An Expert’s Note: As a technician, I’ve seen countless owners of these tough GM trucks get stuck between a rock and a hard place. The vehicle runs great mechanically, but a faulty BCM makes it nearly unusable. In the past, the only option was to tow it to a dealer, pay for diagnostics, and then pay hundreds for a new module and programming. A pre-programmed module like this changes the game. It empowers DIY-savvy owners and independent shops to perform a critical repair efficiently and affordably, keeping these dependable trucks and vans on the road where they belong.
Important Post-Installation Information
While this module is programmed for your vehicle, certain systems may require a simple recalibration procedure after installation to ensure everything is synchronized. This is a normal part of the process for many modern vehicle electronics.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool to sync the systems and turn off the light.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control functionality.
Please consult a factory service manual or a qualified technician if you are unsure about these procedures. Getting your 2003-2007 GM BCM 15747545 installed correctly ensures a lasting repair.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, wipers, the instrument cluster, and the security system. When it fails, these systems can behave erratically or stop working altogether.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is specific to your exact vehicle.
Is this part difficult to install?
For someone with moderate DIY mechanical skill, the physical installation is straightforward. The BCM is typically located under the steering column on trucks or in the center dash area on vans. The main challenge with BCM replacement is typically the programming, which we handle for you before shipping. You may need a professional scan tool for post-installation relearn procedures.
Will this fix my specific electrical problem?
This module is the definitive solution for failures within the BCM itself. While it resolves the most common electrical issues found in these vehicles, we always recommend proper diagnostics to confirm the BCM is the source of your problem before ordering. The 2003-2007 GM BCM 15747545 is designed to fix issues originating from the module.
What if the airbag light comes on after I install it?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the vehicle’s airbag computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ can be performed by any professional shop with a high-level diagnostic tool to resolve this.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your original part, which saves you the time and expense of return shipping.
