Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you dealing with baffling electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). In my 20+ years in the shop, I’ve seen how a bad BCM can turn a reliable car into a source of constant frustration. The dealer solution is often a new module followed by a steep bill for programming. We offer a smarter, more affordable path forward.
This is a comprehensive cloning service for your BCM. Instead of selling you a blank module that leaves you stranded, we transfer the critical data from your original BCM directly onto this replacement unit. This means your vehicle’s VIN, security information, and specific options are perfectly preserved. The result? A true plug-and-play module that requires no additional programming upon installation. Simply send us your original module, and we’ll handle the complex technical work, shipping you back a ready-to-install solution.
From the Diagnostic Bay: The Spark EV That Baffled Everyone
A few months back, a 2015 Spark EV was towed into the shop. The owner was at his wit’s end. The instrument cluster would randomly go dark, the radio would shut off, and he was getting intermittent ‘Service Vehicle Soon’ messages. He’d been to two other places, and the dealership had quoted him over $1,200 for a new BCM and the labor to program it. After connecting my scan tool, I found a slew of U-codes (communication errors) pointing to the BCM. Instead of a costly replacement, we had him send us his original module. Within a day of receiving it, we cloned his data to one of our tested units and shipped it back. He installed it himself in under 30 minutes. The car started right up, all gremlins gone. He saved hundreds of dollars and the headache of a dealership visit.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ Vehicle security system faults or random alarm activation.
- ✔ Instrument cluster warning lights appearing without cause.
- ✔ Communication Diagnostic Trouble Codes (DTCs) like U0140, U0155, or other ‘U’ codes stored in various modules.
- ✔ Problems with the keyless entry or push-to-start systems.
Your Straightforward Installation Guide
Installing your programmed 2014-2016 Spark BCM is a direct swap. While the location varies slightly across the models this part fits, the process is generally the same.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the BCM: On the 2014-2016 Spark EV, the BCM is typically found behind the trim panel at the left lower A-pillar (near the driver’s kick panel). For other models, consult your service manual for the exact location (e.g., LH dash, RH cowl).
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or clips holding the module in place and take it out.
- Install the New Module: Seat your newly programmed BCM in the same location and secure it with the original hardware. Reconnect all electrical connectors, ensuring they click securely into place.
- Power Up: Reconnect the negative battery terminal. Your vehicle is now ready to start with its functions restored.
Important Post-Installation Checks
In some cases, additional synchronization procedures may be needed after installation. This is normal and ensures all vehicle systems communicate correctly.
- 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. This is only required if the light is on.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration might be necessary on certain models.
Disclaimer: We always recommend consulting a factory service manual or a certified technician if you are unsure about any step. There is no core charge for this part; you can keep your original module.

Frequently Asked Questions
How does this programming service work?
How does this programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will clone its data to the replacement module and ship it back to you, usually within 1-2 business days. This makes the new part plug-and-play.
Do I need to program this BCM at the dealer?
No. The main benefit of our service is that we handle all the programming. The module you receive will be ready to install right out of the box, with no need for expensive dealer tools or software.
Is this a guaranteed fit for my 2014-2016 Spark BCM?
Yes, this is a guaranteed fit for the 2014-2016 Chevrolet Spark EV. It also fits a wide range of other GM vehicles. Please check the compatibility list and match your original part number to ensure a perfect fit.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data for cloning. Please contact us with the specifics of your module’s failure, and our technicians can advise on the likelihood of a successful data transfer.
Do I need to send my keys with the module?
No, you do not need to send your keys. Our cloning process transfers the existing key information from your old BCM to the new one, so your current keys will work seamlessly after installation.
