Module Information 1
Manufacture Enable Counter (MEC): The scan tool displays the
actual value for the MEC in the body control module (BCM). This information
is for the assembly plant only.
Software Design Suffix: The scan tool displays the version
of the software part number in the BCM.
Software Part Number: The scan tool displays the software identification
number (ID) in the BCM.
Module Information 2
Retained Accessory Power (RAP) Calibration Number: The scan
tool displays the RAP calibration part number in the BCM.
Retained Accessory Power (RAP) Suffix: The scan tool displays
the RAP identification number in the BCM.
Security Calibration Number: The scan tool displays the security
calibration part number in the BCM.
Security Suffix: The scan tool displays the security identification
number in the BCM
Module Information 3
Module Part Number: The scan tool displays the part number
assigned to the BCM that is currently in the vehicle.
Data
Battery Voltage: The scan tool displays the battery system
voltage.
Retained Accessory Power (RAP) Timer: The scan tool displays
the seconds left before the BCM turns the RAP relay OFF. The BCM uses this feature
to allow the operation of the radio and the power windows for up to 1198 seconds,
approximately 20 minutes, after the ignition is turned OFF. After the time has
elapsed or the door is opened the BCM will open the ground circuit for the RAP
relay.
Input 1
Door Handle Switch: The scan tool displays the position of
the door handle. The scan tool displays ACTIVE when a door handle is raised and
INACTIVE with all doors closed and the door handles at rest.
Door Lock Relay Feedback: The scan tool displays the state
of the door lock relay. The scan tool displays ON when the BCM senses the door lock
relay coil is energized.
Drivers Door Jamb Switch: The scan tool displays the position
of the drivers door. The scan tool displays ACTIVE when the drivers door is open.
Ignition 1: The scan tool displays the position of the ignition
switch. The scan tool displays ACTIVE when the ignition switch is in the RUN or
CRANK position.
Ignition 3: The scan tool displays the position of the ignition
switch. The scan tool displays ACTIVE when the ignition switch is in the RUN position
only.
Ignition Power Mode: The scan tool displays the position of
the ignition switch. The scan tool displays OFF, RUN, CRANK and UNKNOWN. The UNKNOWN
display is when the BCM can not determine the position of the ignition switch,
between the OFF and RUN positions.
Last Remote Function Actuation (RFA) Command Since Wake-Up: The scan tool displays the last RFA commanded message from the BCM. The scan tool
displays NONE when the BCM awakens from asleep status without receiving a RFA
module request from a programmed key fob. The scan tool displays LOCK, UNLOCK
or PANIC when the BCM is awake and a command is activated from the key fob to
the RFA module.
Passenger Door Unlock Input: The scan tool displays the state
of the passenger door unlock relay. The scan tool displays ACTIVE when the BCM senses
that the passenger door unlock relay is being energized.
Remote Function Actuation (RFA) Message Since Wake-Up: The scan
tool displays the last message sent to the BCM from the remote control door lock
receiver.
Retained Accessory Power (RAP) Relay Feedback: The scan tool
displays the state of the RAP relay. The scan tool displays ON when the BCM activates
the RAP relay.
Outputs
Door Lock Relay: The scan tool displays the commanded state
of the door lock relay. The scan tool displays ON when the keyless entry transmitter
LOCK button or the power lock switch is activated. The BCM allows the door lock
relay coil to go to ground, locking the doors.
Driver Door Unlock Relay: The scan tool displays the commanded
state of the driver door unlock relay. The scan tool displays ON when the keyless
entry transmitter UNLOCK button or the power unlock switch is activated. The BCM
allows the driver door unlock relay coil to go to ground, unlocking the doors.
Passenger Door Unlock Relay: The scan tool displays the commanded
state of the passenger door unlock relay. The scan tool displays ON when the BCM
allows the passenger door unlock relay to go to ground to UNLOCK the passenger
door(s). The BCM will command this state when the UNLOCK button on the keyless
entry transmitter is activated twice within 3 seconds.
