Restore Full Functionality to Your GM Vehicle
Are you battling frustrating electrical gremlins in your 2015 Tahoe, Sierra, or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows, a dead radio, or a security system that acts on its own are often 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 confusing and unpredictable problems. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. Our professionally programmed BCM, part number 13587704, is the definitive solution to get your vehicle back to 100% without the exorbitant costs and hassle of a dealership visit.
From the Diagnostic Bay
We had a 2015 Silverado 1500 in the shop that was driving the owner crazy. The dome lights would randomly turn on while driving, the power door locks would cycle on their own, and the instrument cluster would occasionally go dark. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes pointing towards the BCM. Instead of a costly new module and hours of programming, we used our cloning service. We transferred the data from his faulty BCM to our replacement unit. The installation took less than 30 minutes, and every single electrical issue was resolved instantly. It’s a powerful fix that saves customers time, money, and headaches.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Malfunctioning key fobs or remote start system.
- ✔ The vehicle’s security or anti-theft system engaging randomly.
- ✔ False warnings appearing on the instrument cluster (e.g., ‘Service Airbag’).
- ✔ Radio or infotainment system issues, such as not turning on or off correctly.
- ✔ Inconsistent windshield wiper operation.

Post-Installation Information
While our goal is a 100% plug-and-play experience, some GM systems require a ‘handshake’ after a new module is introduced. Be aware of these potential, easy-to-resolve procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is performed with a professional scan tool and syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be necessary to ensure perfect brake light and traction control operation.
Always consult a factory service manual or a qualified technician for specific guidance related to your vehicle.
Frequently Asked Questions
Why is cloning my original BCM better than buying a new one from the dealer?
Cloning transfers all your vehicle’s specific data, including VIN, mileage, and key fob information, to the replacement module. This avoids the expensive and time-consuming programming required by a dealership for a new BCM, making it a true plug-and-play solution.
How long does the programming service take?
We typically complete the data transfer and ship your modules back out within 1-2 business days of receiving your original BCM.
Will my existing keys and remotes work immediately?
Yes. Because we clone the security information from your original module, your current keys and remote fobs will work exactly as they did before, with no additional programming needed.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. Please contact us before ordering if your module is severely damaged by water or fire, or if it has no communication whatsoever.
Is this part compatible with other part numbers?
Yes, this BCM is a direct replacement for several part numbers, including 13592137, 13506935, 13506936, 13587704, and 13594764.
