Opening a Door with the Power Sliding Door Switch 

To open a door electrically:

  1. If the Power Sliding Door Switch is used, the switch sends a signal to the power sliding door control unit for that door.
  2. The power sliding door control unit sends a signal to the release actuator to unlatch the door.
  3. The release actuator rotates the linkage on the outer handle crank which pulls the front and rear latch cables. This releases the front and rear latches, mechanically unlatching the door.
  4. The power sliding door control unit then activates the electromagnetic clutch and starts the slide motor. The slide motor moves the cables that move the door.
  5. The power slide door motor pulser senses the movement of the slide motor, and sends pulses to the power sliding door control unit. The control unit uses these pulses to judge the speed and the position of the door.
  6. When the power sliding door control unit judges that the door is fully open, it turns off the slide motor and the electromagnetic clutch.
  7. The lower roller latch, located in the lower roller assembly, secures the door in the fully open or open window position.

    Opening a Door with the Power Sliding Door Transmitter 

    To open a door electrically:

    • The Main switch must be ON.
    • If the ignition switch is ON (II), the shift lever must be in P or the foot brake must be ON or parking brake must be ON, and the vehicle speed, including the wheel speed sensor, indicated zero.
    • The fuel fill door must be closed (left door only)
  8. The Immobi/Keyless unit sends an open message to the power sliding door control unit for that door
  9. If the slide door is locked, the power slide door control unit sends a message to the MICU to unlock the slide door and the front door on the same side of the vehicle.
  10. When the door is detected as unlocked, the power sliding door control unit sends a signal to the release actuator to unlatch the door.
  11. The release actuator rotates the linkage on the outer handle crank which pulls the front and rear latch cables. This releases the front and rear latches, mechanically unlatching the door.
  12. The power sliding door control unit then activates the electromagnetic clutch and starts the slide motor. The slide motor moves the cables that move the door.
  13. The power slide door motor pulser senses the movement of the slide motor, and sends pulses to the power sliding door control unit. The control unit uses these pulses to judge the speed and position of the door.
  14. When the power sliding door control unit judges that the door is fully open, it turns off the slide motor and the electromagnetic clutch.

    Opening a Door with the Inside or Outside Handle 

    To open a door electrically:

    • The Main switch must be ON.
    • If the ignition switch is ON (II), the shift lever must be in P or the foot brake must be ON or parking brake must be ON and the vehicle speed, including the wheel speed sensor, indicated zero.
    • The door must be unlocked, and the fuel fill door must be closed (left door only).
  15. The inside door handle is mechanically linked to the remote control assembly. The outside door handle is linked via the outer door handle cable.
    • Inner handle, child safety lock OFF-The inner handle rotates the linkage on the remote control assembly which pulls the front and rear latch cables. This releases the front and rear latches, mechanically unlatching the door.
    • Inner handle, child safety lock ON-The inner handle rotates the linkage on the remote control assembly which only pulls the fail safe cable; the front and rear latch cables are mechanically disengaged from the linkage.
    • Outer handle-The outer handle pulls the outer handle cable which rotates the outer handle crank. The outer handle crank pulls the front and rear latch cables. This releases the front and rear latches, mechanically unlatching the door.
  16. Remote control switch 1 or 3 is opened by the rotated linkage on the remote control assembly.
    • Inner handle, child safety lock OFF-The linkage on the remote control assembly closes remote control switch 3, the rear latch cable is pulled activating the ratchet switch. The power slide door control unit is signaled by the ratchet switch and the child lock switch to open the door.
    • Inner handle, child safety lock ON-The linkage on the remote control assembly closes remote control switch 3, but the rear latch cable is mechanically disengaged preventing the ratchet switch from activating. The power slide door control unit is signaled by the ratchet switch and the child lock switch NOT to open the door and the operation ends.
    • Outer handle-The linkage on the remote control assembly closes remote control switch 1, signaling the power slide door control unit to open the door.
  17. The power sliding door control unit sends a signal to the release actuator to unlatch the door.
  18. The release actuator rotates the linkage on the outer handle crank which pulls the front and rear latch cables (This keeps the front and rear latches mechanically unlatched in the event that the inner or outer handle is not held long enough for the electromagnetic clutch and slide motor to open the door).
  19. The power sliding door control unit then activates the electromagnetic clutch and starts the slide motor. The slide motor moves the cables that move the door.
  20. The power slide door motor pulser senses the movement of the slide motor, and sends pulses to the power sliding door control unit. The control unit uses these pulses to judge the speed and position of the door.
  21. When the power sliding door control unit judges that the door is fully open, it turns off the slide motor and the electromagnetic clutch.
  22. The lower roller latch, located in the lower roller assembly, secures the door in the fully open or open window position.

