Is Your Enclave Showing These Symptoms?

• ✔ Unpredictable power door locks or windows that don’t respond.
• ✔ Interior or exterior lights flickering, staying on, or not working at all.
• ✔ The security system acting erratically or preventing the vehicle from starting.
• ✔ A persistent parasitic battery drain that leaves you with a dead battery.
• ✔ Instrument cluster gauges behaving strangely or warning lights appearing for no reason.
• ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
• ✔ Remote key fob not working correctly.

A Straightforward Guide to Your BCM Installation

Replacing the BCM in your Enclave is a manageable job for a confident DIYer. The BCM is typically located on the left-hand (driver’s) side of the dash. Follow these steps for a smooth installation.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to power down completely.
2. Access the Module: You will likely need to remove the lower dash panel beneath the steering column to gain access to the BCM. It’s usually mounted to a bracket with several large electrical connectors.
3. Disconnect and Remove: Carefully disconnect all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
4. Install the New BCM: Mount your new, pre-programmed BCM onto the bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test your lights, locks, windows, and other body functions to ensure they are working properly.
6. Perform Relearn Procedures: As noted below, you may need a professional scan tool for certain post-installation steps, like syncing the airbag system if the warning light is on.

Important Post-Installation Information

While this module comes programmed for your VIN, some vehicle systems may require a ‘handshake’ to recognize the new BCM. Please be aware of the following potential requirements:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function correctly.
• No Core Charge: You can keep your old part; there is no core charge or need to return the original module.

Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.
