Restore Your Vehicle’s Electrical System with a Programmed BCM
Are you battling a storm of strange electrical problems in your 2015 Cadillac Escalade, Sierra, Silverado, or another compatible GM vehicle? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a no-start condition can often be traced back to a single, central component: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause widespread and frustrating issues. This isn’t just an inconvenience; it can compromise your vehicle’s safety and functionality. Don’t let a faulty module keep you off the road. We offer a reliable, straightforward solution with our programming service for the 2015 Escalade BCM, part number 13587704.
From the Diagnostic Bay
We recently had a 2015 Sierra 1500 towed in that was a complete electrical nightmare. The owner reported that one day the radio wouldn’t turn off even with the key out, the next day the power locks were cycling on their own, and finally, the truck wouldn’t start at all. The dash was dark, and it was acting completely dead. After checking the battery and main fuses, our scan tool couldn’t even communicate with half the modules. This pointed directly to a network communication failure originating from the BCM. We confirmed the BCM had power and ground, but it wasn’t communicating. By providing the customer with a BCM cloned from their original, we were able to restore all functions in under an hour of shop time, saving them a tow to the dealership and hundreds in diagnostic and programming fees.
Symptoms of a Failing Body Control Module
A failing BCM can manifest in numerous ways, often seeming like multiple unrelated problems. If your vehicle is experiencing any of the following, your BCM may be the culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic or inoperative interior and exterior lighting (headlights, taillights, dome lights).
- ✔ Malfunctioning instrument cluster gauges or warning lights.
- ✔ Security system issues, including false alarms or failure to recognize the key fob.
- ✔ Problems with the heating and air conditioning controls.
- ✔ A vehicle that cranks but refuses to start due to the BCM not activating the fuel pump or starter relay.
- ✔ Complete loss of communication with diagnostic scan tools.
The Simple, Plug-and-Play Solution
Dealerships will often charge a premium for a new BCM, followed by several hours of labor for installation and programming. Our service streamlines this entire process. We take a quality replacement BCM and transfer—or ‘clone’—the critical data from your original module directly onto it. This includes your vehicle’s VIN, mileage, security information, and specific option configurations. The result is a true plug-and-play module. Simply install it, and you’re back on the road without any need for expensive dealer-specific tools or additional programming.

Post-Installation Procedures
While our goal is a 100% plug-and-play experience, some modern GM vehicles have interconnected safety systems that may require a simple sync procedure after installation. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and can be performed with a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control performance.
Note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly is a ‘cloning’ or ‘programming’ service?
This service involves transferring the unique, vehicle-specific data (like VIN, mileage, and key information) from your original BCM to a replacement unit. This makes the replacement module a perfect electronic match for your vehicle, eliminating the need for dealership programming.
Why do I have to send you my original BCM?
Your original BCM holds all the essential data that makes your vehicle operate correctly. By sending it to us, we can extract this data and ensure the replacement BCM is a 100% plug-and-play solution, saving you hundreds of dollars in dealership fees.
Is this BCM difficult to install?
The physical installation is typically straightforward. The BCM is often located under the steering column or behind the dash on the driver’s side. Basic hand tools are usually all that’s required. The main benefit of our service is that no complex computer programming is needed after you install it.
What if an airbag light comes on after I install it?
This is a known possibility on some GM models. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
How long does the entire process take?
Once we receive your original module, our programming service typically takes 1-2 business days. The total time will depend on the shipping speed you choose to send your module to us and for us to return it.
Do I need to send my old part back for a core charge?
No, there is no core charge for this service. We will ship your original module back to you along with the newly programmed replacement. You can keep your original module.