    Closing a Door with the Power Sliding Door Switch or the Transmitter 

    To close a door electrically:

    • The Main Switch must be ON.
    • The fuel fill door must be closed (left door only).
  23. If the Power Sliding Door Switch is used, the switch sends a signal to the power sliding door control unit for that door. If the transmitter is used, the immobilizer-keyless control unit sends an open message to the power sliding door control unit for that door.
  24. The power sliding door control unit sends a signal to the release actuator to unlatch the door.
  25. The release actuator rotates the linkage on the outer handle crank which pulls the lower roller latch cable. The lower roller latch cable releases the lower roller latch which mechanically unlatches the door.
  26. The power sliding door control unit then activates the electromagnetic clutch and starts the slide motor. The slide motor moves the cables that move the door.
  27. The power slide door motor pulser senses the movement of the slide motor, and sends pulses to the power sliding door control unit. The control unit uses these pulses to judge the speed and position of the door.
  28. When the power sliding door nears closed, the slide motor pulls the door in enough to latch the rear door latch in the half-latch position. This closes the half latch switch and the ratchet switch.
  29. The ratchet switch sends a signal to the sliding door control unit and the control unit starts the closer motor operation to pull the door in to the full latch position.
  30. The closer motor rotates the closer motor linkage on the closer unit, closing the base position switch, and finally closing the full-latch switch once the door is fully closed.
  31. When the full latch switch signal and the ratchet switch signal are received, then the power slide door control unit recognizes the full latch. Then the sliding door control unit output to the slide motor and the electromagnetic clutch are turned off. The closer motor's direction of rotation is reversed until the base switch opens again which indicates the closer motor start position, once the start position is reached, the closer motor is turned off.

    Closing a Door with the Inside or Outside Handle 

    To close a door electrically:

    • The Main Switch must be ON.
    • The fuel fill door must be closed (left door only).
  32. The inside door handle is mechanically linked to the remote control assembly. The outside door handle is linked via the outer door handle cable and outer handle crank.
    • Inner handle pulled toward closed-The inner handle rotates the linkage on the remote control assembly which pulls the inner handle lower roller latch release linkage. This rotates the linkage on the outer handle crank which pulls the lower roller latch cable. The lower roller latch cable releases the lower roller latch which mechanically unlatches the door.
    • Outer handle-The outer handle pulls the outer handle cable which rotates the outer handle crank. The outer handle crank rotates the linkage on the remote control assembly.
  33. Remote control switch 1, or 2 is closed by the rotated linkage on the remote control assembly.
    • Inner handle pulled toward closed-The linkage on the remote control assembly closes remote control switch 2, signaling the power slide door control unit to close the door.
    • Outer handle-The linkage on the remote control assembly closes remote control switch 1, signaling the power slide door control unit to close the door.
  34. From this point the door closing operation is the same as steps  15 thru  22 in the previous description.

    Opening or Closing a Door Without Power 

    The power sliding door operation is disabled if the main switch is OFF, or if there is a problem with the door that has turned on the sliding door indicator. In such cases, the door can be opened and closed by moving it manually, though some features continue to operate:

    CAUTION: The power sliding door automatically closes when halfway latched. Be careful not to pinch your fingers during this process or serious injury may occur. Make sure to disconnect the battery or remove the fuse before doing any repair or adjustments.
    • Auto Closer-While operating in the manual mode, if the door is closed to the half-latch position, the half-latch switch and ratchet switch will close signaling the power sliding door control unit to activate the closer motor in order to complete the latching sequence.
    • Unintentional Slide Prevention (USP), Manual Mode-If the main switch is turned OFF while the door is neither fully open nor fully closed, the power sliding door control unit will monitor the power slide door motor pulser for four seconds after the electromagnetic clutch is turned OFF. If the door begins to move rapidly within that time period, the power sliding door control unit will reengage the electromagnetic clutch and turn on the power slide door buzzer. This feature prevents the door from sliding open or closed unintentionally if the main switch is turned OFF while parked on a hill. The USP feature will time out after 30 minutes unless the main switch is turned back on or the inner or outer handle is operated.

