Programmed GM Body Control Module 15299986 | VIN-Flashed for Your Vehicle

Restore Your Vehicle’s Electrical System with a Reliable, Programmed BCM

Are you chasing electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or an instrument cluster that randomly dies are all classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM starts to fail, it can cause a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it can be a safety issue. Don’t let a faulty module dictate how your car behaves. We offer a dependable, direct-fit solution with this Programmed GM Body Control Module.

The biggest hurdle in replacing a BCM has always been the expensive and time-consuming trip to the dealership for programming. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this module with the latest GM software specific to your car, truck, or SUV. It arrives at your door ready for installation, saving you hundreds of dollars and significant downtime. This is the straightforward, professional-grade fix you’ve been looking for.

Common Symptoms of a Failing BCM

If your vehicle is experiencing any of the following, a faulty BCM is the most likely culprit. Replacing it with our Programmed GM Body Control Module can resolve these issues.

• ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, etc.).
• ✔ Power windows, locks, or mirrors working intermittently or not at all.
• ✔ The vehicle’s security system or keyless entry failing.
• ✔ Instrument panel gauges or warning lights behaving erratically (e.g., airbag light, service stabilitrak).
• ✔ Communication errors (U-codes) stored in the system, such as U0140, U0155, or U0164.
• ✔ Unexplained battery drain, leading to a dead battery overnight.

Your Straightforward BCM Installation Guide

Installing your new BCM is a manageable job for a DIYer with basic tools. The location varies by model (check your fitment details below), but the general process is similar.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge before starting work.
2. Locate the BCM: On most of these vehicles, the BCM is located under the driver’s side of the dashboard, near the steering column or behind a kick panel. On vans, it’s often in the center dash area.
3. Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module. Use a trim removal tool to avoid breaking clips.
4. Disconnect and Remove: The BCM is held in by a few small bolts or clips. Unplug the electrical connectors—they have locking tabs that need to be depressed. Once disconnected, remove the old module.
5. Install the New Module: Seat the new, pre-programmed BCM in the mounting bracket and securely plug in all electrical connectors. You should hear a ‘click’ as they lock into place.
6. Reassemble and Reconnect: Reinstall any trim panels you removed. Reconnect the negative battery terminal.
7. Perform Post-Install Procedures: Start the vehicle. If you have an airbag light on or issues with brake lights/traction control, you may need to perform the relearn procedures noted below with a capable scan tool.

Important Post-Installation Notes

While this module is delivered programmed for your VIN, some vehicle systems require a final handshake after installation. Please be aware of the following:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade diagnostic tool. This is a security measure to sync the new BCM with the airbag system.
• Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and to clear any traction control or stability system warnings.
• No Core Charge: We do not require you to send your old BCM back. There is no core charge associated with this purchase.

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