Is Your GM Vehicle Acting Possessed? The BCM is Likely the Culprit.
If you’re experiencing a frustrating array of electrical gremlins in your 2015-2020 Chevrolet Impala or another compatible GM vehicle, a failing Body Control Module (BCM) is often the root cause. The BCM acts as the central nervous system for your car’s body electronics, controlling everything from your power windows and locks to your interior lighting, security system, and even communication between other critical modules. When it starts to fail, the symptoms can be unpredictable and maddening, making your vehicle unreliable and difficult to use.
Instead of facing a costly trip to the dealership for a new module and expensive programming fees, we offer a simple, effective, and affordable solution. This listing is for a replacement BCM (part number 13594692) that is fully programmed using the data from your original, failing module. This cloning service makes the replacement process as close to plug-and-play as possible, restoring your vehicle’s full functionality without the dealership hassle.
From the Diagnostic Bay
We had a 2016 Silverado in the shop last month with the strangest set of symptoms. The customer reported that sometimes the radio wouldn’t turn off after he shut the truck off, the dome lights would flicker randomly while driving, and the key fob would only work intermittently. He’d already replaced the battery and checked all the fuses. We ran a full diagnostic scan and found multiple communication error codes pointing towards the BCM. Instead of a new unit, we performed a cloning service just like this one. After installing the programmed replacement, every single one of his bizarre electrical issues vanished. It’s a perfect example of how a failing BCM can cause a cascade of seemingly unrelated problems.
Common Symptoms of a Failing BCM
A faulty Body Control Module can manifest in numerous ways. If you’re noticing any of the following issues, it’s a strong indicator that your BCM needs attention:
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or not working.
- ✔ The security system or alarm malfunctioning, or the vehicle not starting due to a security lockout.
- ✔ The key fob failing to lock or unlock the doors consistently.
- ✔ Dashboard warning lights appearing for no reason (e.g., ABS, Airbag, Traction Control).
- ✔ The radio or infotainment system behaving strangely or not turning off with the ignition.
- ✔ Horn honking unexpectedly or not working when pressed.

This service ensures the replacement BCM is a perfect electronic match for your vehicle, preserving all original functions and avoiding the need for complex and expensive dealer-only tools for initialization.
Post-Installation Procedures
While our goal is a plug-and-play installation, some modern GM vehicles require a simple sync or relearn procedure after a BCM is replaced. Please be aware of the following potential requirements:
- 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 new BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
