2010 Sts Body Control Module 15921352 Programmed To Your VIN VIN BCM

Restore Full Functionality to Your Vehicle’s Electronics

If you’re dealing with baffling electrical issues in your Cadillac STS or another GM vehicle—like flickering lights, malfunctioning power windows, or a security system that has a mind of its own—a failing Body Control Module (BCM) is often the culprit. As the central command center for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and seemingly unrelated problems. I’ve seen it countless times in the shop: a vehicle comes in with a list of electrical gremlins that have stumped other mechanics, and a proper diagnosis points directly to this critical component.

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and dealer-level expense out of the equation. By providing us with your vehicle’s VIN at checkout, you will receive a 2010 STS Body Control Module that is professionally flashed with the latest GM software specific to your car. This ensures seamless integration and restores the precise functionality you’ve been missing, without the need for an expensive trip to the dealership for programming.

Is Your Vehicle Showing These Symptoms?

• ✔ Intermittent or non-working power windows, door locks, or interior lights.
• ✔ Erratic windshield wiper or horn operation.
• ✔ Key fob not being recognized or inconsistent remote start function.
• ✔ ‘Service Security System’ or similar warnings on the dash.
• ✔ Unexplained battery drain when the vehicle is off.
• ✔ Communication errors with other vehicle modules, leading to a no-start condition.

A Straightforward Guide to Installation

Installing your new BCM is a manageable job for a confident DIYer or a quick task for a professional. For the 2010 Cadillac STS, the BCM is typically located in the center dash area. Always consult a service manual for the exact location on your specific model.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system’s capacitors to discharge.
2. Access the Module: Carefully remove the necessary dash panels or trim to gain access to the old BCM. The location is noted in the fitment list for many models.
3. Disconnect and Remove: Unplug all electrical connectors from the old BCM. They have locking tabs, so be gentle. Once disconnected, unbolt or unclip the module from its mounting bracket.
4. Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
5. Post-Installation Procedures: Reconnect the battery terminal. While the module is pre-programmed, some vehicles require additional steps. You may need a diagnostic tool to perform the ‘Setup SDM Primary Key in BCM’ to clear any airbag lights and a ‘Brake Pedal Position Sensor Calibration’ to ensure proper brake light and stability control operation.
6. Test Everything: Start the vehicle and test all body functions: lights, wipers, locks, windows, and key fob commands to confirm a successful repair.
