Restore Control Over Your Vehicle’s Electronics
If you’re dealing with bizarre electrical gremlins in your 2012-2014 Cadillac Escalade or other GM truck/SUV, a failing Body Control Module (BCM) is often the culprit.

From the Diagnostic Bay: The Ghost in the Machine
I remember a 2013 Sierra 2500 that came into my shop with a classic “ghost” problem. The owner was frustrated, having already replaced the battery and alternator trying to solve an intermittent no-start and flickering interior lights. The battery would drain overnight for no apparent reason. After hooking up my diagnostic scanner, I saw no communication codes with the BCM (a common U0140). By monitoring the vehicle’s amperage draw with everything off, I could see a significant parasitic drain that would suddenly disappear when I wiggled the main BCM connector. The internal circuits of the original BCM were failing, keeping other modules awake and draining the battery. Installing a pre-programmed BCM like this one solved every single issue instantly. It’s a perfect example of how one part can be the root of many seemingly unrelated problems.
Is Your GM Truck or SUV Showing These Signs?
- ✔ Erratic power window or door lock operation
- ✔ Interior or exterior lights flickering, staying on, or not working at all
- ✔ The security system light flashing incorrectly or preventing startup
- ✔ Random warning messages on the dash like “Service StabiliTrak” or “Service Airbag”
- ✔ Horn honking randomly or not working when pressed
- ✔ Communication Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or U0164
A Straightforward Guide to Your BCM Installation
Replacing the BCM is a manageable job for a confident DIYer. It’s located under the driver’s side dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 15 minutes to allow all systems to power down completely.
- Access the Module: You will likely need to remove the lower dash panel or knee bolster below the steering wheel to gain clear access to the BCM.
- Disconnect the Connectors: The BCM has several large multi-pin electrical connectors. Each has a locking lever or tab. Carefully release the lever (often by pressing a tab and swinging the lever over) to unplug each connector. Do not force them.
- Remove the Old BCM: The module is typically held in place by a few bolts or plastic clips. Remove the fasteners and carefully slide the old BCM out of its bracket.
- Install the New BCM: Slide your new, pre-programmed BCM into the mounting bracket and secure it with the original fasteners.
- Reconnect Everything: Firmly plug in all electrical connectors. You should feel or hear a click as the locking levers engage. Reinstall the dash panel.
- Final Steps: Reconnect the negative battery terminal. Start the vehicle and test all functions (lights, windows, locks, etc.). Be aware of the potential post-installation procedures noted below.
Post-Installation Requirements & Core Policy
This part is sold with no core charge, so you can keep your original module. While our programming handles the majority of the setup, some vehicles may require additional steps after installation:
- 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 some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN during or after checkout, and it will arrive ready for installation, loaded with the latest GM software for your specific vehicle.
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It manages non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, and even the horn.
Where is the BCM located on my 2013 Silverado?
On most compatible GM trucks and SUVs from this era, including the 2013 Silverado and 2012-2014 Escalade, the BCM is found under the driver’s side dashboard, typically mounted to the left of the steering column.
What if my airbag light turns on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade diagnostic tool.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty BCM back to us, which saves you time and money on return shipping.
