Is Your GM Vehicle Plagued by Electrical Gremlins?
If you’re dealing with bizarre and frustrating electrical issues in your 2012 Chevrolet Cruze or another compatible GM vehicle, a failing Body Control Module (BCM) is the likely culprit. The BCM acts as the central nervous system for your car’s body electronics, controlling everything from power windows and door locks to interior lighting and the security system. When it starts to fail, it can create a cascade of seemingly unrelated problems that can be a nightmare to diagnose.
From the Diagnostic Bay
We once had a 2012 Chevy Cruze come into the shop with a list of complaints that sounded like a poltergeist had taken up residence. The dome light would flicker randomly, the driver’s side window would only work intermittently, and the radio would sometimes refuse to turn off even after the key was removed. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we found multiple communication error codes pointing to a breakdown in the network. The root cause? A faulty 2012 Cruze BCM. Instead of a complex and expensive rewiring job or a trip to the dealer for a new, un-programmed module, we used a cloned BCM. The customer was back on the road the same day with all issues resolved, saving hundreds of dollars and a major headache.
Common Symptoms of a Failing GM BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning windshield wipers or washers.
- ✔ Security system faults, anti-theft light flashing, or a no-start condition.
- ✔ False warnings appearing on the instrument cluster display.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Communication (U-series) trouble codes stored in the vehicle’s diagnostic system.
The Simple, No-Dealer-Visit Solution
Replacing a BCM isn’t just a matter of swapping parts. Each module is programmed with specific data for your vehicle’s VIN, options, and key information. A new module from the dealership requires expensive programming with specialized tools. Our unique mail-in service completely bypasses this step. We take the critical data from your original, failing BCM and transfer it directly to this replacement unit. When you receive it back, it’s a true plug-and-play solution.
How Our Programming Service Works:
- ✔ Place Your Order: Complete your purchase through our secure checkout.
- ✔ We’ll Contact You: We will reach out with simple instructions and the address to ship your original BCM to.
- ✔ Ship Your Module: Carefully package and send us your original BCM.
- ✔ We Program Your Part: Upon arrival, our technicians will professionally transfer all necessary data from your module to the replacement unit, typically within 1-2 business days.
- ✔ Receive Your Ready-to-Install BCM: We ship the programmed module back to you. Simply install it, and your vehicle’s functions will be restored.
Post-Installation Procedures for Your 2012 Cruze BCM
While our goal is a seamless plug-and-play experience, some GM vehicles may require a simple relearn procedure after the new BCM is installed. These are not always necessary but are good to be aware of:
- Airbag System Sync: In some cases, the airbag light may illuminate after installation. This indicates the new BCM needs to be synchronized with the SDM (airbag module). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be needed to ensure correct brake light operation and to satisfy the traction control system.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls many of the electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Why does this BCM need to be programmed?
The BCM stores your vehicle’s specific VIN, security information (for anti-theft), and settings for its various options. Our cloning service transfers this unique data, making the replacement module recognize your car and keys, avoiding a costly trip to the dealership for programming.
How does the mail-in cloning service work?
After you purchase, you will ship your original BCM to us. We will extract the data and flash it onto the replacement module. We then ship the programmed, ready-to-install module back to you.
Is this installation plug-and-play?
Yes, in over 95% of cases, the installation is completely plug-and-play. In rare instances, a simple relearn procedure, like for the airbag system, may be required as detailed in the product description.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary security information is stored within your original BCM, and we transfer that data directly. Your existing keys will work seamlessly with the replacement module.
