3. CHECK JAM PROTECTION FUNCTION
HINT:
S The power back door drive unit detects changes in the operating speed of the back door while the pow-
er 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 the
direction of movement will be reversed.
S 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.
S 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 your hand. Also pay thorough attention
that nothing gets caught by accident during 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),
(4) and (5) respectively.
(3) While the back door is closing, press the touch sen-
sor using the handle of a hammer or the equivalent,
as shown in the illustration.
HINT:
Skip step (4) and go to step (5).

4. CHECK WARNING BUZZER
(a) Check the warning buzzer sounding function that notifies that the power back door is open or is open-
ing 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 switches.
(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.
(b) Check that the warning buzzer that notifies the start of opening of the power back door sounds at 2
cycles of 0.5 seconds when the power back door is activated to open.
HINT:
At the start of opening of the power back door, the wireless door lock buzzer (built into the engine room) also
sounds.
5. DOOR LOCK
(a) When the battery is reconnected:
The back door is locked and cannot be opened. Therefore, it is necessary to unlock the back door using
the door control switch or transmitter switch.
6. RESET
(a) When the back door w/ motor lock is replaced:
The ECU cannot receive a switch signal from the lock. This may cause the power back door system
to enter fail-safe mode and DTC B2215 to set and also may make the system disabled.
When the lock is replaced, be sure to perform the following: first properly connect the lock, second clear
the DTC using the hand-held tester and finally recheck that no DTC is output.
(b) 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 closed based on this memory.
The power back door cannot operate without this memory. In the case where the battery has been
removed, manually close the back door fully to reset the power back door system. However, if the bat-
tery is removed/installed when the back door is fully open, the power back door operates normally, thus
the resetting the system is unnecessary.
Replacing drive unit will also cause the memory of the door positions to be last. Therefore, in such a
case resetting the system is necessary.
Reset the power back door system as follows:
(1) Fully close the power back door if opened.
(2) Check that the back door fully open and fully close.
S Unlock the power back door using the transmitter switch or the door control switch.
S Turn the ignition switch to the "OFF" position.
S Check that the power back door main switch is in the "ON" position.
S Check that the back door fully open and fully close by pushing the power back door satellite
switch or PBD button briefly.
HINT:
The jam protection function is enabled through the above initialization procedure.
