Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2010 Cadillac Escalade? Intermittent power windows, flickering lights, a security system that acts up, or even a no-start condition can often be traced back to a single component: the Body Control Module (BCM). Think of the BCM as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating and seemingly unrelated problems. In my 20+ years of diagnostics, I’ve seen how a faulty BCM can make a perfectly good vehicle feel unreliable. This isn’t just an inconvenience; it can be a safety issue.
We offer a straightforward, reliable solution. This is a replacement Body Control Module, part number 15819552, that arrives at your door ready to install. Through our professional Cloning Service, we transfer the critical data from your original module to this replacement unit and then flash it with the latest GM software updates using your VIN. This process ensures that all your vehicle’s specific options and security settings are preserved, eliminating the need for an expensive trip to the dealership for programming. It’s the most effective way to get your truck, van, or car back to 100% functionality.
Case Study: A Tricky Diagnosis
A customer brought in their 2010 Yukon XL last month with a list of strange symptoms. The radio would turn on and off by itself, the driver’s side power window wouldn’t work, and the alarm would randomly go off. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I found several communication error codes, including a U0140 (Lost Communication With Body Control Module). This pointed directly to a failing BCM. Instead of a costly dealer part and programming fee, we used our cloning service on a replacement module. After a 30-minute install and a quick Brake Pedal Position Relearn, all the phantom electrical issues were gone. The customer was thrilled to have their reliable family vehicle back without the dealership hassle.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Instrument panel gauges behaving strangely or warning lights appearing for no reason.
- ✔ The vehicle failing to start, even with a good battery and starter.
- ✔ Common Diagnostic Trouble Codes (DTCs) like U0140, U0155, B1001, or other B-series and U-series codes.
A Straightforward Guide to Your BCM Installation
For the 2010 Escalade, the BCM is typically located under the driver’s side dashboard, near the steering column. While the process is direct, always prioritize safety.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work. Wait a few minutes for the system capacitors to discharge.
- Access the Module: You may need to remove a lower dash panel or knee bolster to gain clear access to the BCM. It’s usually held in place by a few small bolts or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors. These connectors have locking tabs that must be depressed to be removed. Never pull on the wires themselves. Once disconnected, remove the old BCM.
- Install the New Module: Seat the new, programmed module in the mounting bracket and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- Post-Installation Checks: Reconnect the battery terminal. Start the vehicle and test all body functions—lights, windows, locks, etc. Note that some vehicles may require additional steps as outlined below.
- 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: Some models may require this relearn procedure to ensure proper brake light and traction control operation. This also typically requires a diagnostic scan tool.

Frequently Asked Questions
How does the Cloning Service work?
After you purchase, you will send us your original BCM. We extract the unique data, transfer it to the replacement module, and flash it with the latest GM software for your VIN. We then ship both your original module and the ready-to-install replacement back to you.
Do I need to get this programmed at the dealer?
No. Our cloning and programming service means this module is delivered to you ready for installation. This saves you the time, cost, and hassle of a dealership visit.
Is this a difficult part to install myself?
For someone with basic mechanical skills, it’s a manageable job. It involves removing a dash panel and unplugging connectors. However, be aware that post-installation relearn procedures for the airbag or brake systems may require a professional scan tool.
Will this fix my power window and door lock problems?
In most cases, yes. The BCM directly controls these functions, and if it has failed, replacing it with this programmed unit is the correct and reliable repair.
What happens to my old BCM?
Our policy is to always return your original module along with the programmed replacement unit. We do not keep your original part.
What if my airbag light comes on after I install it?
This indicates the new BCM needs to be electronically synced with the vehicle’s airbag computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a professional mechanic with an appropriate diagnostic tool.
