Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you battling bizarre electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your car’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and difficult-to-diagnose issues. This pre-programmed GM Body Control Module is the definitive solution, designed to restore full functionality and get you back on the road with confidence.

Installation and Post-Install Notes
While the programming is done for you, some vehicles may require simple relearn procedures after installation. These can often be done with a capable diagnostic scan tool. Common procedures include:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the modules.
- Brake Pedal Position Relearn: This may be required to ensure your brake lights and traction control system function correctly.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific options, such as keyless entry, security system, and powertrain. This makes the installation process as simple as possible.
Is this BCM difficult to install?
The physical replacement is typically straightforward, involving disconnecting the battery and swapping the module, which is often located under the dash. Since we pre-program the unit, you avoid the most complex part of the job. However, some vehicles may require post-install relearn procedures as noted.
What happens if I don’t do the post-install relearns?
If a required relearn procedure is not performed, you may have a persistent warning light (like the airbag light) or certain systems may not function correctly. For example, not performing the brake pedal position relearn could affect brake light operation.
Will this fix my specific electrical problem?
This module will resolve issues directly caused by a faulty BCM. The symptoms listed are strong indicators of BCM failure. However, we always recommend proper vehicle diagnostics to confirm the BCM is the root cause before ordering.
Is this a new or used part?
This is a high-quality, tested, and guaranteed functional part that has been expertly programmed to your vehicle’s specifications. It is a reliable and cost-effective alternative to a new dealership part.
Do I need to send my old BCM back?
No, there is no core charge or need to return your original module. You can keep it or dispose of it.
