If you’re dealing with the frustrating and unpredictable electrical gremlins in your 2015 Chevrolet Suburban 1500, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable vehicle into a source of constant headaches. From power windows that won’t roll down to a security system that randomly immobilizes your engine, the symptoms are often confusing. This isn’t just an inconvenience; it can be a major safety and reliability issue.
Forget the expensive trip to the dealership and the complex programming they require. We offer a straightforward, reliable solution: a mail-in cloning service for your BCM. You simply ship us your original module, and we transfer all its critical data—including VIN, mileage, and key information—to this fully tested replacement BCM, part number 13594692. We then ship the ready-to-install module back to you. The result is a true plug-and-play fix that restores your vehicle’s full functionality without any additional programming or key relearns needed on your end. It’s the most efficient way to solve the problem correctly the first time.
A Technician’s Notebook: The Suburban with a Mind of Its Own
I remember a customer bringing in a 2015 Suburban. The complaint was ‘it’s possessed.’ The dome lights would flicker while driving, the radio would shut off, and occasionally the horn would blare when they used the turn signal. They had already replaced the battery and checked the main grounds. After connecting my scan tool, I saw multiple ‘U’ codes, indicating communication loss with the BCM. Instead of a $1200+ dealership bill for a new module and programming, we used this exact cloning service. The customer sent their module out, got the programmed replacement back in a few days, and installed it in their driveway. The ‘possessed’ Suburban was cured, and all for a fraction of the dealer cost.
Is Your GM Vehicle Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security system light stays on, or the vehicle won’t start intermittently.
- ✔ The horn honks randomly, or the windshield wipers activate on their own.
- ✔ Instrument cluster gauges behaving strangely or not working at all.
- ✔ Diagnostic Trouble Codes (DTCs) such as U0140 (Lost Communication With Body Control Module) are present.
- ✔ Inconsistent A/C and climate control operation.
Your Straightforward BCM Installation Guide
Once you receive your programmed module from us, installation is simple. On most compatible trucks and SUVs like the 2015 Suburban, the BCM is located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: Remove the lower dash panel beneath the steering wheel to access the module. It’s a black box with several large multi-pin connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the Replacement: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors.
- Final Steps: Reinstall the dash panel and reconnect the negative battery terminal. Start the vehicle to confirm that the electrical issues are resolved.
Important Post-Installation Note: In some cases, you may need to perform a couple of simple relearn procedures. If your airbag light is on, a professional scan tool is needed for the ‘Setup SDM Primary Key in BCM’ function. Additionally, a ‘Brake Pedal Position Relearn’ might be required for proper brake light and traction control function. These requirements can vary by exact model and year.
