Is Your GM Vehicle Experiencing Strange Electrical Problems?
If your 2015 Cadillac Escalade ESV, Chevy Silverado, or GMC Sierra is acting possessed—with flickering lights, malfunctioning power windows, a dead instrument cluster, or a security system that won’t cooperate—the root cause is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and seemingly unrelated issues. A trip to the dealership can result in a hefty bill for a new module and expensive programming fees. We offer a simpler, more affordable, and reliable solution.
From the Diagnostic Bay
We had a 2015 Silverado 1500 come into the shop with a complaint the owner called ‘the ghost.’ The dome lights would randomly turn on while driving, the radio would shut off, and occasionally the truck wouldn’t start, just a single click. We checked the battery and alternator, which were fine. After connecting our diagnostic tool, we saw multiple communication errors pointing toward the BCM. Instead of a costly new module from the dealer, we used our cloning service. By transferring the data from the original, failing unit to a replacement, we had the truck’s ‘ghost’ exorcised and running perfectly in a fraction of the time and cost. This is a classic failure pattern for this platform.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Horn, wipers, or radio malfunctioning without reason.
- ✔ False warning lights appearing on the instrument cluster (e.g., ‘Service Theft Deterrent System’).
- ✔ Communication errors with other vehicle modules, leading to no-start conditions.
- ✔ Rapid battery drain while the vehicle is parked.
Your Plug-and-Play 2015 Escalade ESV BCM Solution
This listing is for a replacement BCM that is professionally programmed with your vehicle’s specific data. Our service eliminates the need for any additional programming or calibration upon installation. We achieve this through a process called ‘cloning.’ You send us your original BCM, and we extract the vital vehicle-specific information—including the VIN, key data, and other settings—and flash it directly onto the replacement module. The result is a true plug-and-play part, ready to be installed as soon as you receive it.

- ✔ We’ll Contact You: After your order is placed, our team will reach out with detailed instructions on how and where to ship your original BCM. Please ensure your contact information is accurate.
- ✔ Ship Your Original Module: Package your original BCM securely and send it to us.
- ✔ We Program Your Replacement: Upon receiving your module, our technicians will perform the data transfer to the replacement unit within 1-2 business days.
- ✔ Receive Your Ready-to-Install BCM: We ship the fully programmed BCM back to you. Once it arrives, simply install it, and your vehicle’s electronic functions will be restored.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the airbag system with the BCM. This is only necessary if the light is on.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and traction control performance.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

This module is a direct replacement for the following part numbers: 13592137, 13506935, 13506936, 13587704, 13594764. Please verify that your original module carries one of these numbers.
Frequently Asked Questions
Why do I need to send you my original BCM?
Your original BCM contains the unique VIN, security information, and specific option coding for your vehicle. By cloning this data to the replacement unit, we create a true plug-and-play module that will work seamlessly without requiring a trip to the dealer for expensive programming.
Is this BCM difficult to install?
The physical installation is typically straightforward. On most compatible models like the Escalade ESV, Silverado, and Sierra, the BCM is located under the steering column on the driver’s side. It involves removing a few trim panels and connectors. However, we always recommend installation by a qualified technician.
How long does the programming service take?
Once we receive your original module, our technicians typically complete the cloning process and ship your replacement BCM within 1-2 business days. Total turnaround time will depend on shipping times to and from our facility.
What happens if I have an airbag light after installation?
This is not uncommon. It simply means the airbag module (SDM) needs to be re-synced with the new BCM. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. We require your original module for the data transfer service, but you do not need to worry about returning a core after the fact.
