POWER SLIDE DOOR SYSTEM, Diagnostic DTC:B2224

DESCRIPTION

• A pulse sensor is built into the slide door LH for jam and foreign matter detection and for slide door position detection. The pulse sensor monitors the operating speed of the slide door while the power slide door is moving. The pulse sensor monitors where the slide door is. If the pulse signal is out of the normal range, the power slide door ECU LH will store DTC B2224.

• If DTC B2224 is stored, 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 repair the malfunction indicated by DTC B2224 and then manually close the slide door fully (reset operation).
