Restore Your Vehicle’s Electrical System
Are you battling frustrating electrical problems in your GM truck or SUV? Flickering lights, a malfunctioning security system, or an HVAC system with a mind of its own are common signs of a failing Body Control Module (BCM). This vital component acts as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing issues. This OEM-quality BCM, part number 15198116, is the definitive solution for your 2003-2006 Suburban 2500 and a wide range of other GM vehicles. It arrives pre-programmed to your vehicle’s specific VIN, ensuring a straightforward, plug-and-play installation without requiring a costly trip to the dealership.

Simply provide your VIN during checkout, and our technicians will flash the module with the latest GM software updates specific to your vehicle. This process ensures all factory-installed options are recognized and operate correctly from the moment of installation.

Installation and Post-Install Considerations
Installation is typically a quick process, often taking less than 15 minutes. The BCM is usually located under the driver’s side dashboard, near the steering column. We recommend disconnecting the battery before swapping the modules. Once installed, most functions will be immediately restored. However, please note the following:
- Airbag System Sync: If the airbag light remains on 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: In some cases, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control functionality.
- No Core Charge: You are not required to return your old module, saving you time and hassle.
This module is a direct replacement for multiple part numbers, including 15116066, 15136225, 15198116, 15257043, and more, ensuring broad compatibility across the GM lineup.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. This Body Control Module comes fully programmed to your vehicle’s VIN. It is ready for installation right out of the box, saving you time and the expense of dealership programming.
Where is the BCM located in my 2004 Silverado or 2005 Tahoe?
In most compatible trucks and SUVs like the Silverado, Sierra, Suburban, and Tahoe, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
What does ‘Setup SDM Primary Key in BCM’ mean?
This is a security procedure required on some vehicles to sync the new BCM with the existing Sensing and Diagnostic Module (SDM), which controls the airbags. It can only be performed with a professional-grade diagnostic tool if the airbag light is illuminated after installation.
Will this fix a no-start problem?
If your no-start issue is caused by the BCM’s control over the vehicle’s security or anti-theft system, then yes, replacing it can resolve the problem. However, no-start conditions can have many causes, so proper diagnosis is key.
Is this a new or used part?
This is an OEM-quality, tested part that has been inspected and programmed to meet or exceed original factory specifications, ensuring reliable performance. It is backed by our one-year warranty.
Do I have to send my old part back?
No. There is no core charge or requirement to return your original BCM. You can keep it or dispose of it at your convenience.
