Restore Your Truck’s Brain and Banish Electrical Gremlins
Are you battling bizarre electrical issues in your GM truck or SUV? Flickering lights, a battery that dies overnight, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM).

Case Study: A Tricky Diagnosis
A customer brought in a 2013 Silverado 2500 with a frustrating, intermittent no-start condition. The battery was new, the starter checked out, but every few days, it was completely dead. We scanned it and found a slew of communication codes (U-codes) pointing to multiple modules. After tracing the CAN bus network, we noticed the BCM wasn’t going to ‘sleep’ properly, causing a constant parasitic draw. We replaced the original module with a pre-programmed unit like this one, and the draw vanished. The problem wasn’t the battery or the starter; it was the BCM silently draining the life out of the truck. This is a fix I’ve performed hundreds of times in my shop.
Is Your GM Truck Showing These Symptoms?
A failing BCM can cause a wide range of confusing issues. If you’re experiencing any of the following, this module is the likely solution.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ A persistent anti-theft or security light on the dash, often leading to a no-start condition.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Warning messages like “Service StabiliTrak” or “Service 4WD” appearing randomly.
- ✔ Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other communication faults.
Your Straightforward BCM Installation Guide
Replacing the 2012-2013 Suburban 2500 BCM is a manageable job for a confident DIYer. It’s typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all modules to power down completely.
- Locate the BCM: On most of these GM trucks, you’ll need to remove the lower dash panel beneath the steering wheel to gain access. It’s a black box with several large multi-pin electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. Note their orientation. Most have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, making sure they click into place.
- Reconnect and Test: Re-install the dash panel, then reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, windows, locks, radio, and wipers. Start the vehicle to ensure it runs correctly.
Important Post-Installation Notes
Because this module is pre-programmed, most vehicles will not require any further steps. However, in some cases, additional sync procedures may be needed:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
Benefit from No Core Charge! You are not required to send your old BCM back to us. This saves you time and the cost of return shipping.

Frequently Asked Questions
Do I need to do any programming after I receive this BCM?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready to install. In some rare cases, a minor relearn procedure like for the brake pedal sensor may be needed, which can often be done without special tools.
What information do you need from me?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) to program the BCM correctly. Please provide it during or after checkout.
Is this a new or used part?
This is a quality, tested replacement part that has been inspected and programmed with the latest GM software for your specific vehicle, ensuring reliable performance.
What happens if my airbag light comes on after installation?
This indicates the new BCM needs to be synced with the airbag module (SDM). A repair shop with a professional-grade diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I have to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
