Restore Your Cadillac’s Electrical System with a Plug-and-Play Solution
Are you tired of chasing electrical gremlins in your 2010 Cadillac Escalade ESV? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a security system that acts up on its own are all classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and convenience features, a faulty BCM can make driving a frustrating and unpredictable experience. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
This is a direct-fit replacement Body Control Module, part number 15921352, that arrives at your door programmed and ready for installation. We take the guesswork and expensive dealer visits out of the equation. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest, most stable GM software specific to your Escalade. This ensures seamless integration and restores all functions to factory specifications.
Case Study: A Tricky Diagnosis
A customer’s 2010 Escalade ESV came into the shop last month with a bizarre set of symptoms: the radio would randomly shut off, the driver’s side power seat had a mind of its own, and the anti-theft light would stay on, sometimes preventing the truck from starting. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple communication error codes across different systems, all pointing back to one component: the BCM. It was failing internally, causing a data storm on the vehicle’s network. We installed one of our pre-programmed BCMs, performed the necessary key relearn and SDM setup, and all the ghost-like issues vanished. It’s a common failure I’ve seen hundreds of times on these GM platforms.
Is Your Escalade Showing These Symptoms?
A failing BCM can cause a wide range of issues that may seem unrelated. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Erratic or non-working interior/exterior lights.
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Instrument panel gauges behaving strangely or going dark.
- ✔ The security system engaging randomly or causing a no-start condition.
- ✔ Key fob not working correctly.
- ✔ HVAC (Air Conditioning and Heat) control problems.
- ✔ Communication error codes (U-codes) stored in the system.
A Straightforward Guide to Installation
Replacing the 2010 Escalade ESV BCM is a manageable job for a confident DIYer. The module is typically located under the steering column on the driver’s side. Follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the BCM: On the 2010 Escalade ESV, you’ll find the BCM mounted under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once all connectors are removed, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect the Battery: Re-attach the negative battery terminal.
- Critical Final Steps: After installation, two procedures are often required. First, perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible diagnostic tool to ensure the airbag system communicates correctly. Second, some vehicles may need a brake pedal position sensor recalibration. If you’re unsure, consulting a service manual or a professional is recommended.

Frequently Asked Questions
Do I need to do any programming myself?
No. This 2010 Escalade ESV BCM is delivered to you pre-programmed for your specific vehicle. We handle the complex flashing process before we ship. All you need to do is provide your VIN when you order.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your vehicle. We use it to access the correct GM software and vehicle options, ensuring the BCM we send you works perfectly with your specific Escalade ESV features.
Is this a difficult part to replace at home?
For someone with moderate mechanical skill, it’s a very achievable job. It primarily involves removing a dash panel and swapping the module. The most important part is following the post-installation procedures, like the airbag system reset, which may require a capable scan tool.
Will this fix my ‘Service Airbag’ light?
If the light is on due to a communication fault with a bad BCM, then yes. However, after installing the new BCM, you MUST perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light and ensure the system is functioning correctly.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function in your vehicle. We will contact you after your purchase to request the VIN if it’s not provided, which may delay your order.
