Restore Full Functionality to Your Vehicle’s Electronics
Is your Cadillac CTS or other GM vehicle plagued by bizarre electrical issues? Flickering lights, malfunctioning power windows and locks, or a persistent “Service Theft Deterrent System” message are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s proper operation.
From the Diagnostic Bay
We had a 2011 CTS in the shop where the owner had already replaced the driver’s side window motor and switch, but the window still wouldn’t work. Diagnostic scans showed no power from the BCM to the door module. Instead of continuing to replace parts, we swapped in a new BCM. Instantly, the window, locks, and interior lights started working perfectly. It’s a classic case of a single faulty module causing a cascade of seemingly unrelated issues.
Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Instrument cluster warning lights appearing randomly (e.g., ABS, Airbag, Security).
- ✔ The security system preventing the car from starting.
- ✔ Remote keyless entry (fob) not working correctly.
- ✔ Wipers or radio behaving unpredictably.

This module is a direct replacement for a wide range of part numbers, including 15828601, 22860591, 25892622, and many more, ensuring broad compatibility across numerous GM models.
Installation and Post-Install Notes
Physical installation is straightforward, typically involving locating the module (often in the dash area), disconnecting the battery, and swapping the electrical connectors. After installation, most functions will be immediately restored. However, in some cases, additional steps may be required:
- 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.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic features, such as power windows, locks, lights, wipers, security system, and keyless entry.
