From the Technician’s Bench
“I’ve seen customers spend hundreds of dollars chasing electrical gremlins, replacing batteries, alternators, and switches, only to discover the BCM was the root cause all along. A failing BCM sends confusing signals, making diagnosis a nightmare for the unprepared. This pre-programmed GM Body Control Module 25826125 takes the guesswork out of the equation. It’s the most direct path to fixing these complex issues and restoring the vehicle’s reliability, just as the factory intended.”
Post-Installation Information
While this module is programmed for your vehicle, some models may require one or more of the following relearn procedures to be performed after installation using a professional-grade scan tool. Please consult a factory service manual or qualified technician for guidance.
- Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be required to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Professional installation is recommended.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this VIN to load the correct GM factory software and settings onto the BCM before it is shipped to you.
What exactly does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lighting, security systems, wipers, and more. When it fails, these systems can become erratic.
Is this a difficult part to install?
The physical replacement is typically straightforward, often located under the dash or in the center console. However, some vehicles may require post-installation relearn procedures with a scan tool. We recommend installation by a qualified mechanic if you are not comfortable with automotive electrical work.
Will this fix my ‘Service Airbag’ light?
If the BCM is the cause of the light, yes. However, after installation, the airbag system (SDM) must be synced with the new BCM using a diagnostic tool. If the light remains on after this procedure, there may be a separate issue within the airbag system itself.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
