Restore Control and End Electrical Frustrations

Are you dealing with bizarre electrical issues in your GM vehicle? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly prevents your car from starting? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause widespread and confusing problems. This replacement Programmed GM BCM is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN with the latest GM software updates.

Is Your Vehicle Showing These Symptoms?

• ✔ Erratic or non-functional power windows, door locks, or mirrors.
• ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
• ✔ The security or anti-theft light is illuminated, causing a no-start condition.
• ✔ False warnings on the instrument cluster (e.g., ‘Service StabiliTrak’).
• ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-codes.
• ✔ Issues with the heating and A/C blower motor controls.

A Straightforward Guide to Your BCM Installation

Replacing your BCM is a manageable job for a confident DIYer or any professional mechanic. Our pre-programming service eliminates the most difficult step—the dealership visit.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
2. Locate the BCM: On most compatible vehicles, the BCM is located under the driver’s side dashboard, often to the left of the steering column or in the center dash area. Consult a service manual for the exact position on your model.
3. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
4. Install the New Module: Mount your new Programmed GM BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
5. Power Up: Reconnect the negative battery terminal. Your vehicle’s electronics will now be controlled by the new module.
6. Post-Installation Checks: Start the vehicle and verify that functions like lights, locks, and windows are working correctly. Note that some vehicles may require additional relearn procedures as detailed below.

Important Post-Installation Procedures

While this module is delivered ready for installation, some GM security and safety systems may require a quick sync-up after the new BCM is installed.

• ✔ Airbag System Sync: If your airbag warning light is on 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 certain models, a brake pedal position sensor relearn might be necessary to ensure correct brake light and traction control operation.
• ✔ No Core Charge: You are not required to return your old module. This saves you the time, hassle, and expense of a core return.

Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
