Basic Operation

Opening a Door with the Power Sliding Door Switch or the Remote Transmitter

To open a door electrically
- The Main switch must be ON
- If the ignition switch is ON, the shift lever must be in Park or in Neutral with the foot brake or parking brake ON
- If the ignition switch is OFF, the shift lever must be in Park
- The door must be unlocked, and the fuel fill door must be closed (left door only)

1. 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 remote transmitter is used, the door multiplex sends an open message 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 outer handle cable B Outer handle cable 8 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
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 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.

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, the shift lever must be in Park or in Neutral with the foot brake or parking brake ON
- If the ignition switch is OFF the shift lever must be in Park
- The door must be unlocked, and the fuel fill door must be closed (left door only)

1. The inside door handle is mechanically linked to the remote control assembly The outside door handle is linked via the outer door handle cable A, outer handle crank, and outer handle cable B
- Inner handle, child safety lock OFF-The inner handle rotates the linkage on the remote control assembly, which pulls the front aid 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 A, which rotates the outer handle crank The outer handle crank assembly pulls the outer handle cable B Outer handle cable B 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
2. Remote control switch 1 or 3 is closed 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 1, signaling the power slide door control unit to open the door.
- Inner handle, child safety lock ON-The linkage on the remote control assembly is mechanically disengaged and cannot close remote control switch 1. The child safety lock linkage is engaged and closes remote control switch 3, signaling the power slide door control unit to NOT open the door and the operation is ended.
- 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.
3. The power sliding door control unit sends a signal to the release actuator to unlatch the door.
4. The release actuator rotates the linkage on the outer handle crank,'which pulls the outer handle cable B. Outer handle cable B rotates the linkage on the remote control assembly, 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.)
5. 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.
6. 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.
7. When the power sliding door control unit judges that the door is fully open, it turns off the slide motor and the electromagnetic clutch.

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

To close a door electrically:

- The Main Switch must be ON.
- The fuel fill door must be closed (left door only).

1. 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 remote transmitter is used, the door multiplex sends an open message 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 lower roller latch cable. The lower roller latch cable releases the lower roller latch, which mechanically unlatches 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 position of the door.
6. 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.
7. The half-latch 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.
8. The closer motor rotates the closer motor linkage on the rear latch assembly, which closes the base position switch and, once the door is fully closed, the full-latch switch.
9. The full-latch switch sends a signal to the sliding door control unit, which then reverses the slide motor's direction of rotation until the base switch opens again and turns off the slide motor and electromagnetic clutch.
10. When the door is fully latched, the full-latch switch sends a signal through the junction switch to the power sliding door control unit. The control unit stops the slide motor, stops the closer motor, and returns the closer motor to its start position.

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)

1. The inside door handle is mechanically linked to the remote control assembly The outside door handle is linked via the outer door handle cable A, outer handle crank, and outer handle cable B
- 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 cable 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
- Inner handle pulled toward open, child safety lock OFF-The inner handle rotates the linkage on the remote control assembly
- Inner handle pulled toward open, child safety lock ON-The inner handle rotates the linkage on the remote control assembly
- Outer handle-The outer handle pulls the outer handle cable A, which rotates the outer handle crank The outer handle crank assembly pulls the outer handle cable B. Outer handle cable B rotates the linkage on the remote control assembly

2. Remote control switch 1, 2, or 3 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
- Inner handle pulled toward open, child safety lock OFF-The linkage on the remote control assembly closes remote control switch 1 signaling the power slide door control unit to close the door.
- Inner handle pulled toward open, child safety lock ON-The linkage on the remote control assembly closes remote control switch 3 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

3. From this point, the door closing operation is the same as steps 2 thru 10 in the previous description

Opening or Closing a Door Without Power
The door power slide 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 or MID message. In those cases, the door can be opened and closed by moving it manually, though the door does continue to operate some features:

CAUTION The power sliding door automatically closes when halfway. Be careful not to pinch your fingers during this process or serious injury may.

- 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 slide 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 slide door control unit will monitor the power slide door motor pulser for two seconds after the electromagnetic clutch is turned OFF. If the door begins to move rapidly within that time period, the power slide door control unit will reengage the electromagnetic clutch and turn on the power slide door beeper. 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 slide 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 (a sudden decrease in pulse frequency), the control unit stops the slide motor.
- The slide door beeper 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 park, or is not in neutral with the foot brake or parking brake applied, the door will stop and will not return to its previous position.

