2003-2007 Sierra 2500 Body Control Module BCM 15136876

Is Your GM Truck or Van Plagued with Electrical Gremlins?

If you’re dealing with flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a no-start condition, the root cause is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a host of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. Stop chasing down individual electrical faults and address the core issue with a reliable replacement.

Common Symptoms of a Failing BCM:

• ✔ Power windows, door locks, or mirrors working intermittently or not at all.
• ✔ Interior or exterior lights staying on, flickering, or not turning on.
• ✔ The security or anti-theft system preventing the vehicle from starting.
• ✔ Inaccurate or non-functional gauges on the instrument cluster.
• ✔ The radio or climate control system behaving erratically.
• ✔ False warning lights appearing on the dashboard, such as the airbag light.

Installation and Post-Install Notes

Installation is straightforward. For most trucks like the Silverado and Sierra, the BCM is located under the steering column. For vans like the Express and Savana, it’s typically found in the center of the dash. Once installed, while the module is pre-programmed, some vehicles may require a simple relearn procedure to sync with other onboard systems.

• Airbag System Sync: If the airbag warning light is illuminated 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 some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control function.
