Toyota Sienna Service Manual: Power Slide Door Pulse Sensor Malfunction on
Rear Right Door
DTC B2223 Power Slide Door Pulse Sensor Malfunction on
Rear Right Door
DESCRIPTION
- A pulse sensor is built into slide door RH for jam and foreign
object detection and for slide door position
detection. The jam and foreign object detection feature of the pulse sensor
monitors the operating
speed of the slide door while the power slide door is in operation. The
slide door position detection
feature of the pulse sensor monitors where the slide door is. If the slide
door position detection feature
outputs a pulse signal that is out of the normal range, the power slide door
ECU RH will set DTC
B2223.
- If DTC B2223 is set, the power slide door system will be turned
off. Thus, the slide door can be moved
freely and will be switched to manual operation mode (not electrically
controlled).
- In order to restore the power slide door system to normal
operation mode, first solve the problem
indicated by DTC B2223 and then manually close the slide door fully (reset
operation).

INSPECTION PROCEDURE
1 CHECK WIRE HARNESS (MOTOR AND CLUTCH RH - POWER SLIDE DOOR ECU RH)
![CHECK WIRE HARNESS (MOTOR AND CLUTCH RH - POWER SLIDE DOOR ECU RH)](images/books/424/88/index370.jpg)
- Disconnect the P22 motor and clutch, and P27 ECU
connectors.
- Check the resistance between the wire harness side
connectors.
Resistance (Check for open circuit)

2 INSPECT SLIDE DOOR CONTROL MOTOR AND CLUTCH ASSEMBLY RH
![INSPECT SLIDE DOOR CONTROL MOTOR AND CLUTCH ASSEMBLY RH](images/books/424/88/index372.jpg)
- 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

- 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.
REPLACE POWER SLIDE DOOR ECU RH
If a malfunction code is displayed during the DTC check,
check the circuit listed for that code in the table below.
(Proceed to the page given for that circuit.)

DESCRIPTION
When the fold seat switch is operated, a switch operation signal is sent to
the fold seat control ECU. The
ECU receives switch operation signals from each switch and activates the folding
motor, reclining motor,
