Programmed GM Body Control Module 10382479 | Flashed to Your VIN

Restore Your Vehicle’s Electronic Stability and Functionality

Are you battling a storm of bizarre electrical problems in your GM vehicle? Flickering dash lights, power windows with a mind of their own, a security system that won’t cooperate, or even a car that refuses to start? As a technician with over two decades of experience, I’ve seen these frustrating symptoms hundreds of times. More often than not, the culprit is a failing Body Control Module (BCM), the central command center for your vehicle’s comfort and security features.

This isn’t just a replacement part; it’s a comprehensive solution. We take the guesswork and the expensive trip to the dealership out of the equation. When you order, simply provide us with your vehicle’s VIN. Our experts will then flash this GM Body Control Module with the latest, most stable software directly from GM, ensuring it’s perfectly matched to your vehicle’s specific configuration and options. This eliminates communication errors and restores function right out of the box.

Common Signs of a Failing BCM

A failing BCM can manifest in numerous ways, as it controls a wide array of vehicle functions. If you’re experiencing any of the following, a faulty BCM is the likely cause:

• ✔ Erratic operation of power windows, door locks, or mirrors.
• ✔ Interior or exterior lights staying on, not working, or flickering.
• ✔ The security system or keyless entry malfunctioning.
• ✔ The horn sounding unexpectedly or not working at all.
• ✔ Dashboard warning lights appearing for no reason (e.g., ABS, Airbag).
• ✔ Communication Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or B1001.
• ✔ A no-start or intermittent starting condition where the engine cranks but won’t fire up.

A Straightforward Guide to Installation

Installing your new BCM is a manageable job for a confident DIYer or any professional mechanic. Remember that while our programming handles the software, some onboard systems require a final handshake with the new module.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
2. Locate the BCM: The location varies by model. Common spots include under the driver’s side dash (near the steering column), behind the glove box, or in the center console. Your fitment details above provide a clue.
3. Remove the Old Module: Carefully unplug all electrical connectors. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the old BCM and remove it from the vehicle.
4. Install the New Module: Seat your new, pre-programmed BCM in the same location and secure it. Reconnect all electrical connectors firmly until they click into place.
5. Reconnect the Battery: Reattach the negative battery terminal.
6. Perform Relearn Procedures: This is a critical step. You will need a capable diagnostic scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the airbag light. Additionally, a Brake Pedal Position Sensor Calibration may be required to ensure proper brake light and stability control function.
