Is Your Chevy Cruze Experiencing Electrical Gremlins?
If you’re dealing with bizarre and frustrating electrical issues in your 2011 Chevrolet Cruze, GMC Terrain, Buick Regal, or Cadillac SRX, a faulty Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights and security system. When it starts to fail, it can create a cascade of seemingly unrelated problems that are impossible to ignore.
The Solution: A Programmed Replacement BCM
Instead of paying for expensive diagnostics and programming at a dealership, our service provides a straightforward and cost-effective solution. We take a fully tested, replacement BCM and program it using the data from your vehicle’s original module. This cloning process ensures that the replacement unit is a perfect match for your car’s specific configuration and options. The result is a true plug-and-play module that restores full functionality without any additional programming required on your end.
From the Diagnostic Bay
We recently had a 2011 GMC Terrain in the shop that was driving its owner crazy. The horn would honk randomly, the wipers would activate on a sunny day, and the instrument cluster lights would flicker intermittently. The owner had already replaced the battery and checked every fuse with no success. After connecting our diagnostic tool, we saw multiple communication fault codes all pointing to the BCM. By providing a programmed replacement 2011 Cruze BCM (which is cross-compatible), we were able to resolve all the phantom issues. The key was cloning the original data, which preserved all the vehicle-specific settings and avoided a complicated setup process at the dealer.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ The vehicle’s security system or keyless entry malfunctioning.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Warning lights on the dashboard, such as the airbag or security light.
- ✔ Communication errors with other vehicle modules when scanned with a diagnostic tool.

Important Post-Installation Information
While our goal is a seamless plug-and-play experience, some GM vehicles may require a simple relearn procedure after the new 2011 Cruze BCM is installed. These are not signs of a defective part but are standard vehicle security and safety handshakes.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be required to ensure proper operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
Why do I need to send you my original BCM?
Your original BCM contains vital data specific to your vehicle’s VIN, mileage, and optional features. By cloning this data to the replacement module, we ensure it is 100% plug-and-play and avoids the need for expensive dealership programming.
Is this BCM compatible with my vehicle?
This module is a direct replacement for several part numbers, including 13577850, 13505326, 13500384, 13574844, 13504004, 13504494, and 13578420. Please check the fitment list and match your part number to ensure compatibility.
How long does the service take?
Once we receive your original module, our programming and testing process is typically completed within 1-2 business days. We will then ship the replacement module back to you.
What if the airbag light comes on after I install the part?
This is a normal security procedure on some GM vehicles. A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do I need to return my old part after I receive the replacement?
No, there is no core charge for this service. You only need to send us your original module for the initial data cloning. We do not require it back afterward.
