Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you chasing down bizarre electrical gremlins in your GM vehicle? One minute the power windows work, the next they don’t. Maybe your dash is lit up with warning lights, or the car refuses to start intermittently. As a technician with over two decades of diagnostic experience, I’ve seen these exact symptoms hundreds of times, and they almost always point to a failing Body Control Module (BCM). This isn’t just an annoyance; a faulty BCM can compromise security, lighting, and even safety systems. Instead of facing a costly trip to the dealership for diagnostics and programming, we offer a simple, reliable fix.
This is a professionally programmed BCM that is a direct-fit replacement for part number 13501739 and many others. Our unique cloning service makes this a true plug-and-play repair. Simply purchase this module, and we’ll contact you with instructions to ship your original BCM to our facility. Our experts will transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. We then ship it back to you, ready for installation without any need for expensive dealer tools. You get a fully functional module, and you even get to keep your original part—no core charge required.
A Technician’s Notebook: The Case of the Confused Cruze
I had a 2012 Chevy Cruze come into my bay that was driving the owner crazy. The radio would turn on and off by itself, the turn signals worked only when they felt like it, and the key fob was unresponsive. The owner had already replaced the battery and checked all the fuses. A quick scan showed a flurry of U-codes (U0140, U0155), indicating a loss of communication between modules. This is a classic sign that the BCM, the central hub for all these body functions, is failing internally. Instead of a complex rewiring job, the solution was a pre-programmed BCM. Once installed, all the random electrical issues vanished instantly. This service provides that same definitive fix without the diagnostic headache.
Is Your Vehicle Showing These Symptoms?
A failing BCM can cause a wide range of issues that seem unrelated. If you’re experiencing any of the following, this module is likely the solution you need.
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ Key fob not working or intermittent remote start failure.
- ✔ Unexplained warning lights on the dashboard, such as ‘Service StabiliTrak’ or ‘Service Airbag’.
- ✔ The engine won’t crank or starts intermittently, even with a good battery.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0100, or U0155.
- ✔ Horn, wipers, or other accessories activating on their own.
A Straightforward Guide to Your BCM Installation
Installing your new Programmed GM BCM is a simple process. After receiving the module with your vehicle’s data already loaded, follow these steps. The BCM is typically located in the driver’s or passenger’s side kick panel or dash area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: Depending on your model (e.g., driver’s kick panel in a Cruze, LH dash in an SRX), find the original Body Control Module. It will have several large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all the electrical connectors securely into the correct ports.
- Reconnect Power: Reattach the negative battery terminal and tighten it.
- Verify Functionality: Start the vehicle and test all the functions that were previously malfunctioning—windows, locks, lights, radio, etc.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play process, some vehicle systems may require a quick sync-up after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional scan tool to sync the airbag module with the new BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly. This is also performed with a capable scan tool.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified automotive technician if you are unsure about any step.

Frequently Asked Questions
How does the programming service work?
It’s simple! After you place your order, we will email you instructions and a shipping label to send your original BCM to us. We then extract the vehicle-specific data and transfer it to the replacement module. We ship the new module back to you, ready to install.
Is this a plug-and-play part?
Yes. Because we clone the data from your original module, this replacement BCM is 100% plug-and-play. No additional programming or trips to the dealer are required for it to function.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within your original BCM and will be transferred during our cloning process.
What is the turnaround time?
We typically program and ship your replacement module within 1-2 business days of receiving your original BCM. You will receive a tracking number as soon as it ships.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, we can still extract the necessary data. If your module has severe water or fire damage, please contact us first to discuss options.
Is there a core charge?
No, there is no core charge for this service. You can keep your original module after you’ve installed the replacement.
