The retained power operation is canceled when the front LH or front RH door is opened.
Retained power operation period can be changed by CONSULT-III. Scan Tool Testing and Procedures .

ANTI-PINCH SYSTEM

When main power window and door lock/unlock switch detects interruption during the following close operations
