Circuit/System Description
When the ignition is turned ON, the object alarm module performs a self test to verify if any critical malfunction exists within the system. When the object alarm system has completed the power-up mode, the object alarm module establishes communication with the body control module (BCM). During the power-up mode the object detection module checks for a valid calibration data set, if no valid calibration set is found, the object alarm module disables the system and commands the red indicator ON.
