Restore Control Over Your Vehicle’s Electronics
Are you dealing with baffling electrical issues in your Cadillac Escalade or another GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts on its own, or random warning messages on your dash are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s comfort and convenience features, a faulty BCM can make driving a frustrating and unpredictable experience. This isn’t just an annoyance; it can be a safety concern when essential systems like lighting and door locks don’t work as they should.
We offer a reliable and straightforward solution. This is a replacement Body Control Module, part number 15921352, that comes with our expert Cloning Service. This means you get a component that is a true plug-and-play fix. We transfer the critical data from your original, failing module directly onto this replacement unit. The result? No expensive trips to the dealership for programming, no complex setup procedures. You get a part that is ready for installation right out of the box, configured specifically for your vehicle’s VIN and options.
A Technician’s Notebook: The Phantom Drain Mystery
I once had a 2010 Cadillac Escalade in my bay with a battery that would be dead every morning. The owner had already replaced the battery and alternator, but the problem persisted. Standard parasitic draw tests were inconclusive—the draw was intermittent. After hours of diagnostics, I focused on the BCM. By monitoring the data bus, I noticed the BCM was failing to put other modules to sleep, causing them to stay active and drain the battery overnight. Swapping in a cloned 2010 Escalade Body Control Module solved the issue instantly. It’s a perfect example of how a failing BCM can cause symptoms that seem completely unrelated, making it one of the trickiest components to diagnose without experience.
Common Symptoms of BCM Failure
If your vehicle is exhibiting any of these behaviors, a failing BCM is the likely culprit. This replacement module is designed to resolve these very issues and restore proper function.
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ False warning lights on the instrument cluster (e.g., “Service Theft System”).
- ✔ Communication error codes, often in the U-series (e.g., U0140, U0155), indicating a loss of communication with other modules.
- ✔ Unexplained battery drain when the vehicle is off.
Your Straightforward BCM Installation Guide
Installing your cloned BCM is a manageable job for a DIY enthusiast. The key is that the difficult programming work is already done for you. Always consult a service manual for your specific vehicle’s BCM location (often under the dash or steering column).
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: Find the original BCM in your vehicle. On the 2010 Escalade, it’s typically located under the steering column.
- Disconnect and Remove: Carefully unplug the electrical connectors. 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 location and securely reconnect all electrical harnesses. You should hear a click as they lock into place.
- Reconnect Power: Re-attach the negative battery terminal.
- Test and Verify: Start the vehicle and test all body functions—lights, windows, locks, wipers, etc.—to confirm the repair. Note the post-installation procedures below.
Important Post-Installation Steps
While our cloning service makes this a near plug-and-play process, some vehicle systems may require a relearn procedure to fully sync with the new BCM. These are standard procedures that a professional technician can perform quickly with a capable scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

What exactly is a ‘Cloning Service’?
What exactly is a ‘Cloning Service’?
Cloning is a process where we transfer the essential vehicle-specific data—like the VIN, security information, and optional feature settings—from your original BCM to the replacement unit. This makes the replacement module recognize your vehicle and keys perfectly, eliminating the need for expensive and time-consuming dealer programming.
Do I need to send you my original BCM?
Yes. For the cloning service to work, we need your original module to extract the data. After you purchase, we will provide instructions for sending it to us. We always return your original module along with the newly programmed replacement.
Will this 2010 Escalade Body Control Module fix my specific problem?
This module is designed to fix issues directly caused by a faulty BCM, such as the symptoms listed above. While it solves the vast majority of electrical gremlins, proper diagnosis is key. We recommend confirming the BCM is the source of the fault before ordering.
What happens if my airbag light comes on after installation?
This is a known possibility. The vehicle’s Sensing and Diagnostic Module (SDM) may need to be synchronized with the new BCM. A professional technician with a GM-compatible diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this and turn off the light.
Do you keep my old part?
No, we do not require your original module as a core. The customer’s original BCM is always returned to them along with the programmed replacement unit.
