Toyota Sienna Service Manual: Power Slide Door Pulse Sensor Malfunction on Rear Left Door
DTC B2224 Power Slide Door Pulse Sensor Malfunction on Rear Left Door
DESCRIPTION
- A pulse sensor is built into slide door LH 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 LH will set DTC B2224.
- If DTC B2224 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 B2224 and then manually close the slide door fully (reset operation).

WIRING DIAGRAM
INSPECTION PROCEDURE
1 CHECK WIRE HARNESS (MOTOR AND CLUTCH LH - POWER SLIDE DOOR ECU LH)
- Disconnect the P21 motor and clutch, and the P25 ECU connectors.
- Check the continuity between the wire harness side connectors.
Resistance (Check for open circuit)
2 INSPECT SLIDE DOOR CONTROL MOTOR AND CLUTCH ASSEMBLY LH
- 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.
