Restore Full Electronic Functionality to Your GM Vehicle
Is your 2015 Chevy Suburban, Tahoe, or Silverado plagued by bizarre electrical issues? Problems like flickering lights, unresponsive power windows, a malfunctioning security system, or random warning messages on the dash are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating and seemingly unrelated problems. This listing offers a reliable, plug-and-play solution: a replacement BCM programmed specifically for your vehicle using data from your original module.
The Simple, No-Dealer-Required Solution: Our Cloning Service
Forget about expensive dealership visits, towing fees, and complex programming procedures. Our professional cloning service makes this repair straightforward. Here’s how it works: after you place your order, you simply ship your original BCM to us. Our technicians will extract the unique, vehicle-specific data—including the VIN, key information, and factory-installed options—and flash it directly onto this replacement unit. We then ship the fully programmed module back to you. The result is a true plug-and-play component that restores your vehicle’s functions without any additional programming required on your end.
From the Diagnostic Bay
We had a 2015 Sierra 1500 come in with a classic parasitic battery drain. The owner had already replaced the battery twice and the alternator once, but the truck would still be dead after sitting for a day. After hours of tracing circuits, we found the BCM was failing to go into ‘sleep’ mode, keeping multiple systems active and draining the battery. A standard used BCM wouldn’t work due to the anti-theft system. By cloning his original module, we provided a cost-effective solution that fixed the drain and got him back on the road without a trip to the dealer for key programming.
Diagnosing Your 2015 Suburban BCM
A failing BCM can manifest in numerous ways, often making diagnosis tricky. If your vehicle is experiencing several of the following symptoms simultaneously, the Body Control Module is a likely culprit. This service provides a definitive fix for these common electrical gremlins.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior dome lights, headlights, or taillights staying on or not turning on.
- ✔ The security system or alarm randomly activating or failing to arm.
- ✔ Erratic gauge behavior or warning lights (like ABS or Airbag) on the instrument cluster.
- ✔ “Service Theft Deterrent System” message appearing on the driver information center.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Climate control or A/C system blower motor not functioning correctly.
Post-Installation Procedures
While our cloning service handles all primary programming, some vehicle systems may require a simple synchronization or relearn procedure after the new BCM is installed. These are often straightforward and can sometimes be required to ensure all systems communicate correctly.
- 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 airbag system with the new BCM and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Wide Compatibility Across GM Platforms
This BCM, identified by part numbers 13506935, 13592137, 13506936, 13587704, and 13594764, is compatible with a wide range of 2015 and newer GM vehicles. This includes popular models like the Chevy Silverado, GMC Sierra, Tahoe, Yukon, Escalade, Corvette, Impala, and Cadillac CTS, among others. Please verify the part number on your original module to ensure an exact match.
Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is the process of reading the critical vehicle-specific data (like VIN, mileage, and key codes) from your original BCM and writing it to the replacement module. This makes the new part a perfect digital match for your vehicle, ensuring it works immediately upon installation without dealer programming.
Why can’t I just install a used BCM from another vehicle?
A used BCM is programmed for a different vehicle’s VIN and security system. Installing it will cause a mismatch, likely preventing your vehicle from starting and causing other systems to malfunction. Our service eliminates this problem.
How long does the programming service take?
We typically complete the programming and ship your replacement BCM back to you within 1-2 business days of receiving your original module.
Do I need to send my keys along with the BCM?
No, you do not need to send your keys. All the necessary immobilizer and key data is stored within the BCM itself, and this information will be transferred during the cloning process.
What if my original BCM is water damaged or won’t communicate?
In many cases, even with physical damage, we can still recover the necessary data. However, if your module is severely damaged, please contact us before ordering to discuss the specifics of your situation.
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 can keep it afterward if you wish.
