Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating and unpredictable electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or even a car that won’t start can all point to a single culprit: a failing Body Control Module (BCM). As the central command for your car’s comfort and convenience features, a faulty BCM can make driving a nightmare. This service offers a reliable and straightforward fix for your Programmed GM BCM, eliminating the need for costly dealership visits and complex programming procedures.
We simplify the repair process. This listing is for a replacement BCM, part number 13580696, which we will professionally program by cloning the data from your original module. Simply purchase this service, ship your original BCM to us, and we’ll handle the rest. We transfer all the essential vehicle-specific information to the replacement unit, making it a true plug-and-play part. Once the cloning is complete, we ship the ready-to-install module back to you with tracking information. It’s the most efficient way to get your car back to 100% functionality.
From the Diagnostic Bay: The Case of the Confusing Equinox
A customer brought in their 2012 Chevy Equinox with a list of bizarre symptoms: the radio would turn on by itself, the dome lights wouldn’t turn off, and the battery was dead every morning. They had already replaced the battery twice. A quick scan showed a dozen communication codes, primarily a U0140 (Lost Communication With Body Control Module). Instead of just throwing parts at it, we tested the BCM’s power and ground circuits, which were solid. The issue was internal to the module itself. By providing a cloned Programmed GM BCM, we solved all the electrical gremlins in one go. The customer avoided a tow to the dealer and saved hundreds on diagnostic and programming fees.
Common Signs Your Body Control Module is Failing
A failing BCM can cause a wide range of symptoms that may seem unrelated. If your vehicle is exhibiting any of the following, your BCM might be the cause:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system alarm sounding randomly or the key fob not working.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ A no-start condition where the engine cranks but won’t fire up.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or other U-codes.
- ✔ Problems with the heating and A/C controls.
A Straightforward Guide to Your BCM Installation
Once you receive your programmed module from us, the physical installation is a simple swap. While the BCM’s location varies by model, the general process is consistent.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: The BCM is typically found under the dashboard on the driver’s or passenger’s side, often behind a kick panel or the glove box. (Refer to the fitment list for common locations).
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, windows, locks, etc.—to confirm the repair was successful.
Important Post-Installation Information
In some cases, minor follow-up procedures may be needed to ensure all systems are perfectly synced. This is normal and depends on your specific vehicle’s configuration.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system. This is only necessary if the light is on.
- Brake Pedal Position Relearn: Certain models may require a brake pedal position sensor recalibration to ensure the brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician for procedures specific to your make and model.

Frequently Asked Questions
How does the mail-in cloning service work?
After you place your order, we will contact you with detailed instructions on how to ship your original BCM to our facility. Once we receive it, our technicians will transfer the data to the replacement module and ship it back to you, typically within 1-2 business days.
Do I need to do any programming myself?
No. The purpose of our cloning service is to handle all the programming for you. The BCM you receive will be pre-programmed with your vehicle’s specific data, making it ready for installation right out of the box.
What if my original BCM is completely dead or unreadable?
In the majority of cases, even with significant internal failure, we can still extract the necessary data. If for some reason your module’s data is completely corrupted and unrecoverable, we will contact you to discuss options, which may include a full refund.
Is this a guaranteed fix for my car’s problems?
This service corrects issues directly caused by a faulty BCM. While the symptoms listed are strong indicators, it’s crucial to have your vehicle properly diagnosed. We guarantee our programmed module will function correctly, but we cannot guarantee it will fix problems stemming from other parts of the vehicle (e.g., bad wiring, faulty sensors).
Do I need to send my keys with the BCM?
No, you do not need to send your keys. The programming data we clone is related to the vehicle’s options and security settings stored within the BCM itself, not the key transponders.
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.
