Is Your 2010 Escalade Plagued by Electrical Gremlins?
If your 2010 Cadillac Escalade is experiencing strange and unpredictable electrical issues, a failing Body Control Module (BCM) is often the culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from power windows and door locks to interior lighting, security systems, and climate controls. When it begins to fail, it can create a cascade of frustrating problems that are difficult to diagnose.
From the Diagnostic Bay
We once had a 2010 Escalade in the shop with a complaint that was driving the owner crazy: the battery would be dead every few mornings. We tested the battery and alternator, which were both fine. After hours of tracing circuits, we discovered the BCM was intermittently failing to put all the vehicle’s systems to sleep after the key was off. It was causing a parasitic drain that was just enough to kill the battery over a day or two. Replacing the BCM with a correctly programmed unit solved the problem instantly, saving the customer from further headaches and the cost of replacing a perfectly good battery.
Common Symptoms of a Failing BCM
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s time to consider a replacement:
- ✔ Power windows or door locks operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or keyless entry malfunctioning.
- ✔ The dashboard displaying incorrect information or warning lights.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Climate control functions not responding correctly.

Don’t let a faulty module keep your luxury SUV off the road. This Body Control Module is a direct-fit replacement for your 2010 Escalade, designed to restore full functionality to your vehicle’s electronics. The best part? We handle the complex programming for you. Simply provide us with your vehicle’s VIN during checkout, and we will flash the module with the latest official GM software specific to your Escalade’s factory options. This means no expensive trips to the dealership for programming—it arrives at your door ready for installation.
Installation and Post-Install Procedures
While installation is a direct swap of the old module, some vehicles may require additional electronic ‘handshake’ procedures after the new BCM is connected. These may include:
- 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-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before shipping it to you. It arrives ready to be installed, saving you time and the high cost of dealership programming.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information to perform the programming.
What if my airbag light comes on after installation?
This is a normal possibility. It means the new BCM needs to be electronically synced with your vehicle’s airbag module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is there a core charge for my old module?
No, there is no core charge. You can keep your original module without needing to send it back.
How do I know if this part will fit my vehicle?
This BCM fits the 2010 Escalade and many other GM vehicles listed in the description. The best way to ensure a perfect match is to compare the part number on your original BCM to the numbers listed in our compatibility chart.
