Programming Theft Deterrent System Components
Important: When replacing a body control module (BCM) with an GM Service Parts Operation (SPO) Replacement Part, set up the replacement BCM prior to the 10-minute relearn procedure or the 30-minute relearn procedure. Refer to Body Control Module (BCM) Programming/RPO Configuration in Body Control System.
Important:
• When replacing a BCM with an GM SPO Replacement Part, the module will learn the keys immediately. The existing powertrain control module (PCM) must learn the new fuel continue password when you replace the BCM.
• When replacing a PCM with a GM SPO Replacement Part, the new PCM will learn the incoming fuel enable password immediately after programming and upon receipt of a password message. A PCM which had been installed in another vehicle would have learned the fuel enable password of the other vehicle's BCM. Perform either the 10-minute relearn procedure or the 30-minute relearn procedure to learn the fuel enable password of the current vehicle's BCM.
• When performing either relearn procedure, all previously learned keys will be erased from the BCM memory.
• Additional keys may be learned. Refer to Adding Keys .
Tools Required
• Scan tool
• Techline Terminal with current Service Programing System (SPS) software
10-Minute Relearn Procedure
Use this procedure after replacing the following components:
• The passkey III (PK3) keys
• The BCM

Turn OFF the ignition and wait 5 seconds.
With a master Passkey III key, start the vehicle. The BCM has now learned the key transponder information and the PCM has now learned the fuel continue password.
Important: Perform this step ONLY on vehicles with EXPORT configured BCM's.
Turn OFF the ignition and wait 15 seconds minimum.
Important: Perform this step ONLY on vehicles with EXPORT configured BCM's.
With a second master passkey III key, start the vehicle. The BCM has now learned the second master Passkey III key transponder information
With a scan tool, clear any DTCs.
30-Minute Relearn Procedure
Use this procedure after replacing the following components:
• The passkey III (PK3) keys
• The BCM
• The PCM, see important above
Important: This procedure is not available on vehicles equipped with option code (Z49).
If replacing a BCM with an GM SPO Replacement Part, perform the procedure to setup a new BCM prior to the 30-minute relearn procedure.
With a master passkey III key, turn ON the ignition, with the engine OFF.
Observe the STARTING DISABLED DUE TO THEFT message on the drivers information center (DIC), after approximately 10 minutes the STARTING DISABLED DUE TO THEFT message on the DIC will turn off.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.

BCM Replacement
Replace the BCM only if diagnostics in this section directs you specifically to do so. Most system problems are traceable to faulty wiring, to connectors, or to components. The BCM itself is very reliable and is not likely the cause of a fault. Do not replace the BCM before performing a complete diagnosis or recurrence of the fault will likely occur. Note: Every input to the BCM is short to ground and short to battery protected. Every output from the BCM is short to ground and short to battery protected. Therefore, the BCM does not automatically need to be replaced when there is a short found in the wiring connected to it. Repair the wiring first, then check the system for any further problem.

BCM Programming
When a BCM is replaced, it must be programmed with the Vehicle Identification Number (VIN) of the vehicle that it is being installed in. The RadioTheftlock feature uses the VIN to verify that the radio has not been removed and improperly installed in another vehicle.
The programming of the BCM is accomplished by using a scan tool. The vehicles VIN is entered in the scan tool and then transmitted via a Class 2 physical message to the BCM. The BCM stores the VIN in EEPROM. The first communication between the BCM and radio re-arms the Radio Theftlock. To set up a new BCM, select SETUP NEW BCM from the BCM Special Functions menu and follow the instructions on the screen.

Body Control Module (BCM) Replacement
If the BCM is replaced, the following procedures must be performed in the subsequent order:
• BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
• Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

A new body control module (BCM) must be programmed with the proper regular production option (RPO) configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the RPO available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
• The battery is fully charged.
• The ignition switch is in the ON position.
• The data link connector (DLC) is accessible.
• All disconnected modules and devices are reconnected before programming.
To setup a new BCM, access the Vehicle Control Systems in Computer/Integrating Systems menu on the scan tool to program the BCM. Select Module Replacement/Setup and follow the instructions on the scan tool.
If the BCM fails to accept the program, perform the following steps:
• Inspect all BCM connections.
• Verify that the scan tool has the latest software version.

