Module Information 1

Julian Date of Build: The scan tool displays the date upon which the Body Control Module (BCM) was manufactured.

Manufacture Enable Counter (MEC): The scan tool displays the actual value for the MEC in the BCM. This information is for the assembly plant only.

Module Part Number: The scan tool displays the part number assigned to the BCM that is currently in the vehicle.

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

Lighting Calibration Number: The scan tool displays the lighting configuration calibration part number in the BCM.

Lighting Suffix: The scan tool displays the lighting configuration identification number in the BCM.

Reminder Calibration Number: The scan tool displays the reminder warning calibration part number in the BCM.

Reminder Suffix: The scan tool displays the reminder warning identification number in the BCM.

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.

Data

Battery Voltage: The scan tool displays the battery system voltage.

Inadvertent Power Timer: The scan tool displays the seconds left before the BCM turns the inadvertent power relay OFF. The BCM uses this feature to protect the battery against inadvertent battery rundown caused by components that are part of the courtesy lamp circuit. The inadvertent power relay is supplied power by the BCM for 2400 seconds (approximately 40 minutes), after the ignition is turned OFF.

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.

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).

Key In Ignition: The scan tool displays the position of the ignition key in the ignition switch cylinder. The scan tool displays YES when the ignition key is fully inserted into the ignition switch cylinder. The BCM uses this data in controlling the operation of the reminder chime feature.

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

Retained Accessory Power (RAP) Relay: The scan tool displays the commanded state of the RAP relay. The scan tool displays ON when the BCM allows the RAP relay to go to ground. The BCM will allow operation of the radio and the power windows with the ignition OFF and the doors closed for up to 1198 seconds (approximately 20 minutes).
