Common Symptoms of a Failing BCM & Your Direct-Fit Solution
The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a wide range of confusing symptoms. If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior or exterior lights behaving erratically (staying on, not turning on, or flickering).
- The security or anti-theft system preventing the engine from starting.
- Erratic gauge cluster behavior or warning lights that won’t turn off.
- Remote keyless entry failure.

We replicate the dealer-level setup process, so you get a component that communicates flawlessly with your truck’s other modules right away. This is the correct way to replace a 2003-2007 Silverado Sierra Express Savana BCM and avoid future headaches.
Important Post-Installation Information
While this BCM is programmed for your vehicle, certain systems may require a relearn procedure after installation to sync properly. This is a normal part of the repair process.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.

Frequently Asked Questions
Do I need to take my vehicle to the dealer for programming?
No. The main benefit of our service is that we program the Body Control Module to your vehicle’s VIN before we ship it to you. This allows you to install it without requiring a trip to the dealership for programming, saving you time and money.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note to your order during checkout or reply to your order confirmation email with the information.
What if the airbag light comes on after I install the BCM?
This is a possibility and is part of the vehicle’s security system. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade diagnostic tool to resolve it.
Is this a difficult part to install myself?
For someone with moderate mechanical experience, the physical replacement is straightforward. The BCM is typically located under the steering column or in the center dash area. However, be aware that post-installation relearn procedures for the airbag or brake systems may be necessary and require a capable scan tool.
What part numbers does this BCM replace?
This module is a direct replacement for the following GM part numbers: 15198115, 15167329, 15194169, 15747545, 15136224, 15116065, 15136876, and 10367689.
