Is Your Chevy Cruze Experiencing Strange Electrical Issues?
The Body Control Module (BCM) is the central command center for your vehicle’s electronic accessories. When it begins to fail, it can cause a cascade of frustrating and seemingly unrelated problems. From power windows that won’t cooperate to a security system that prevents your car from starting, a faulty BCM can make your vehicle unreliable. If you’re tired of chasing electrical gremlins in your 2011 Cruze or other compatible GM vehicle, you’ve found the definitive solution.
This is not just a replacement part; it’s a comprehensive programming service for the 2011 Cruze BCM with part number 13578420. We eliminate the need for expensive dealership visits and complex programming tools. By cloning the data from your original module onto this replacement unit, we provide a true plug-and-play component that restores your vehicle’s functionality right out of the box.
We recently had a 2011 Chevy Equinox towed in that was causing its owner endless headaches. The key fob worked intermittently, the interior dome light would stay on, and occasionally, the vehicle would refuse to start, displaying a flashing security light. The owner had already replaced the battery to no avail. Our diagnostic scan revealed multiple communication loss codes (U-codes) all pointing to a failing BCM. Instead of a costly new module and programming fees at the dealership, we facilitated this cloning service. The customer shipped us their faulty BCM, we transferred the data, and sent the ready-to-install module back. It was a simple swap, and immediately, all the bizarre electrical issues were resolved. It’s the most efficient way to solve a complex problem.
Symptoms of a Failing Body Control Module
A failing BCM can manifest in various ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or not turning on.
- ✔ The vehicle’s security system engaging randomly, causing a no-start condition.
- ✔ The horn or alarm sounding without reason.
- ✔ Key fob failing to lock or unlock the doors.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ Multiple, unrelated warning lights appearing on the instrument cluster.

Important Post-Installation Information
While our cloning service makes this a plug-and-play installation, certain vehicle systems may require a recalibration procedure after the BCM is replaced. This is normal and ensures all related modules communicate correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to synchronize the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure accurate brake light operation and proper function of the traction control and stability control systems.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
How does this programming service work?
You purchase the service, ship your original BCM to us, and we transfer its unique data to a replacement module. We then ship the programmed, ready-to-install BCM back to you.
Do I need to take my car to a dealer after installation?
No. Our cloning service makes the replacement BCM plug-and-play, completely avoiding the need for dealership programming. In some rare cases, a simple relearn procedure like for the airbag system may be needed, which can be done by most independent shops.
What are the most common signs of a failing 2011 Cruze BCM?
The most common symptoms include erratic operation of lights, power windows, and door locks; a no-start condition with a flashing security light; and random alarms or horn sounds.
Is this a difficult part to replace?
On most compatible models like the Cruze, the BCM is located in the driver’s side or passenger’s side kick panel area. It is typically held in with a few bolts or clips and has several electrical connectors. Basic mechanical skill is all that’s required for the physical swap.
What happens if my airbag light comes on after I install it?
This indicates the BCM needs to be synchronized with the airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool to resolve this.
Do I need to send back my old part after?
No, there is no core charge for this service. You only need to send us your original module for the data cloning process. You can keep it afterward.
