Are you chasing electrical gremlins in your 2015-2020 Chevrolet Impala? Flickering lights, malfunctioning power windows, a horn that has a mind of its own, or a dashboard lit up with random warnings are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it starts to fail, it can cause a host of frustrating and seemingly unrelated problems. A trip to the dealership often means a hefty bill for a new module plus expensive programming fees. We offer a smarter, more affordable solution.
This listing is for a professionally programmed BCM, compatible with part number 13594769 and others. Our unique cloning service makes this repair straightforward. Simply send us your original BCM, and we will transfer all of its critical data—including your vehicle’s VIN, security information, and specific options—to this replacement unit. The result is a true plug-and-play module that is ready for installation right out of the box, eliminating the need for dealership intervention. Restore your Impala’s functionality and peace of mind with a reliable, expertly prepared component.
Case Study: A Tricky Diagnosis
A customer brought in a 2018 Impala with a laundry list of complaints: the radio would randomly shut off, the driver’s side power window worked intermittently, and the anti-theft light would stay on, sometimes preventing the car from starting. They had already replaced the battery and checked fuses with no luck. On the scan tool, I saw a dozen communication loss codes (U-codes) pointing to multiple modules. In my 20+ years of experience, when you see that many unrelated communication faults, the issue is almost always the central hub—the BCM. We confirmed the diagnosis, performed our cloning service, and the customer had their car back the next day with every single issue resolved. This service saved them from a potential $1000+ dealership bill.
Is Your Impala Showing These BCM Failure Signs?
- ✔ Unpredictable power door lock or window operation.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system engaging randomly, causing a no-start condition.
- ✔ Inoperative remote keyless entry (RKE) functions.
- ✔ False warnings on the instrument cluster (e.g., ‘Service Airbag,’ ‘Service StabiliTrak’).
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other B-series codes.
- ✔ Horn blaring or wipers activating without user input.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2015-2020 Impala, the BCM is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- ✔ Remove Connectors: Carefully disconnect all electrical harness connectors from the old BCM. Each connector has a locking tab that must be depressed or a lever that needs to be moved to release it. Do not force them.
- ✔ Swap the Module: Unbolt or unclip the original BCM from its mounting bracket and remove it from the vehicle. Install your newly programmed module in its place.
- ✔ Reconnect Everything: Securely plug all electrical connectors into the new BCM. You should hear or feel a click as they lock into place. Reconnect the negative battery terminal.
- ✔ Perform Post-Install Checks: Start the vehicle and verify that all body functions (lights, windows, locks, etc.) are operating correctly. See the ‘Important Post-Installation Notes’ section below for potential relearn procedures.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a final handshake to fully sync with the new BCM. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required. This must be done with a professional-grade scan tool to sync the airbag system with the BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light operation and to keep the traction control system happy. This is also performed with a scan tool.
Disclaimer: These procedures can vary. We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to our facility. Our technicians will then extract the unique data from your module and flash it onto the replacement unit. We then ship the ready-to-install module back to you.
Do I need to send my keys?
No. Because we are cloning your original module’s data, the replacement will recognize your existing keys, saving you the hassle and cost of key reprogramming.
Is there a core charge?
No, there is no core charge or need to return your original module after the service. You can keep it.
What is the turnaround time?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. You will receive a tracking number as soon as it ships.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is non-functional in the vehicle, we can still recover the necessary data on our bench-top equipment. Please contact us with details about your module’s condition if you have concerns.
