Removal
NOTE: Removal steps in this procedure may contain installation details.
1. WARNING: Before beginning any service procedure, refer to Safety Warnings in General Information. Failure to follow this instruction may result in serious
personal injury. See: Vehicle > Initial Inspection and Diagnostic Overview
Refer to: Health and Safety Precautions See: Vehicle > Technician Safety Information > Health and Safety Precautions (100-00 General Information,
Description and Operation). See: Vehicle > Initial Inspection and Diagnostic Overview
2. NOTE: If installing a new BCM (body control module), verify at least 2 of the vehicle keys are available prior to carrying out this procedure.
NOTE: If installing a new module, it is necessary to upload the module configuration information to the scan tool prior to removing the module. This
information must be downloaded into the new module after installation.
Upload the module configuration information from the BCM (body control module) into the scan tool by following the scan tool on screen instructions. For
additional information,
Refer to: Module Configuration - System Operation and Component Description See: Information Bus > Components > Module Configuration - System
Operation and Component Description (418-01 Module Configuration, Description and Operation).
3. Remove the 2 instrument panel insulator retainers and the instrument panel insulator.

Installation
1. NOTE: The BCM (body control module) still communicates with the scan tool with the ignition off. Use the previous scan tool session or start a new scan
tool session using the PCM (powertrain control module) part number or tear tag number located on the PCM (powertrain control module). The tear tag can be
found by double-clicking the VIN (vehicle identification number) in the top left corner of PTS after OASIS (on-line automotive service information system) has
been run for the VIN (vehicle identification number).
NOTE: Low vehicle battery state of charge can affect proper module programming. Battery state of charge can be monitored on the scan tool. A red battery

icon would indicate low vehicle battery state of charge. Over voltage may also affect module programming.
NOTE: Make sure the battery is fully charged before starting the installation procedure. Do not have a battery charger connected to the vehicle charging
system during the installation procedure.
NOTE: Carry out Steps 2-15 only if installing a new BCM (body control module).
To install, reverse the removal procedure.
2. Using the previous diagnostic scan tool session, carry out the PMI (programmable module installation) procedure for the BCM (body control module).
3. For vehicles without Intelligent Access (IA), remove the key from the ignition until Step 5. For vehicles with IA, turn the ignition OFF and leave ignition OFF
until Step 5.
4. Using the scan tool, select Tool Box/Module Programming/Programmable Parameters/Car Configuration Parameter(s).
5. NOTE: If a diagnostic scan tool is connected to the internet, it will automatically obtain As-Built data. If a diagnostic scan tool is not connected to the

internet, obtain the As-Built data from Professional Technician Society (PTS) OASIS (on-line automotive service information system). Download the As-Built
data to the scan tool or other storage device, such as a flash drive, following the on-screen instructions.
From the Car Configuration screen select " Retrieve PTS derived ASBUILT data". Follow the on-screen instructions to install the as-built data into the BCM
(body control module).
6. NOTE: Any scan tool prompts to turn the ignition on and off should be ignored during the Car Configuration Parameter process.
Do not interrupt the process until it is completed.

7. Perform the Configurable Engine Immobilizer (CEI) Lock Configuration. On the scan tool, select Body/Service Functions/CEI Lock Configuration.
8. NOTE: Due to Intelligent Access (IA), key transponder internal location, proper key orientation is required for successful key programming. Transponder
location is on right side of the steering column.
Turn ignition on. On vehicles with IA, place the IA key near the PATS (passive anti-theft system) transceiver slot.

9. Disable Factory Mode.
Refer to: Transport and Factory Mode Deactivation See: Body Control Systems > Procedures > Transport and Factory Mode Deactivation (419-10
Multifunction Electronic Modules, General Procedures).
10. NOTE: If a tear tag or PCM (powertrain control module) part number was used to establish the scan tool session, it may be necessary to now establish a
new session using the normal process.
Using a scan tool, enter the PATS (passive anti-theft system) Functions and follow the on-screen instructions to enter PATS (passive anti-theft system)
security access.
11. Select parameter reset BCM (body control module) and RFA (remote function actuator) module. Follow the on-screen instructions.
12. NOTE: PATS (passive anti-theft system) security access may need to be granted again.
Select parameter reset BCM (body control module) and PCM (powertrain control module). Follow the on-screen instructions.
