Expert Pro Tip
Before replacing your BCM, perform a thorough check of the vehicle’s main ground connections, particularly the one located near the BCM under the driver’s side dash. A loose or corroded ground can cause symptoms identical to a failed module. Ensuring your grounds are clean and tight can prevent a misdiagnosis and protect your new module from premature failure.
Common Symptoms of a Failing GM BCM

- ✔ Security system malfunctions, causing no-start or stalling conditions.
- ✔ Headlights, taillights, or interior lights behave erratically.

Installation and Post-Install Procedures
Physical installation is straightforward for anyone with basic tools. The BCM is typically located under the driver’s side dashboard, near the steering column. The process usually takes less than 15 minutes. However, be aware of two potential post-installation procedures that may be required:
- Airbag System Sync: If the airbag warning light remains on after installation, a technician will need to use a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
We make the process hassle-free with no core charge—you can keep your old part. Get your truck back to 100% with a reliable, pre-programmed BCM.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic features, such as power windows, door locks, interior and exterior lighting, wipers, the security system, and the HVAC system.
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before it ships. This makes it a true plug-and-play solution, saving you the time and expense of a dealership visit.
My airbag light is on after installing the new BCM. Is the part bad?
No, this is a common occurrence. The new BCM needs to be electronically introduced to the airbag system (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Is this part difficult to install?
The physical installation is simple for most DIYers. It’s located under the driver’s side dash and typically held in by a few clips or bolts. The entire swap usually takes less than 15 minutes.
My original part number is 15878753, will this 25844480 work?
Yes. Part number 25844480 is an OEM-approved replacement that supersedes many older part numbers, including 15878753. It is fully compatible and programmed with the latest software for your vehicle.
