Restore Your Vehicle’s Electrical System with a Perfectly Matched BCM
Are you dealing with baffling electrical issues in your vehicle? Flickering lights, malfunctioning power windows, or a car that refuses to start can often be traced back to a single component: the Body Control Module (BCM). As the central nervous system for your car’s electronics, a failing BCM can cause widespread chaos. This isn’t just an inconvenience; it can be a significant safety concern. We offer a straightforward, reliable solution with our pre-programmed 2013 Spark BCM, designed to get you back on the road without the exorbitant costs and headaches of dealership programming.
Our unique service simplifies the entire repair process. Instead of shipping you a blank module that requires specialized tools and software, we handle the complex part for you. Simply purchase this service, and we’ll contact you with instructions to ship your original BCM to our facility. Our expert technicians will then clone all the essential data—including VIN, mileage, and key information—onto this fully tested replacement module. The result? A BCM that is truly plug-and-play for your vehicle, ready for installation right out of the box.
From the Diagnostic Bay: The Case of the Erratic Equinox
A customer brought in a 2012 Equinox with a laundry list of complaints: the radio would turn on and off by itself, the dome light wouldn’t work, and occasionally the turn signals would stop flashing. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw several ‘U’ codes, indicating a loss of communication between modules. In my 20+ years of experience, this pattern almost always points to the BCM. Instead of a costly new unit from the dealer, we used our cloning service. By transferring the data from his old, failing BCM to our replacement, the vehicle was back to normal in a day. It’s a perfect example of how a cloned 2013 Spark BCM or its equivalent can solve complex issues simply.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the culprit. This module, when failing, can throw communication codes like U0140, U0155, or specific circuit codes related to the functions it controls.
- ✔ Unpredictable power windows, door locks, or interior/exterior lights.
- ✔ Horn sounding randomly or not working at all.
- ✔ Security system faults or anti-theft light staying on.
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Dash warning lights appearing and disappearing without reason.
- ✔ Wipers or climate control operating erratically.
Your Straightforward BCM Installation Guide
Installing your programmed BCM is a manageable task for a confident DIYer. Follow these general steps for a successful replacement.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- Locate the BCM: On a 2013 Spark, the BCM is typically found in the left lower A-pillar area. For other models, its location varies (see fitment list). Consult a service manual if you’re unsure.
- Remove Trim Panels: Carefully remove any plastic trim or kick panels necessary to access the BCM. Use a trim removal tool to avoid breaking clips.
- Disconnect and Remove: Unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Start the vehicle and test all functions controlled by the BCM—lights, locks, windows, wipers, etc.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- 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 relearn might be necessary to ensure correct brake light operation and traction control functionality.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified professional if you are uncertain about any step.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to mail your original BCM to us. We then extract the vehicle-specific data and transfer it to the replacement module. We ship the programmed module back to you, ready for installation.
Do I need to send my keys?
No, you do not need to send your keys. Our cloning process transfers all the necessary key information from your original module, so your existing keys will work seamlessly.
Is this a plug-and-play solution?
Yes, for over 95% of installations. Because we clone your original data, no initial programming is needed. However, as noted, some vehicles may require a minor relearn procedure for systems like the airbags or brake pedal sensor if a warning light appears after installation.
What is the turnaround time?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. Return shipping tracking will be provided as soon as it’s on its way back to you.
Do I have to pay a core charge?
No, there is no core charge for this service. You can keep your original module after we have completed the cloning process.
Will this fix my specific problem?
This BCM will fix issues directly caused by a faulty Body Control Module. If you are experiencing symptoms like erratic lights, door locks, windows, or communication error codes (U-codes), this is very likely the solution. Proper diagnosis is always recommended.
