Dealing with strange electrical problems in your 2015-2016 Chevrolet Impala? When lights flicker, windows stop working, or the security system acts up for no reason, the culprit is often a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can make your car feel unreliable and frustrating to drive. The dealership solution involves expensive diagnostics, a new module, and programming fees that can quickly add up, not to mention the hassle of getting your car there.
We offer a straightforward, cost-effective solution. This is a replacement BCM, part number 13594764, that comes pre-programmed using the data from your original module. This cloning service makes the replacement process simple: you send us your factory BCM, we transfer all the critical vehicle-specific data to this replacement unit, and we ship it back to you ready for installation. It’s a true plug-and-play fix that restores your car’s functionality without any need for a trip to the dealer.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Impala with a list of bizarre symptoms: the dome light wouldn’t turn off, the driver’s side power window worked intermittently, and the remote key fob was unresponsive. They had already replaced the battery and checked fuses with no luck. In my 20+ years as a technician, these disconnected electrical gremlins almost always point to a communication breakdown. After hooking up the scan tool, I saw multiple U-codes (communication fault codes) pointing back to the BCM. The module itself was failing internally, causing a data storm on the network. By replacing the BCM with a cloned unit, we restored all functions in under an hour of shop time, saving the customer from a costly and time-consuming dealer visit.
Common Signs of a Failing BCM
If your vehicle’s BCM is failing, you might notice one or more of the following issues. Confirming these symptoms can help you diagnose the problem with confidence.
- ✔ Erratic or non-functional interior and exterior lights (headlights, tail lights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Malfunctioning security system or anti-theft light staying on.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing without cause.
- ✔ Remote keyless entry (fob) failing to lock or unlock the doors.
- ✔ Communication DTCs (Diagnostic Trouble Codes), often in the U-series (e.g., U0100, U0140), stored in other modules.
A Straightforward Guide to Installation
Our cloning service simplifies the repair process. You get a fully functional module without the need for advanced diagnostic tools for programming.
- Step 1: Place your order and wait for our team to contact you with shipping instructions for sending us your original BCM.
- Step 2: Carefully disconnect the negative battery terminal. Locate and remove your original BCM. On the 2015-2016 Impala, it’s typically found on the left-hand (driver’s) side of the dash.
- Step 3: Securely package and ship your original module to us using the provided instructions.
- Step 4: Once we receive your module, we will clone the data to the replacement unit and ship it back to you, typically within one business day.
- Step 5: Install the pre-programmed BCM, reconnect all electrical connectors, and then reconnect the negative battery terminal. Start the vehicle and verify that all functions are restored.
Important Post-Installation Information
While our goal is a seamless plug-and-play experience, some vehicle systems may require a quick recalibration after the BCM is replaced. Please be aware of the following:
- ✔ Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and traction control function as expected.
Disclaimer: We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step of the process.

Frequently Asked Questions
What exactly is this cloning service?
Our cloning service involves transferring the essential data—like your vehicle’s VIN, security information, and specific options—from your original BCM to this replacement module. This makes the new part plug-and-play, eliminating the need for dealer programming.
Why is this better than just buying a used BCM from a junkyard?
A standard used BCM is programmed to a different vehicle. It will not work correctly in your car without being reprogrammed by a dealer, which is costly. Our service provides a part that is already matched to your specific vehicle.
Do I have to send my original BCM in?
Yes, sending us your original module is required. We need it to extract the unique data to program the replacement. This is what ensures a seamless, plug-and-play installation.
What if my airbag light comes on after I install it?
This can happen occasionally. It means the airbag control module (SDM) needs to be electronically ‘re-introduced’ to the new BCM. This procedure, called ‘Setup SDM Primary Key in BCM’, requires a professional-grade scan tool but is a quick process for any competent repair shop.
How long does the whole process take?
Once we receive your original BCM, we typically clone and ship the replacement unit within one business day. The total turnaround time will depend on shipping times to and from our facility.
Is there a core charge for my old part?
No, there is no core charge. After we clone the data, you can simply keep your original module.
