Restore Full Electrical Function to Your Vehicle
Is your Chevrolet Sonic or other GM vehicle plagued by strange and unpredictable electrical problems? Issues like flickering lights, malfunctioning power windows, a dead instrument cluster, or a car that won’t start can often be traced back to a single, critical component: the Body Control Module (BCM). The BCM acts as the central command center for your car’s body electronics. When it fails, it can create a cascade of frustrating issues that are difficult to diagnose. This listing offers a reliable and straightforward solution: a replacement BCM, part number 13592137, that comes pre-programmed with your vehicle’s original data.
From the Diagnostic Bay
We recently had a 2017 Chevy Sonic in the shop with a baffling set of symptoms. The customer reported that the horn would go off randomly, the radio would shut down, and the anti-theft light was always flashing. They had already replaced the battery and checked every fuse with no luck. A standard code reader showed nothing, but our advanced diagnostic tools revealed a series of ‘U’ codes, indicating a communication breakdown between modules. The culprit was an internally failing BCM. By providing a cloned Chevy Sonic Body Control Module, we were able to resolve all the bizarre electrical gremlins at once, saving the customer from an expensive and lengthy diagnostic process at the dealership.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior dome lights, headlights, or taillights staying on or not turning on.
- ✔ The security system engaging randomly, preventing the car from starting.
- ✔ Erratic behavior from the windshield wipers or horn.
- ✔ False warning lights appearing on the dashboard (e.g., “Service Theft Deterrent System”).
- ✔ Complete loss of communication with the module, leading to a no-start condition.
- ✔ Inconsistent A/C and climate control operation.
Our Simple Plug-and-Play Programming Service
Dealerships will often charge a premium for a new BCM and then add several hours of labor for programming it to your vehicle. Our service eliminates that hassle and expense. The process is simple:
- Place Your Order: Purchase this BCM programming service. Ensure your contact information is up-to-date.
- We Contact You: We will reach out with instructions on how to ship your original BCM to our facility.
- We Clone Your Data: Once we receive your module, our technicians will extract all the critical vehicle-specific data—including the VIN, key information, and factory options—and flash it onto a fully tested replacement unit.
- We Ship It Back: We ship your original module and the newly programmed replacement back to you, ready for installation.
This cloning process makes the replacement a true plug-and-play part. There is no need for any additional programming or key relearning procedures. Just install the module, and you’re ready to go.
Installation and Post-Install Notes
On the 2015-2018 Chevrolet Sonic, the BCM is located in the right-hand rear quarter panel. While installation is generally straightforward, please be aware of potential post-installation requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the systems.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light function and traction control performance.
We always recommend consulting a factory service manual or a qualified technician for specific guidance. There is no core charge for this service; you can keep your original module.

Frequently Asked Questions
What is a BCM cloning service?
We transfer the unique, vehicle-specific data (like VIN, mileage, and key information) from your original Body Control Module to a replacement unit. This makes the new module a direct plug-and-play solution, avoiding expensive dealership programming.
Why do I have to send you my original part?
Your original BCM contains the security and operational data that is essential for your car to function correctly. We need it to extract this information and ensure the replacement module works perfectly with your existing keys and systems.

Once we receive your original module, our programming service typically takes 1-2 business days. We then ship both your original and the newly programmed replacement back to you. Total turnaround time will depend on shipping speeds.
Will I need to have my keys reprogrammed?
No. Because we clone all the data from your original module, the replacement will recognize your existing keys immediately without any additional programming.
Is this part difficult to install?
For a 2015-2018 Sonic, the BCM is in the RH rear quarter panel. The physical replacement is straightforward for those with basic mechanical skills. However, always be prepared for potential post-installation electronic procedures as noted in the description.
