e. Check the back door opener switch for the power back door.
1. Check that the power back door reverses operation and moves to the fully open position when the back door opener switch is pressed during closing.
3. CHECK JAM PROTECTION FUNCTION
HINT:
- The power back door drive unit detects changes in the operating speed of the back door while the power back door is moving. If a change in the operating speed is out of the normal range, it will be judged to be a jam and foreign object detection in the direction that the power back door is moving and reverse the movement.
- When the power back door touch sensor built into the both sides of the back door is compressed, it is judged to be a jam and foreign object detection in the direction that the power back door is moving and the power back door reverses the movement.
- The power back door touch sensor operates only while the back door is closing. It does not operate while the back door is opening.
a. Check the jam protection function while the power back door is closing.
CAUTION: Do not check this function using a part of your body such as a hand. Also pay thorough attention that nothing gets caught by accident in this process.
1. Fully open the back door.
2. Press the switch that operates the power back door to activate it to close, and perform steps (3) and (5), and steps (4) and (5) respectively.
3. While the back door is closing, press the touch sensor using the handle of a hammer or equivalent, as shown in the illustration.
HINT: After this step skip step (4) and go to step (5).
4. While the back door is closing, insert a tire or equivalent between the door panel and vehicle body, as shown in the illustration, in order to interrupt closing operation.
HINT: After step (2), skip step (3) and perform this step. Then, go to step (5).
5. Check that the jam protection function is immediately activated and the power back door reverses operation to the fully open position.
b. Check the jam protection function while the power back door is opening.
CAUTION: Pay thorough attention that your body, your cloth, etc. do not get involved with by accident in this process.
1. Fully close the back door.
2. Press the switch that operates the power back door to activate it to open.
3. While the back door is opening, press, by hand, the outside surface of the back door panel that is moving so that the operating speed decreases, as shown in the illustration.
CAUTION: When pressing the door panel, do not hold the ends of the door panel. Be sure to put your hands on the surface.
4. Check that the jam protection function is immediately activated and the power back door reverses operation to the fully closed position.
c. Check operation of the power back door when the jam protection function is consecutively activated.
1. Check that power back door operation is cancelled and switched to manual operation mode (not electrically controlled) when the jam protection function has been activated 2 or more consecutive times and when the 2nd or most recent activation has occurred during closing.
HINT: Refer to steps (a) and (b) for the method that activates the jam protection function.
NOTE: In order to restore the power back door system to normal operation mode, perform either of the following: manually close the back door fully or press the power back door opener/closer switch for the power back door.
4. CHECK WARNING BUZZER
a. Check the warning buzzer sounding function that notifies that the power back door is open or is opening while the vehicle is moving (when the shift lever is moved into any position except the P position).
1. While the back door is open, check that the warning buzzer sounds at a cycle of 0.3 seconds if the shift lever is moved into any position except the P position with the ignition switch ON.
2. Turn the ignition switch ON and move the shift lever into any position except the P position. Check that the warning buzzer sounds at a cycle of 0.3 seconds when the power back door system is activated to open using the transmitter switch and power back door opener/closer switch.
3. Check that the warning buzzer stops sounding when the back door is fully closed or the shift lever is moved into the P position.
4. Check that the buzzer sounds once for 0.3 seconds for notification that power back door reverses moving direction, which is caused by switch operation or activation of jam protection function during power back door operation.
HINT: The power back door system turns OFF when the shift lever is moved into any position except P while the power back door is opening. The power back door continues to close when the shift lever is moved into any position except P while the power back door is closing
b. Check that the warning buzzer and hazard lamps that notifies the start of opening/closing of the power back door.
1. Check that the warning buzzer sounds at 2 cycles of 0.5 seconds and hazard lamps flash twice when the power back door is activated to open/close.
HINT: At the start of opening/closing of the power back door, the wireless door lock buzzer (built into the engine room) also sounds.
5. RESET (INITIALIZE)
a. Reset the power back door system:
The power back door ECU records the fully open position and the fully closed position of the power back door in its memory and the power back door fully opens and fully closes based on this memory. In the case where any of the battery, fuse, power back door ECU or power back door drive unit are removed and then reinstalled, the power back door ECU loses the memory of the door positions. In such cases, resetting the system is necessary. However the back door closer system has no effect on ECU memory.
Reset the power back door system as follows:
1. Fully close the back door.
2. Activate the transmitter switch or power back door opener/closer switch to open the power back door.
3. Check that the drive unit for the power back door stops operating at a predetermined position and that the damper stay allows the back door to move to the fully open position from the position where the drive unit stops. The power back door ECU records the fully open position at this time and resetting the system has been completed.