Body Control Module (BCM) Replacement and Reprogramming
If the BCM is replaced or requires reprogramming, the following procedures must be performed in the specified order:
BCM Setup -- Using a scan tool, go to Vehicle Control Systems » Computer/Integrating Systems » Module Setup » Body Control Module. Select Setup BCM and follow the on-screen instructions, making sure to select the proper RPOs and input the VIN correctly.
BPP Sensor Calibration--Refer to Brake Pedal Position Sensor Calibration
Program Key Fobs--Refer to Transmitter Programming
Setup SDM Part Number in BCM -- Using a scan tool, go to Vehicle Control Systems » Computer/Integrating Systems » Module Setup » Body Control Module. Select Setup SDM Part Number in BCM and follow the on-screen instructions.

Replacing the BCM is easy , There are some steps that need to be followed but still easy ! After the new BCM is installed that's when the average person gets into trouble , because they don't have the knowledge ! They replace the BCM an it won't start an other thing's won't work . Replacing a BCM is best left to the dealer or some other qualified repair shop . It needs to be programmed an then Passlock Learn procedure has to be done. You may be replacing it when it doesn't need replacing . What problem is your vehicle having ? Have you had it checked for DTC'S - diagnostic trouble codes ? An not OBD2 codes , BCM codes won't turn on the check engine (MIL) light .
The body control module (BCM) must be programmed with the proper RPO configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes the BCM will not control the features properly. Ensure that the following conditions exist in order to prepare for BCM programming:
?€¢
The battery is fully charged.

?€¢
The ignition switch is in the RUN position.

?€¢
The data link connector (DLC) is accessible.

Follow the instructions on the Techline Terminal and scan tool to program the BCM. If the BCM fails to accept the program, perform the following steps:
?€¢
Inspect all BCM connections.

?€¢
Verify that the Techline Terminal and scan tool have the latest software version.

It has to be programmed for sure if it can be used at all . Most GM vehicle do not allow used BCM'S . It will lock up with out proper vin number an anti-theft system information installed . Your best bet is call the dealer or an independent mobile technician in you area that does reprogramming . If I may ask what kind of problems were you having that makes you think the BCM needed to be replaced ? Was a Professional type scan tool used to see if the BCM was able to communicate ? Were power an grounds checked ? Fuse's etc... I see it a lot working at the dealer , not just GM vehicles either . Customer changed out module when it didn't need it.
If installing a replacement BCM, program the BCM. Refer to Body Control Module (BCM) Programming/RPO Configuration .
An you need a subscription on GM web site , GM scan tool or a J-2534 Pass-through Device programming tool .
The procedures below are designed to set-up the body control module (BCM) correctly during BCM related service. Before you start, read these procedures carefully and completely.
Important: The following procedures must be followed:

1. Programming the BCM
2. Programming Theft Deterrent System Components, if equipped with Passlock System
3. Relearn Restraints ID

If you don't understand what this guy talks about , you really need to take it to the dealer.

Control Module Diagnostics with John Anello

There is no replaceable flasher , controlled by the BCM . body control module .
Turn Signal Lamps
The FRT/TRN/HAZ/CRTSY/MIRR and REAR/TRN/HAZ fuses in the underhood fuse block supplies battery positive voltage to the body control module (BCM). When the turn signal switch is placed in either the left or right position, a signal is sent to the BCM to illuminate the desired turn signal lamps. The BCM has an internal flasher that sends an ON-OFF voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, a separate ground signal is sent to the BCM to activate and flash all turn signal lamps including both IPC turn indicators. The front and rear turn signals are grounded at G105, G350 and G340. The sound for the turn signal indicators is produced by the IPC.
You have a bad Multifunction Switch Replacement
or BCM . You would need a GM Tech.2 scan tool To check the turn signal switch input to the BCM an to check out put of BCM to turn signal blubs . If a BCM needs to be replaced the scan tool is need to program it .
You

Replacing the BCM is the easy part , find where it lives on the vehicle , disconnect the connectors plugged into it , an then remove from it's bracket ! Now comes the hard part if you do not have a J2434 programmer tool an a subscription to the GM web site to get the info you need !

This is something best left to the dealer or a mobile Tech that does this sort of thing , if you get it wrong you could make it that the vehicle won't start or run !

It's located on the passenger side A pillar. Or behind the right kick panel ! The first thing to do would be check all Modules for DTC'S ! Yes the BCM need's to be programmed when replaced !
