Programmed GM Body Control Module 15276271 | VIN Flashed for Your Vehicle

Are you chasing electrical ghosts in your GM car, truck, or SUV? One minute the power locks work, the next they don’t. The interior lights flicker, the security system acts up, or worse, the vehicle refuses to start. As a technician with over two decades of experience, I’ve seen these frustrating, intermittent problems hundreds of times. The culprit is almost always a failing Body Control Module (BCM).

The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it starts to fail due to heat cycles, cracked solder joints, or internal electronic faults, it can create a cascade of bizarre issues that are difficult to diagnose. This isn’t just an annoyance; it can affect vehicle security and safety.

This is your direct, permanent fix. We offer a reliable replacement GM Body Control Module that eliminates the biggest headache of this repair: programming. Simply provide us with your vehicle’s VIN during checkout, and our experts will program the module with the latest official GM software specific to your vehicle. It arrives at your door ready for installation, saving you a trip to the dealership and hundreds of dollars in programming fees. This is the same process we use in our own shop to get our customers back on the road quickly and confidently.

Is Your Vehicle Showing These Symptoms?

• ✔ Erratic or non-functional power windows, door locks, or mirrors.
• ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
• ✔ The security system light is on, or the alarm goes off randomly.
• ✔ Intermittent no-start condition, even with a good battery and starter.
• ✔ Instrument cluster warning lights (like the airbag light) appearing for no reason.
• ✔ Communication-related Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other ‘U’ codes stored in the system.
• ✔ Wipers behaving erratically or not parking in the correct position.

Your Straightforward BCM Installation Guide

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 of these GM models, the BCM is located under the driver’s side of the dashboard, near the steering column or behind the left kick panel. For vans, it’s often in the center dash area. A quick search for your specific model will confirm the location.
3. ✔ Swap the Module: Carefully unplug the electrical connectors from the old module. They have locking tabs, so be gentle. Unbolt or unclip the old BCM and remove it. Mount the new, pre-programmed module in its place.
4. ✔ Reconnect and Test: Securely plug all electrical connectors into your new BCM. Reconnect the negative battery terminal.
5. ✔ Post-Install Checks: Start the vehicle and test all body functions: lights, locks, windows, wipers, etc. Note that some vehicles may require additional procedures as outlined below.

Important Post-Installation Procedures

While this GM Body Control Module is designed for a simple installation, some vehicle systems may require a ‘handshake’ with the new module. This is normal. The two most common procedures are:

• ✔ 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 airbag system with the new BCM.
• ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
