Restore Full Electronic Control to Your Vehicle
Is your Cadillac CTS or other compatible GM vehicle exhibiting bizarre electrical behavior? Flickering lights, malfunctioning power windows, or a security system that won’t cooperate are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement BCM, part number 22820314 (also compatible with 22915542), is the definitive solution to restore your vehicle’s proper function and reliability.
We take the guesswork and dealership hassle out of the equation. Unlike a standard off-the-shelf part, this module is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that the BCM communicates correctly with all other modules in your car, preserving all your original features and settings. Simply provide your VIN after purchase, and we’ll handle the complex programming, sending you a part that is ready for a much simpler installation process.
From the Diagnostic Bay
We had a 2014 Cadillac CTS in the shop that was driving the owner crazy. The horn would blare randomly, the interior lights would stay on, and occasionally the car wouldn’t start, citing a security issue. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors pointing towards a network failure. The culprit? A failing BCM. Instead of a costly trip to the dealer for a new module and programming fees, we installed one of our pre-programmed units. The car immediately returned to normal, and all the electrical gremlins were gone. It’s a perfect example of how a single component can cause widespread chaos, and how the right part makes for a straightforward fix.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lamps staying on, draining your battery.
- ✔ The vehicle’s security system preventing the engine from starting.
- ✔ Dashboard warning lights appearing intermittently without a clear cause.
- ✔ Windshield wipers or turn signals activating on their own or not working when prompted.
- ✔ Inconsistent or non-functional climate control blower motor.
- ✔ Key fob not being recognized by the vehicle.
Installation and Setup for Your 2014-2015 CTS BCM
This BCM is a direct replacement for the original unit in a wide range of GM vehicles, including the 2014-2015 Cadillac CTS, Chevy Traverse, GMC Acadia, and more. Because we program it with the latest GM software updates using your VIN, the installation is significantly simplified. However, after installing the new module, some vehicles may require one or more relearn procedures to ensure all systems are synchronized. These are standard procedures that can be performed by a qualified technician with a professional-grade scan tool.
Post-Installation Procedures:
- ✔ Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM). This is only required if the light is on.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed. This ensures the brake lights function correctly and the traction control and stability systems operate as designed.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance. Best of all, there is no core charge for this part. You can keep your original module.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, locks, lights, wipers, security system, and climate control fans. It’s the brain for your car’s body electronics.
Is this part a direct fit for my 2014-2015 CTS BCM?
Yes, this module is a direct-fit replacement for part number 22820314 in the 2014-2015 Cadillac CTS and many other GM models listed in the fitment chart. Providing your VIN ensures we program it correctly for your specific vehicle options.
Why do you need my VIN number?
Your VIN allows us to program the BCM with the exact software and calibrations for your vehicle’s specific features, such as keyless entry, lighting packages, and security settings. This makes the installation process much smoother and avoids a trip to the dealership for programming.
Will I need to do anything after installing this BCM?
While the BCM comes pre-programmed, some vehicles may require a ‘relearn’ or ‘sync’ procedure for systems like the airbags or brake pedal position sensor. This is a standard step that a technician with a professional scan tool can perform if necessary.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old BCM back to us, which saves you time and shipping costs.
