If your 2010 Cadillac STS is experiencing bizarre electrical issues, you’re not alone. As the central command center for your vehicle’s body electronics, a failing Body Control Module (BCM) can cause a cascade of frustrating and unpredictable problems. From power windows that won’t cooperate to security lights that flash for no reason, a faulty BCM can make your luxury vehicle feel unreliable. This isn’t just an inconvenience; it can be a matter of function and safety. That’s where we come in.

This is a direct-fit replacement Body Control Module, and we offer a professional Cloning Service to make your repair as simple as possible. Simply provide us with your vehicle’s VIN after purchase, and our technicians will program this module with the latest GM software specific to your 2010 Cadillac STS. This process transfers the vital data from your original unit, ensuring seamless integration. This means no expensive trips to the dealership for programming—just a straightforward installation to get your car back to normal.

Common Signs of a Failing BCM

If you’re experiencing any of these symptoms, a faulty BCM is the likely cause. A proper diagnosis is key, but these are the tell-tale signs we see in the shop every day:

• ✔ Erratic or non-functional power windows, door locks, and mirrors.
• ✔ Interior or exterior lights staying on or not working at all.
• ✔ The security system light is illuminated, or the vehicle won’t start due to an anti-theft issue.
• ✔ Wipers behaving unpredictably or not parking in the correct position.
• ✔ Multiple communication Diagnostic Trouble Codes (DTCs), such as U0100, U0140, or U0155.
• ✔ The horn sounding randomly or not working when pressed.

A Straightforward Guide to Installation

Installing your new 2010 STS Body Control Module is a manageable job for a confident DIYer or any professional mechanic. With our cloning service, the most complex part—the programming—is already done.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
2. Locate the BCM: On the 2010 Cadillac STS, the Body Control Module is typically located in the center dash area. You may need to remove a lower dash panel for access.
3. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
4. Install the New Module: Mount the new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, wipers, etc.
6. Perform Relearns (If Needed): Start the vehicle. If an airbag light or brake system warning appears, a post-install procedure like the Airbag System Sync or Brake Pedal Position Relearn may be required using a professional scan tool.

Post-Installation Requirements

While our cloning service makes this a near plug-and-play repair, some vehicle systems may require recalibration for safety and proper function.

• ✔ Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible diagnostic tool.
• ✔ Brake Pedal Position Relearn: On some models, this relearn is necessary to ensure the brake lights and traction control system function correctly.
