An Expert’s Note on BCM Replacement
As a technician, I’ve seen countless hours and dollars wasted trying to diagnose bizarre electrical issues on these otherwise bulletproof GM trucks. Often, the problem traces back to the BCM, which can fail from age, vibration, or moisture intrusion. In the past, the only option was a new module from the dealer, followed by a tow and an expensive programming session. A pre-programmed 2003-2007 GM Truck Body Control Module like this one is a game-changer. It puts the repair back in the hands of independent shops and capable DIYers, saving significant downtime and getting these essential work vehicles back on the job faster.
Frequently Asked Questions
What does a BCM do on a Silverado or Sierra?
The Body Control Module (BCM) acts as the central computer for your truck’s non-engine related electronic systems. It controls functions like power windows, door locks, interior and exterior lighting, the security system, and the instrument cluster gauges.
Is this BCM difficult to install?
The physical installation is typically straightforward. On most Sierra and Silverado pickups, it’s located under the steering column. On Express and Savana vans, it’s usually behind the center dash. Since we pre-program the unit, the most complex part of the job is already done for you. Basic hand tools are all that’s required for the physical swap.
Will I need to perform any procedures after installation?
In some cases, yes. If your airbag light comes on, a ‘Setup SDM Primary Key’ procedure may be needed. Additionally, a ‘Brake Pedal Position Relearn’ might be required for proper brake light and traction control function. These procedures require a professional-grade scan tool and can be performed by most automotive repair shops.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it is essential for programming the module correctly.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your original module, which saves you the cost and hassle of return shipping.
What if my original part number isn’t 15198115?
That’s okay. This BCM is a direct replacement for multiple part numbers, including 15167329, 15194169, 15747545, 15136224, 15116065, 15136876, and 10367689. As long as your vehicle is listed in the compatibility chart, this module will work for you.
