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.

Data

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

Input 1

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.

Horn Relay Input: The scan tool displays the state of the horn relay. The scan tool displays ACTIVE when the BCM senses that the horn relay is being commanded ON by the relay coil circuit being grounded.

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.

Input 2

Courtesy Lamp Relay: The scan tool displays the state of the courtesy lamp relay. The scan tool displays ON when the BCM commands the courtesy lamps ON by providing a ground for the courtesy lamp relay.

Outputs

Courtesy Lamp Relay: The scan tool displays the commanded state of the courtesy lamp relay. The scan tool displays ON when the BCM allows the courtesy lamp relay coil to go to ground to activate the courtesy lamps.

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.

Horn Relay: The scan tool displays the commanded state of the horn relay. The scan tool displays ON when the BCM allows the horn relay to go to ground to activate the horn(s). The BCM will command this state when the PANIC button on the keyless entry transmitter is activated and when there is an unauthorized entry into the vehicle.

Interior Lighting Mode: The scan tool displays the name of the feature which commanded the interior lights on. The scan tool displays NONE when the interior lights are not commanded on. The scan tool displays INTERIOR, ILLUM. ENTRY, EXIT LIGHTING and REMOTE ILLUM. when the respective mode commands the interior lights on.

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.

Security Data

Content Theft Lamp: The scan tool displays the state of the SECURITY lamp. The scan tool displays ON when activated by an unauthorized entry.

Content Theft State: The scan tool displays the state of the content theft feature. The scan tool displays ON when activated by an unauthorized entry.

Door Key Switch: The scan tool displays the state of the door key switch. The scan tool displays ACTIVE when the switch is activated in either door key cylinder.

Ignition 1: The scan tool displays the state 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 state of the ignition switch. The scan tool displays ACTIVE when the ignition switch is in the RUN position.
