Abstract
A method for operating a power sliding door and a power liftgate in an automobile, such as a minivan, using a remote keyless entry (RKE) is comprised in a control system that includes a user input interface for receiving sliding door actuation requests from a user. The actuation signals are carried to a body control module (BCM) where the request is broadcast to a power sliding door module (PSDM) over a serial data bus communications network meeting the SAE J1850 multiplex communications protocol standard. Upon receipt of the actuation message the PSDM monitors several operating conditions of the automobile and makes a determination whether or not to carry out the power sliding door activation request. Power sliding door actuation is controlled by the PSDM via electric motors located at or near the power doors. A power liftgate module (PLGM) controls the power liftgate actuation upon via electric motors located at or near the liftgate. The user input interface includes interior switches as well as a RKE system.