    Trap Detection Operation 

    Trap Detection is the feature that detects an obstacle in the door's path as it opens or closes. This detection is disabled when the door is closing and reaches the half-latch position. The trap detection system has three detection modes:

    Door speed detection -

    • The power sliding door control unit monitors the pulses from the power slide door motor pulser as the door moves.
    • If, from these pulses, the control unit detects that the door has slowed down, the control unit reverses the slide motor.
    • The slide door buzzer sounds three times.
    • The control unit reverses the slide motor's direction, and moves the door to its previous position (open or closed). However, while closing, if the shift lever is not in P while operating the door with the foot brake applied, the door will stop and will not return to its previous position.

    Slide door motor current detection -

    • The power sliding door control unit monitors the current being used by the power slide door motor as the door moves.
    • If the current increases by more than a certain amount for the situation, which was detected as the door begins to move (such as on a hill), the control unit reverses the slide motor.
    • The slide door buzzer sounds three times.
    • The control unit reverses the slide motor's direction, and moves the door to its previous position (open or closed). However, while closing, if the shift lever is not in P while operating the door with the foot brake or parking brake applied, the door will stop and will not return to its previous position.

    Touch sensor detection -

    • The power sliding doors each have a touch sensor along the leading edge of the door.
    • The power sliding door monitors the touch sensor only when the door is closing.
    • If the touch sensor closes (resistance drops from the normal 1000 Ω level to less than 120 Ω) the sliding door control unit stops the slide motor.
    • The slide door buzzer sounds three times.
    • The control unit reverses the slide motor's direction, and moves the door to its previous position (open or closed). However, while closing, if the shift lever is not in P while the door is closing and the foot brake or the parking brake is not applied, the door stops and does not return to its previous position.

    Emergency Stop Operation 

    The Emergency Stop feature allows the operator to stop the door for any reason when it is opening or closing. It can be activated at any time using any of the following:

    • The power sliding door switch (OPEN or CLOSE) on the dashboard
    • The transmitter (button for the door that is to be stopped)
    • B-pillar power sliding door switch
    • The inner door handle
    • The outer door handle

    Turning the Main switch OFF also stops door movement (see Unintentional Slide Prevention (USP) Manual Mode).

    If, while the door is moving, the power sliding door control unit receives an open or close signal from any of the switches above, it immediately stops the slide motor. The sliding door beeper sounds three times (if the Main switch was not used to stop door movement). Depending on which operation is used to resume door operation the door will operate differently.

    • If the transmitter is used to move the door after it has stopped, the door will move in the opposite direction.
    • If the Power Sliding Door Switch or the inner handle is used, the door will move in the direction selected.
    • If the outer handle is used, the door will move toward the open position.

    Unintentional Slide Prevention (USP), Power Mode-If the emergency stop operation is activated while the door is neither fully open nor fully closed, the power sliding door control unit will keep the electromagnetic clutch activated for up to 30 minutes depending on whether or not the engine is running in order to preserve the battery. Once the electromagnetic clutch is turned off the control unit monitors the power slide motor pulser for four seconds for rapid movement of the door. If rapid movement is detected, the power sliding door control unit reengages the electromagnetic clutch and then slide motor to move the door back to its original position, and the power slide door beeper sounds a continuous tone. The power sliding door control unit then releases the electromagnetic clutch and monitors the power door motor pulser again. If the door begins to move, it repeats this operation one more time. If after disengaging the electromagnetic clutch a third time the sliding door still moves, the power sliding door control unit will reengage the electromagnetic clutch and the slide motor, and move the door to the fully open or closed position, depending on which direction the door was moving when the clutch was disengaged, then the power sliding door buzzer is turned OFF.

    Fuel Fill Door Operation 

  35. When the fuel fill door is opened, the fuel fill door switch closes and sends a signal to the left power sliding door control unit.

    The power sliding door control unit will not open the door while the fuel fill door is open. When the fuel door is opened, slide door operation is disabled. If the slide door is halfway open when the fuel door is opened then the slide door will enter the unintentional slide prevention function. Unintentional slide prevention is then active (see unintentional slide prevention (USP), Power Model), This prevents damage to the power sliding door or the fuel fill door caused by opening the sliding door while the fuel fill door is open.
