Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2015 Cadillac Escalade or another compatible GM vehicle? Flickering lights, unresponsive power windows, a security system that acts up, or strange warning messages on your dash are more than just annoyances—they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating problems. Trying to diagnose these issues can feel like chasing ghosts in the machine. This is where we come in.
We offer a reliable, straightforward solution: a replacement 2015 Escalade BCM that arrives at your door ready for installation. The key is our professional cloning service. You simply send us your original BCM, and we transfer its exact data—including VIN, mileage, and security information—to this replacement module. This process ensures seamless integration with your vehicle’s existing systems, eliminating the need for expensive and time-consuming programming at a dealership. It’s the most efficient way to get your truck or SUV back to 100%.
From the Diagnostic Bay
I remember a 2015 Escalade that came into the shop with a laundry list of complaints. The owner said the radio would randomly shut off, the driver-side window wouldn’t work, and the alarm would go off for no reason. A scan tool showed a dozen communication codes (U-codes) pointing in different directions. Instead of replacing part after part, we focused on the common link: the BCM. After confirming power and grounds were good, we knew the module itself was the culprit. A cloned BCM from our inventory had the vehicle fixed in an afternoon, saving the customer hundreds in diagnostic time and dealer programming fees. It’s a textbook example of how a failing BCM can mimic multiple other problems.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely cause:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t turn on at all.
- ✔ The anti-theft or security system malfunctioning or preventing the vehicle from starting.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ Communication error codes, such as U0140, U0155, or other U-series DTCs.
- ✔ Features like remote start or keyless entry failing to operate correctly.
Your Straightforward Installation Guide
Installing your pre-programmed 2015 Escalade BCM is a manageable task for a DIY enthusiast or any professional technician. Our cloning service makes it a simple swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any work on the electrical system.
- Locate the BCM: On most compatible models like the Escalade, Tahoe, or Sierra, the BCM is located under the steering column, behind the lower dash panel. Consult a service manual for your specific vehicle’s location if unsure.
- Remove the Old Module: Carefully unplug the electrical connectors from the original BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM in the same position and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm proper operation.
Important Post-Installation Information
Because our service clones your original data, most vehicles will not require any additional steps. However, in some cases, you may need to perform a simple relearn procedure. Don’t worry, this is standard for modern vehicle electronics.
- Airbag System Sync: If the airbag warning light is illuminated 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 relearn may be necessary to ensure proper brake light and stability control function. This can also be performed with a compatible diagnostic tool.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician for specific procedures related to your vehicle.

Frequently Asked Questions
What is the cloning service and why is it necessary?
Cloning is the process of transferring your vehicle’s specific data (like the VIN, security info, and options) from your old BCM to the new one. This makes the replacement module a perfect electronic match for your vehicle, allowing you to avoid expensive dealership programming.
How does the mail-in process work?
After you place your order, we will contact you with simple instructions for shipping your original BCM to our facility. Once we receive it, we perform the cloning service and ship your new, ready-to-install module back to you, typically within 1-2 business days.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary immobilizer and key data is stored within the BCM itself, and our cloning process transfers it perfectly to the new unit.
Is this a guaranteed fix for my vehicle’s electrical problems?
This part will correct any issues directly caused by a faulty BCM. If your vehicle has other underlying problems, such as bad wiring or a failing sensor, those will need to be addressed separately. A proper diagnosis is always recommended.
What if the airbag light comes on after I install it?
This is not uncommon. It simply means 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 in a few minutes to resolve this.
