manually The technician can use this indicator to read out trouble codes stored in the power sliding door system.
NOTE: Touring models use the MID to inform the driver of a fault in the power sliding door system.
Sliding Door Beeper
This beeper alerts the driver and occupants that the sliding door system requires attention for safety reasons.
