Restore Full Electrical Function to Your Vehicle
Are you experiencing bizarre and frustrating electrical problems in your 2010 Cadillac Escalade ESV? Issues like flickering lights, malfunctioning power windows, or a security system that acts up on its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of seemingly unrelated problems. This replacement Body Control Module, part number 15819552, is the definitive solution to restore your vehicle’s factory performance and reliability.
We make the repair process simple. Unlike a dealership that requires you to bring the vehicle in for expensive programming, we handle the critical software setup for you before we ship. Simply provide us with your vehicle’s VIN after your purchase, and our technicians will flash the module with the latest GM software specific to your Escalade ESV. This ensures that when the part arrives, it’s ready for installation, saving you time, money, and hassle.
From the Diagnostic Bay
We recently had a 2010 Escalade ESV in the shop with a list of strange symptoms. The owner reported that the key fob would only work intermittently, the interior dome lights would stay on after the doors were closed, and the radio would sometimes not power on. A scan showed multiple communication errors pointing towards the BCM. After confirming power and ground to the module were good, we installed one of our pre-programmed BCMs. Immediately, all the ghost-like electrical issues were gone. The key fob worked from 50 feet away, the lights operated correctly, and the infotainment system came to life. It’s a perfect example of how a single failing module can wreak havoc on a modern vehicle’s systems.
Is a Failing 2010 Escalade ESV BCM Causing Your Problems?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following issues, a failing Body Control Module is the likely culprit. This module is the correct fix for these and other electrical gremlins.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights) staying on, flickering, or not turning on.
- ✔ The vehicle’s security system engaging randomly or showing a “Service Theft System” message.
- ✔ Instrument panel gauges behaving erratically or going dark.
- ✔ Keyless entry remote (fob) not working or having a very short range.
- ✔ The horn honking unexpectedly or failing to work when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
Installation and Post-Install Notes
Installation is straightforward for those with mechanical experience. The BCM is typically located under the steering column. Once the new module is installed, some vehicles may require additional steps to ensure all systems are synchronized.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync 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 correct brake light and traction control operation.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and keyless entry. It’s the command center for passenger comfort and convenience features.
Do I need to take my vehicle to the dealer for programming?
No. We pre-program this BCM to your vehicle’s specific VIN before shipping it to you. This makes the module ready to install right out of the box, saving you a costly trip to the dealership.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it.
Is this BCM difficult to install?
For someone with moderate DIY automotive experience, the installation is manageable. The BCM is usually located under the driver’s side dashboard. However, if you are not comfortable working with vehicle electronics, we recommend professional installation.
My original part number is different. Will this still work?
Yes. This module is a direct replacement for a long list of GM part numbers that have been superseded over the years. As long as your vehicle is on the compatibility list, this module will function correctly.
What is the core charge for this part?
There is no core charge for this BCM. You can keep your old, non-working module without needing to send it back.
