Is Your 2010 Buick or Chevy Experiencing Bizarre Electrical Issues?
If your 2010 Buick Allure, LaCrosse, or Chevy Camaro is suddenly acting possessed—with flickering lights, malfunctioning power windows, a dead instrument cluster, or a no-start condition—the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s electronic accessories, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. A trip to the dealership can result in a hefty bill for diagnostics, a new module, and expensive programming fees. We offer a direct, cost-effective solution.
This listing is for a replacement BCM, compatible with part numbers 13500385, 13577268, and 13578421, that is fully programmed to your vehicle’s specific configuration. Our unique mail-in programming service uses the data from your original module to create a true plug-and-play replacement. This process ensures that all your vehicle’s original features and security information are retained, eliminating the need for any additional on-vehicle programming by a dealer.
We had a 2010 Camaro owner come to us completely frustrated. His power locks would cycle randomly, the radio would shut off, and occasionally the car wouldn’t start, showing a ‘Service Theft Deterrent System’ message. He had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication error codes pointing to the BCM. Instead of a costly new module and programming at the dealer, we performed our mail-in service. We cloned his original BCM data to one of our replacement units. He installed it in under 15 minutes, and every single one of his strange electrical gremlins vanished. It’s a textbook case of how a failing BCM can wreak havoc on an otherwise healthy vehicle.
Diagnosing Your 2010 Allure Body Control Module
A faulty BCM can be difficult to diagnose because its symptoms often mimic other issues, like a bad battery or a faulty alternator. However, if you’re experiencing several of the following problems simultaneously, your BCM is the most likely cause.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The instrument cluster (gauges, warning lights) behaving erratically or going completely dark.
- ✔ The radio or climate control system turning on and off by itself.
- ✔ A ‘Service Theft Deterrent System’ message and a no-start condition.
- ✔ Inaccurate fuel gauge or other sensor readings.
- ✔ Key fob not working to lock/unlock doors.

Installation and Post-Installation Notes
Physical installation is simple. On the 2010 Allure and LaCrosse, the BCM is located in the driver’s side (LH) kick panel. On the 2010 Camaro, it’s located behind the passenger side (RH) of the dashboard. Simply disconnect the battery, unplug the electrical connectors from the old BCM, remove it, and install the new one in its place. Reconnect the connectors and the battery.
While our programming makes this a plug-and-play solution, some GM vehicles may require a couple of simple relearn procedures after installation:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This is a quick process that can be performed by any shop with a professional-grade diagnostic tool. It syncs the new BCM with the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation. This is also a simple procedure done with a scan tool.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
Why do I need to send you my original BCM?
Your original BCM contains critical data specific to your vehicle, including the VIN, security keys for the anti-theft system, and settings for your car’s options. By cloning this data to the replacement module, we create a true plug-and-play part that won’t require a trip to the dealer for expensive programming.
Is this BCM a guaranteed fix for my vehicle?
This service corrects issues caused by a faulty 2010 Allure Body Control Module. While the symptoms listed are strong indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before ordering.
How long does the entire process take?
Once we receive your original module, the programming and processing time in our facility is typically 1-2 business days. The total time will depend on the shipping times to and from our location.
What if the airbag light comes on after I install the new BCM?
This is not uncommon. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system. A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool. Any competent repair shop can do this for you.
Do I need to return my old BCM after I receive the new one?
No, there is no core charge for this part. You only need to send us your original module for the initial data cloning. We will ship it back to you along with your newly programmed replacement.
