System Functions
The Body Control Module (BCM) performs the following functions:
^ Remote Keyless Entry
^ Universal Theft Deterrent System
^ PASS-Key II(R)
^ Audible Warnings
^ "Fasten Seatbelt" Indicator
^ "Low Coolant" Indicator Latching
^ Retained Accessory Power (RAP)
^ Power Door Locks
^ Rear Compartment Lid Release
^ Courtesy Lamp Control
^ Illuminated Entry
^ Delayed Interior Lamps
Wake-Up/Asleep States
"Wake-ups" are signals that will turn the BCM "ON" and cause it to begin active control and/or monitoring. The BCM is "asleep" when it has stopped
control or monitoring and has become idle again. The signals that will cause the BCM to wake-up are as follows:
^ Courtesy Lamp System
^ Remote Keyless Entry System
^ Ignition "ON" (IGN 1)
^ Park Lamps
^ Headlamps
^ Door Jamb Switches
^ Rear Compartment Lid Ajar Indicator Switch
^ Key In Ignition Switch
^ Shock Sensor
After the BCM is awake and the wake-up input is removed (i.e., a door is opened, then closed) the BCM will "go to sleep" again in 10 minutes.
If the BCM sees a door ajar wake-up, and that wake-up remains active (i.e., the door remains open with ignition "OFF") for 10 minutes, the BCM will
turn courtesy lamps "OFF," if they were "ON." This is done to prevent battery drain if a door is inadvertently left open for an extended period of time.
Power Requirements
Operating current at the BCM battery terminals should not exceed 75 milliamps while the BCM is awake with ignition "OFF;" 250 milliamps is an
approximate normal value with the ignition in "RUN."
The RAP system allows operation of the Power Door Locks, convertible top and radio until a door is opened or 10 minutes has elapsed. When the BCM
is asleep, the current should not exceed 3 milliamps (w/UA6), or 2 milliamps (without UA6). The BCM goes asleep after the ignition is shut "OFF" and
10 minutes has elapsed. Operating current drawn by the IGN 1 and IGN 3 terminals of the BCM should not exceed 15 milliamps. Refer to SECTION
