Restore Your Impala’s Electrical System with a Hassle-Free Solution
Are you battling bizarre electrical issues in your 2015-2020 Chevrolet Impala? Flickering interior lights, power windows with a mind of their own, or a security system that randomly activates can be incredibly frustrating. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can create a cascade of problems that are difficult to diagnose. This is the definitive fix for your 2015-2020 Impala BCM, getting your car back to normal without the exorbitant dealership costs.
We offer a straightforward and reliable programming service. Instead of shipping you a blank module that requires expensive dealer-specific tools, we transfer the critical data from your original BCM to this replacement unit. This cloning process ensures the replacement module is a perfect match for your vehicle’s specific configuration, including the VIN and all factory-installed options. The result is a true plug-and-play solution that saves you time, money, and a trip to the service center.
Common Signs of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ The security or anti-theft system light stays on or prevents the car from starting.
- ✔ Erratic instrument cluster behavior, with gauges dropping out or warning lights appearing randomly.
- ✔ Communication failure diagnostic trouble codes (DTCs), such as U0140, U0155, or other U-codes.
- ✔ Wipers or turn signals operating incorrectly or not at all.
- ✔ Remote keyless entry (RKE) failing to respond.
From the Diagnostic Bay: The Case of the Haunted Impala
A customer brought in a 2017 Impala with a list of complaints that sounded like the car was possessed. The dome lights would flicker while driving, the radio would shut off, and occasionally, the car wouldn’t start, just a click. They had already replaced the battery. My initial scan showed a dozen intermittent communication codes across multiple modules. In my 20+ years as a technician, this pattern almost always points to one of two things: a major wiring issue or a failing BCM. The BCM acts as the network gateway. When it starts to fail internally, it floods the vehicle’s data bus with noise, causing other modules to drop offline. After confirming power and grounds to the BCM were solid, we recommended this exact cloning service. The customer sent us their module, we sent back the programmed replacement, and it solved every single issue. No expensive diagnostic rabbit holes, just a straightforward, effective repair.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2015-2020 Impala, the Body Control Module is typically located on the left-hand (driver’s side) of the dashboard, often behind the lower dash panel or near the steering column.
- ✔ Remove the Old Module: Carefully disconnect all electrical connectors from the BCM. Note their orientation. Then, unfasten any bolts or clips holding the module in place and remove it from the vehicle.
- ✔ Install the New Module: Mount your newly programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, wipers, and radio—to confirm the repair was successful.
Important Post-Installation Information
Our programming service makes this a simple swap, but with modern complex vehicles, a few extra steps might be needed. There is no core charge, so you can keep your original module.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is required. 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 may be needed to ensure flawless operation of the brake lights and traction control system.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified professional if you are unsure about any step.

No. Our service completely eliminates the need for any additional programming. Once you receive the module back from us, it’s ready to be installed and will function immediately.
How does the shipping process work?
After you place your order, we will contact you with detailed instructions and a shipping address. You will need to securely package and ship your original BCM to us. Once we complete the service, we ship your new programmed module back to you and provide a tracking number.
Where is the BCM located on my 2017 Impala?
For the 2015-2020 Impala, the BCM is located inside the cabin, on the driver’s side, attached to the left-hand side of the dash assembly. Access typically involves removing the lower dash trim panel.
Is this a guaranteed fix for my car’s electrical problems?
If your vehicle’s symptoms match those of a failing BCM and the module has been professionally diagnosed as the fault, this service provides a reliable and permanent solution. It addresses failures internal to the module itself.
