Is Your GM Vehicle Plagued by Bizarre Electrical Issues?
If you’re experiencing frustrating and unpredictable electrical problems in your 2011 GMC Terrain, Chevrolet Equinox, Buick LaCrosse, or other compatible GM model, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from power windows and locks to the interior lights and security system. When it fails, it can create a cascade of confusing and seemingly unrelated symptoms that can be difficult to diagnose.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Dashboard lights flickering, warning lights staying on, or gauges behaving erratically.
- ✔ The security system light flashing, preventing the engine from starting.
- ✔ Interior or exterior lights not working correctly (staying on or not turning on).
- ✔ Unexplained battery drain that kills the battery overnight.
- ✔ Key fob not working to lock or unlock the doors.
- ✔ Communication errors when trying to read codes with a diagnostic scan tool.

Post-Installation Procedures
While this is a plug-and-play module, certain vehicle systems may require a simple relearn procedure after installation. These do not always occur but are important to be aware of.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light operation and stability control function.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What data is transferred from my old BCM?
We transfer all the vehicle-specific data required for it to function correctly, including the VIN, security information for your keys, mileage, and any specific RPO codes for your vehicle’s options. This makes it a true plug-and-play part.
Why do I need to send you my original BCM?
Your original BCM holds the unique electronic identity of your vehicle. By sending it to us, you allow us to extract this data and load it onto the replacement module. This process eliminates the need for expensive and complicated programming at a dealership.
Will I need to get my keys reprogrammed?
No. Because we clone the security data from your original module, the replacement BCM will recognize your existing keys. You will not need to perform any key relearn procedures.
How long does the whole process take?
Once we receive your original module, our service time is typically 1-2 business days. The total time will depend on shipping times to and from our facility. We will provide you with a return tracking number as soon as it ships.
What if the airbag light comes on after installation?
This is an occasional occurrence. It means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A qualified technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
