Is Your GM Truck or SUV Plagued by Bizarre Electrical Problems?
If you’re dealing with a frustrating array of electrical gremlins in your 2012-2014 GM vehicle, 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 your power windows and door locks to your interior lighting and security system. When it begins to fail, it can cause a cascade of confusing and seemingly unrelated issues that can be difficult to diagnose.
From the Diagnostic Bay
We had a 2013 Silverado 2500 come into the shop with a classic case of BCM failure. The owner was frustrated with an intermittent no-start condition, flickering dome lights, and a power window that had a mind of its own. He had already replaced the battery twice, thinking it was a power drain issue. After running network diagnostics, we found communication faults pointing directly to the BCM. A replacement, correctly programmed module like this one resolved all his issues in under an hour. It’s a common story, and the fix is often simpler than people think.
Symptoms of a Failing GM Body Control Module
A faulty BCM can manifest in many ways. If you’re experiencing several of the following symptoms, it’s a strong indication that your BCM needs replacement:
- ✔ Power windows or door locks working intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or not turning on.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Warning lights appearing on the instrument cluster for no apparent reason.
- ✔ Unexplained battery drain that kills your battery overnight.
- ✔ Radio or climate control systems behaving erratically.
- ✔ Horn honking randomly or not working when pressed.

Installation and Post-Install Procedures
After installing your pre-programmed BCM, your vehicle’s primary functions should be restored. However, in some cases, additional synchronization procedures may be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be needed. This is also performed with a capable diagnostic tool.
We also make it easy with no core charge. You can keep your old module without the hassle of shipping it back.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. This is the key benefit of our service. We program the Body Control Module to your vehicle’s specific VIN before we ship it to you. It arrives ready to be installed.
Where is the BCM located on my 2013 Silverado or Sierra?
The BCM is typically located under the driver’s side of the dashboard, near the steering column. It’s an accessible location for replacement.
What information do you need from me?
After you place your order, we will need the 17-digit Vehicle Identification Number (VIN) from your truck or SUV. This ensures we load the correct software and vehicle options into the module.
Will this fix my dead battery issue?
If the battery drain is caused by the BCM failing to let other modules go to ‘sleep’ or by keeping lights on, then yes, this will resolve the issue. Proper diagnosis is always recommended to confirm the BCM is the source of the parasitic draw.
What happens if my airbag light is on after I install it?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this compatible with part number 22737275?
Yes, this module is a direct, compatible replacement for part numbers 22846364, 22737275, and 22846365.
