Is Your Vehicle Plagued by Electrical Gremlins?
Are you experiencing frustrating and unpredictable electrical issues in your Cadillac, Chevrolet, or GMC vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts on its own, or strange warning lights on the dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, coordinating everything from your interior lights and turn signals to your keyless entry and climate controls. When it starts to fail, it can make driving an unpredictable and annoying experience.
The Plug-and-Play Solution: A Pre-Programmed 2014-2015 CTS BCM
Replacing a BCM used to mean a costly trip to the dealership for both the part and the mandatory programming. This module eliminates that hassle. We offer a direct replacement BCM, part number 22915542 (also compatible with 22820314), that arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest, most stable software updates from GM, ensuring optimal performance and compatibility. This means no expensive scan tools or dealership appointments are required for programming—simply install the module, perform any necessary relearn procedures, and get your vehicle’s electronics working correctly again.
From the Diagnostic Bay
We had a 2015 GMC Acadia come into the shop with a laundry list of bizarre, intermittent problems. The customer complained that one day the radio wouldn’t turn off even with the key out, the next day the driver’s side power window wouldn’t work, and the liftgate would occasionally open on its own. We couldn’t find any wiring faults. After checking the data stream, we saw erratic communication from the BCM. Instead of a costly new module and programming at the dealer, we sourced a VIN-programmed unit like this one. The installation took less than an hour, and it instantly solved every single one of the customer’s electrical headaches. It’s a testament to how a single faulty module can wreak havoc on a modern vehicle.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (lights staying on or not turning on).
- ✔ Malfunctioning windshield wipers or horn.
- ✔ False alarms from the security system or issues with keyless entry.
- ✔ Warning lights on the dashboard, such as for the airbag or traction control system.
- ✔ Climate control system not responding correctly.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
Installation and Post-Installation Steps
This module is designed for a straightforward installation. Once you provide us with your VIN during checkout, we handle all the programming. When you receive the part, you simply disconnect the battery, locate and replace your old BCM (typically found under the driver’s side dashboard), and reconnect the battery. While our programming makes this a plug-and-play repair, some vehicles may require simple relearn procedures to sync with other systems.
Important Post-Installation Notes:
- Airbag System Sync: If the airbag warning light is illuminated 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. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure proper brake light and stability control function.
- No Core Charge: You are not required to return your old, faulty module. There is no core charge associated with this purchase.
This BCM is a reliable and cost-effective way to solve complex electrical issues and restore full functionality to your vehicle. By ordering a pre-programmed unit, you save significant time, money, and frustration compared to traditional repair methods.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. This Body Control Module comes fully programmed to your vehicle’s VIN before it ships. It is ready to install right out of the box, saving you a trip to the dealership.
What information do you need from me?
After you place your order, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot program or ship the module without it.
Where is the BCM located on my vehicle?
The location varies by model. On many vehicles like the Cadillac CTS, Acadia, and Traverse, it’s typically located on the left-hand side of the dashboard, near the steering column. On vans like the Savana and Express, it is often in the center dash area. Always consult a service manual for your specific vehicle.
My airbag light came on after I installed the new BCM. Is it defective?
No, this is a normal security procedure in some vehicles. The new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Does this part fit vehicles other than the 2014-2015 CTS?
Yes, this BCM is compatible with a wide range of GM vehicles, including the Chevy Impala, Traverse, Captiva Sport, Express Van, GMC Acadia, and Savana Van across various model years. Please check the detailed fitment list on this page to confirm compatibility with your exact vehicle.
