Restore Full Electrical Function to Your Cadillac
Are you experiencing frustrating and unpredictable electrical problems in your 2010 Cadillac STS or other compatible GM vehicle? A failing Body Control Module (BCM) is often the culprit behind these baffling issues. The BCM acts as the central nervous system for your car’s body electronics, managing everything from your power windows and locks to your interior lights and security system. When it fails, it can create a cascade of problems that are difficult to diagnose.
This is a direct-fit replacement Body Control Module, part number 15948438, that arrives pre-programmed specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after your purchase, and our experts will flash the module with the latest GM software updates. This critical service means you can avoid a costly trip to the dealership for programming, making this a simple, plug-and-play solution.
From the Diagnostic Bay
We had a 2011 Cadillac DTS come into the shop with a list of complaints that seemed unrelated. The dome lights would flicker, the driver’s side window would work intermittently, and the key fob would randomly stop responding. The customer had already replaced the battery and checked fuses with no luck. After connecting our diagnostic scanner, we saw multiple communication fault codes pointing to the BCM. Instead of a dozen small problems, it was one central failure. Installing a VIN-programmed BCM like this one resolved every single issue at once, saving the customer hundreds in diagnostic time and parts.
Common Failure Symptoms
- ✔ Erratic or non-functioning interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing to operate.
- ✔ Warning lights appearing on the dashboard for no apparent reason.
- ✔ Intermittent failure of radio or climate control functions.
- ✔ A “No Communication” error when scanning with a diagnostic tool.
Solving the Problem with a Programmed 2010 STS Body Control Module
Don’t let a faulty BCM keep your luxury vehicle off the road. This replacement 2010 STS Body Control Module is your reliable and cost-effective solution. It is compatible with a wide range of GM vehicles (please see the full fitment list and cross-reference your original part number to ensure compatibility). By programming the unit to your VIN before shipping, we ensure it integrates seamlessly with your vehicle’s existing systems.
Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional steps to sync with other onboard systems. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light illuminates after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s VIN during checkout or by message, and it will arrive ready to install.
What does the Body Control Module do?
The BCM is a computer that controls most of your vehicle’s non-engine related electronic features, such as power windows, locks, lights, wipers, security system, and more.
How do I find my original part number?
Your original BCM’s part number is printed on a sticker on the module itself. You will need to locate the module in your vehicle (locations vary, see fitment list for common spots) and read the number directly from the unit to ensure a match.
What if the airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module.
