DIAGNOSTICS - POWER SLIDE DOOR SYSTEM 05BZB-02
DTC B2224 POWER SLIDE DOOR PULSE SENSOR
MALFUNCTION ON REAR LEFT DOOR
CIRCUIT DESCRIPTION
S 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.
S 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).
S In order to restore the power slide door system to normal operation mode, first solve the problem indi-
cated by DTC B2224 and then manually close the slide door fully (reset operation).
