Programmed GM Body Control Module BCM 15299986 | VIN Matched for 08-12 Models

Is Your GM Plagued by Electrical Gremlins?

As a technician with over 20 years on the floor, I’ve seen it all. A 2010 Tahoe comes in with wipers that won’t turn off, a dead radio, and power windows with a mind of their own. A 2009 Impala has a persistent security light and won’t start intermittently. The common culprit? A failing Body Control Module (BCM). This module is the central nervous system for your vehicle’s comfort and convenience features, and when it goes, it can cause a cascade of frustrating, seemingly unrelated problems.

Don’t let a faulty BCM take your vehicle off the road or drain your wallet with diagnostic fees. This is your direct, reliable solution to restore order and functionality.

The Simple, No-Hassle Solution: A VIN-Programmed BCM

Forget expensive dealership visits and the headache of finding a shop that can program a new module. We handle the critical step for you. When you purchase this GM Body Control Module, we flash it with the latest official GM software, perfectly matched to your vehicle’s specific VIN. It arrives at your door ready to be installed, saving you time, money, and stress.

Symptoms a Failing BCM Can Cause:

• ✔ Erratic or non-functional power windows, door locks, and mirrors.
• ✔ Interior or exterior lights staying on or not working at all.
• ✔ The security system acting up, causing no-start conditions.
• ✔ Wipers or climate control behaving erratically.
• ✔ False warnings on the instrument cluster.
• ✔ Communication issues with other vehicle modules (DTC U-codes).

Plug-and-Play Installation: Get Back on the Road Fast

While professional installation is always an option, this is a job many DIYers can tackle. The process is straightforward, as the programming is already done.

1. Safety First: Always disconnect the negative battery terminal and wait a few minutes before starting 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 kick panel. On vans like the Express/Savana, it’s often in the center dash.
3. Swap the Module: Carefully unplug the electrical connectors from the old BCM. Remove any retaining bolts or clips, and take out the old module. Install the new one in its place.
4. Reconnect and Test: Securely plug all connectors into your new, pre-programmed BCM. Reconnect the battery terminal and test all functions – lights, locks, windows, etc.

Important Post-Installation Steps

This is a critical step for safety and full functionality. After installing your new GM Body Control Module, certain procedures are necessary:

• Airbag System Reset: To clear the airbag warning light, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level diagnostic tool. This re-establishes communication between the airbag system and the new BCM.
• Brake Pedal Position Sensor Relearn: Some vehicles may require a brake pedal position sensor relearn or recalibration. This ensures the brake lights and stability control system function correctly.

If you are not equipped to perform these relearn procedures, we strongly recommend seeking assistance from a qualified technician.
