DIAGNOSTICS - POWER SLIDE DOOR SYSTEM 05BZA-02
DTC B2223 POWER SLIDE DOOR PULSE SENSOR
MALFUNCTION ON REAR RIGHT DOOR
CIRCUIT DESCRIPTION
S 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.
S 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).
S In order to restore the power slide door system to normal operation mode, first solve the problem indi-
cated by DTC B2223 and then manually close the slide door fully (reset operation).
