Restore Your Vehicle’s Electrical Stability and Peace of Mind
Are you battling bizarre electrical issues in your 2015 Cadillac Escalade or another compatible GM vehicle? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly prevents your car from starting are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable problems. Instead of facing a costly trip to the dealership for a new module and expensive programming, our professional cloning service offers a reliable, plug-and-play solution.
I recently had a 2015 Sierra 1500 in the bay that was driving the owner crazy. The truck would intermittently refuse to start, the radio would cut out, and the interior lights would flicker. He’d already replaced the battery and checked the alternator. After hooking up my diagnostic scanner, I saw multiple U-series communication codes, pointing to a network issue. The culprit? A faulty BCM, part number 13587704. In these GM platforms, a new BCM requires extensive programming to sync with the vehicle’s security, VIN, and other modules. By providing a cloned module, we saved the customer over $500 in dealership fees and had his truck’s electronics functioning perfectly the same day he got the part back.
How Our Simple Mail-In Cloning Service Works
Our process is designed to be as straightforward as possible, getting you back on the road without the dealership hassle. After you purchase this service, we will contact you with detailed instructions to ship your original BCM to our facility. Once we receive it, our expert technicians will transfer all the critical data—including your vehicle’s VIN, security information, and specific options—to this replacement module. We then ship the fully programmed, ready-to-install BCM back to you. This ensures a seamless, plug-and-play installation.
Common Signs of a Failing GM BCM
- ✔ Intermittent or complete no-start condition, often with a security light illuminated.
- ✔ Power windows, door locks, or mirrors behaving erratically or not working at all.
- ✔ Dashboard lights flickering, dimming, or staying on when they shouldn’t.
- ✔ Horn honking randomly or the alarm system activating without reason.
- ✔ HVAC (heating and air conditioning) controls not responding correctly.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-series codes.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On most compatible trucks and SUVs like the 2015 Escalade, the BCM is located under the driver’s side of the dashboard, near the steering column. On other models like the Corvette or ATS, it may be in the LH dash or on the firewall. A quick search for your specific model will confirm the location.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the BCM from its mounting bracket.
- ✔ Install the New Module: Mount your pre-programmed replacement BCM and securely reconnect all electrical harnesses. Ensure they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, radio, and HVAC—to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a true plug-and-play repair, some vehicle systems may require a final handshake. If your airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. Additionally, a Brake Pedal Position Relearn may be necessary on some models to ensure proper brake light and traction control operation. These are simple procedures for any qualified technician.

Frequently Asked Questions
How does the mail-in cloning service work?
After your purchase, we’ll email you a prepaid shipping label and instructions. You simply ship us your original BCM. We then copy its essential data to the new module and ship it back to you, ready for installation.
Will I need a dealership to program this 2015 Escalade BCM?
No. Our cloning service completely eliminates the need for dealer programming. The module will arrive pre-programmed and ready to install, saving you time and money.
Is there a core charge for my old BCM?
No, there is no core charge. We need your original module to perform the data transfer, but you can keep it after the service is complete if you wish.
What if my airbag light turns on after I install it?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A qualified mechanic with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Where is the BCM located on a 2015 Cadillac Escalade?
On the 2015 Escalade, the Body Control Module is typically found under the driver’s side dashboard, mounted near the steering column for easy access.
