Toyota Sienna Service Manual: Jam Protection Function Activates During Power Slide Door RH
Operation
DESCRIPTION
- It may be caused by ill-fitting slide door, faulty touch sensor or
faulty pulse sensor.
- The power slide door ECU activates the slide motor to open / close
the power slide door, thus
controlling the power slide door operation. For jam and foreign object
detection, the power slide door
system uses the pulse sensor built into the slide motor and the touch sensor
installed in the front side
of the slide door.
- When the touch sensor comes in contact with an object while the
slide door is closing, the resistance of
the touch sensor changes, which is monitored by the power slide door ECU. If
a change in resistance
is detected, the ECU will judge it to be a jam and foreign object detection
in the direction that the power
slide door is moving and reverse slide motor rotation. The touch sensor
operates only while the slide
door is closing. It does not operate while the slide door is opening.
- The pulse sensor detects changes in the operating speed of the
slide door while the slide door is
operating. When the sensor detects a change in the operating speed, the
pulse from the sensor also
changes, which is monitored by the power slide door ECU. If there is a pulse
change detected, the
ECU will judge it to be a jam and foreign object detection in the direction
that the power slide door is
moving and reverse slide motor rotation.
- If a jam and foreign object detection by the touch sensor and the
pulse sensor has occurred 2 or more
consecutive times and if the 2nd or most recent detection has occurred
during closing, then the power
slide door ECU will cancel automated slide door operation and switch the
slide door to manual
operation mode (not electrically controlled). In order to return the power
slide door system to normal
operation mode, perform either of the following: manually close the slide
door fully or press the satellite
switch for the power slide door or the power slide door control switch again
(reset operation).

INSPECTION PROCEDURE
1 CHECK DTC
- Check for DTC B2223. DTC B2223 indicates a pulse
sensor malfunction.
- Without code outputs, proceed to A.
- With code outputs, proceed to B.
2 VISUALLY CHECK
- Check for foreign objects on the sliding area.
3 MANUAL OPERATION
- Turn OFF* the power slide door main switch in order to
locate the area where reverse operation has been
triggered.
* OFF is a condition that orange paint on the top of the
switch does not appear.
- Move the slide door manually, and check to make sure
no obstacles are present (no extra resistance) around
the reverse operation area and that the slide door
smoothly operates.
4 READ VALUE OF INTELLIGENT TESTER
- Using the intelligent tester, check the DATA LIST for
proper functioning of power slide door touch sensor RH.
OK (Power slide door ECU RH):
5 INSPECT POWER SLIDE DOOR TOUCH SENSOR RH
- Inspect the resistance of the sensor.
Resistance
6 CHECK WIRE HARNESS (POWER SLIDE DOOR TOUCH SENSOR RH - POWER SLIDE
DOOR ECU RH)
- Disconnect the P32 sensor and the P27 ECU
connectors.
- Check the resistance between the wire harness side
connectors.
Resistance (Check for open circuit)
REPLACE POWER SLIDE DOOR ECU RH
7 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
- Select the ACTIVE TEST and then check that the power
slide door control motor and clutch RH operates.
HINT:
During the ACTIVE TEST, the intelligent tester sends a
signal to the power slide door ECU RH to drive the motor
and clutch. If the motor and clutch operates, the motor
and clutch itself and the wire harness between the motor
and clutch and the power slide door ECU are considered
to be functioning normally.
OK (Power slide door ECU RH):
8 INSPECT SLIDE DOOR CONTROL MOTOR AND CLUTCH ASSEMBLY RH
- Remove the motor and clutch.
- Connect the battery positive (+) lead to terminal 3 and
battery negative (-) terminal lead to terminal 2.
- Apply battery voltage to the terminals and check the
motor operation.
OK
- Check the resistance of the clutch terminals.
Resistance
- Reinstall the motor and clutch with the connector
connected.
- Check the pulse of the pulse sensor.
- Using an oscilloscope, check the pulse generated
when the door is manually opened and closed.
Reference
HINT:
A cycle of the pulse changes between approx. 10 to
20 msec. according to the speeds that the slide door
is moving.
NOTICE:
When disconnecting the control motor and
clutch, initialize the power slide door system
9 CHECK WIRE HARNESS (SLIDE DOOR CONTROL MOTOR AND CLUTCH - POWER SLIDE
DOOR ECU)
- Disconnect the P22 motor and clutch, the P27 and P28
ECU connectors.
- Check the resistance between the wire harness side
connectors.
Resistance (Check for open circuit)