Slide door motor current detection
- The power slide 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 learned as the door begins to move (such as on a hill), the control unit stops the slide motor.
- The slide door beeper 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 park, or is not in neutral 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 slide doors each have a touch sensor along the leading edge of the door.
The power slide door monitors the touch sensor only when the door is closing.
If the touch sensor closes (resistance drops from the normal 1000 Ohms, level to less than 120 Ohms) the slide door control unit stops the slide motor.
- The slide door beeper 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 park, or is not in neutral with the foot brake or parking brake applied, the door will stop and will 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 Cl0SE) on the dashboard
- The remote transmitter (button for the door that is to be stopped)
- 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 remote 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 slide 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 door motor pulser for two seconds for rapid movement of the door. If rapid movement is detected, the power slide 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 slide door control unit then releases the electromagnetic clutch and monitors the power slide 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 slide door still moves, the power slide 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 slide door beeper is turned OFF.

Fuel Fill Door Operation
The left door locks automatically when the fuel fill door is opened.

1. When the fuel fill door is opened, the fuel fill door switch closes and sends a signal to the MICU-rear junction box.
2. The MICU-rear junction box stores the current position of the left slide door lock knob and then locks the left rear sliding door.
3. The MICU-rear junction box sends a fuel fill door status message to the left slide door control unit.
4. Once the fuel fill door is closed the fuel fill switch opens. The MICU-rear junction box returns the left rear door lock to its previous position (if previously unlocked, the door will be unlocked; if previously locked, it will remain locked).

If a passenger attempts to manually unlock the left rear slide door while the fuel fill door is open, it will lock again. This automatic lock function can be overridden by pushing the lock knob to the unlock position and holding it there for several seconds. The power slide door control unit will not open the door while the fuel fill door is open. If the door is manually opened past the lower roller stopper position, and a power close operation is requested, the power slide door control unit will move the door closed to the stopper position, then beep three times and turn off the electromagnetic clutch. Unintentional slide prevention is then active (see unintentional slide prevention (USP), Power Mode). Serious damage to the power slide door or the fuel fill door may be caused by opening the sliding door while the fuel fill door is open.

SLIDING DOOR BEEPER LOGIC

This beeper alerts the driver and occupants that the sliding door system requires attention for safety reasons. There is one beeper that is shared between both slide door control units and is part of the right power slide door control unit. The left power.slide door, control unit sends a message to the right power slide door control unit to request beeper operation. The beeper operates in three,modes:

Three Beep- Beeper sounds for 500 ms is off for 250 ms three times, this tone applies during the following conditions:

- Trap detection operation
- Emergency stop operation
- Power slide door open operation is requested from the remote transmitter or power sliding door switches on the dashboard while the door is locked.
- Power slide door close operation is requested while the touch sensor is ON.
- Power slide door open operation is requested while the fuel fill door is open.
Continuous Tone-Beeper sounds a solid, continuous tone until the condition causing the warning is eliminated This tone applies during the following conditions:

- The door is neither fully open nor fully closed, the vehicle is stopped, and the shift lever Is out of Park or the shift lever is in Neutral and the foot brake or parking brake is OFF.
- The door is not fully closed and the vehicle speed (VSP) or wheel speed (VSPWHEEL) is not zero.
- Unintentional Slide Prevention is active (electromagnetic clutch is on).
- Unintentional Slide Prevention has been canceled by the inner or outer handle, but the door is still not in the fully open or fully closed position.

Continuous Beep-Beeper sounds for 500 ms and then is off for 250 ms continuously until the condition causing the warning is eliminated. This tone applies during the following conditions:

- The door is closing while the vehicle speed (VSP) or wheel speed (VSPWHEEL) is not zero.
- The door is closing while the shift lever is out of park.

RETRIEVING DIAGNOSTIC TROUBLE CODES

Power slide door DTCs can be retrieved using the HDS. Refer to B-CAN System Diagnosis Test Mode A.

CLEARING DIAGNOSTIC TROUBLE CODES

Power sliding door DTCs can be cleared by removing the No. 7 fuse from the under-dash fuse/relay box. Once the DTCs have been cleared, re-home the power sliding door.

REMOVING THE DOORS

If the power slide door control unit has lost power for any reason (battery disconnected, etc ), the doors must be re-homed before they will work properly The power sliding door control unit must relearn the door's home position so it can use the revolution sensor to keep track of the door's position when it is moving

1. Erase the sliding door DTCs by removing the No 7 fuse from the under dash fuse/relay box
2. Turn off the Main switch for the doors Make sure the ignition switch is in LOCK (0)
3. Manually, fully close the power sliding door (the control unit must see the full latch switch and the ratchet switch closed at the same time)
4. Turn the ignition switch to ON (II) Turn on the Main switch
5. Test the door operation with the power sliding door switch, the remote transmitter, and the door handles.
