Tired of Your GM Vehicle’s Bizarre Electrical Problems?
Is your 2015 GMC Yukon or other GM vehicle acting possessed? One minute the wipers turn on by themselves, the next the radio won’t work, and dashboard warning lights are flashing like a holiday display. These aren’t just quirks; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s comfort and security features, and when it fails, it can cause a cascade of frustrating and unpredictable issues. A faulty BCM can make your reliable truck feel untrustworthy and leave you stranded.
Forget expensive dealership visits and the headache of programming a new module from scratch. We offer a simple, reliable solution: a replacement BCM programmed with your vehicle’s exact data. This isn’t just a part; it’s a complete, hassle-free fix. By cloning the information from your original BCM, we deliver a unit that is 100% plug-and-play. This restores full functionality and communication between all your vehicle’s systems, getting you back on the road with confidence.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Sierra 1500 with a laundry list of complaints: intermittent no-start, power locks cycling on their own, and the security light staying on. They had already replaced the battery and checked all the fuses. Diagnostics showed a flurry of U-codes (communication loss) with various modules. In my shop, I’ve seen this exact pattern dozens of times. We suspected the BCM wasn’t properly routing messages on the CAN bus network. By connecting our scope, we confirmed signal degradation originating from the BCM. Instead of a costly new module and hours of programming at the dealer, we provided a cloned 2015 Yukon BCM equivalent. The customer swapped it in their driveway in under an hour, and every single electrical gremlin vanished. It’s a textbook example of how a failing BCM can mimic multiple other problems.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security system light is on, or the alarm goes off randomly.
- ✔ The horn honks without reason or the wipers activate on their own.
- ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) appear intermittently.
- ✔ Communication error codes (U-codes) are stored, such as U0100, U0140, or U0155.
- ✔ The vehicle experiences intermittent no-start conditions, but the battery and starter are good.
A Straightforward Guide to BCM Installation
Our cloning service makes this repair accessible for both DIYers and professional techs. Since we handle all the programming, your job is a simple physical swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most compatible trucks and SUVs like the 2015 Yukon, the BCM is located under the driver’s side of the dashboard, often near the steering column or left firewall. Refer to your service manual for the exact position.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. They have locking tabs, so be gentle. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring each one clicks into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, windows, locks, wipers, etc.
Important Post-Installation Notes
While our BCM is designed for plug-and-play installation, some vehicle systems may require a quick sync-up procedure after the new module is installed. This is normal and depends on your vehicle’s specific configuration.
- 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 requires a professional-grade scan tool and syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
How does the programming service work?
It’s simple! After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the unique data and transfer it to your replacement module. We then ship the plug-and-play unit back to you, typically within 24-48 hours.
Do I need to send my keys?
No. Because we are cloning all the data from your original module, including the security information, your existing keys will work perfectly with the new BCM upon installation.
Is there a core charge or do I get my old BCM back?
There is absolutely no core charge. We ship your original BCM back to you along with the newly programmed replacement unit. You can keep it as a spare.
Will this fix my specific problem?
This part is a solution for a faulty BCM. If your vehicle is exhibiting common BCM failure symptoms like erratic electrical functions, communication codes, or security issues, this service is very likely the fix you need.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a bi-directional professional scan tool (like a Snap-on, Autel, or GM MDI). Many local repair shops can perform these quick procedures for a minimal fee if needed.
