Is Your GM Truck or Van Plagued by Baffling Electrical Issues?
If your 2004-2007 GMC Savana, Chevrolet Express, or other GM truck is experiencing strange electrical behavior, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central nervous system for your vehicle’s comfort and security features. When it malfunctions, it can cause a cascade of frustrating problems, from flickering lights and a dead instrument cluster to a vehicle that won’t start. This VIN-programmed BCM, part number 15137393, is the direct-fit, reliable solution to restore your vehicle’s full functionality without a costly trip to the dealership.

Before you begin the installation, always disconnect the negative terminal of your vehicle’s battery. This not only prevents accidental shorts but also helps the vehicle’s various electronic systems reset and recognize the new module upon reconnection, which can resolve minor communication errors.
Common Symptoms of a Failing GM BCM
- ✔ Intermittent or non-working power windows, door locks, or interior/exterior lights.
- ✔ HVAC blower motor or climate controls operating erratically or not at all.
- ✔ The security system light is flashing, preventing the engine from starting (Passlock issues).
- ✔ An airbag warning light on the dash, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Unpredictable wiper operation or horn malfunctions.
- ✔ Communication errors with other modules, leading to a host of confusing DTCs.

Post-Installation Procedures
While our VIN programming handles the majority of the setup, some vehicles may require a simple relearn procedure after installation. If your airbag light remains on, a technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary to ensure proper brake light and traction control function. These are standard procedures when replacing a BCM and can be completed by most qualified auto repair shops.
