2006-2011 DTS Body Control Module 15299986 | Programmed to Your VIN

Restore Full Electronic Control to Your Cadillac DTS

Is your 2006-2011 Cadillac DTS acting possessed? Flickering lights, unresponsive power windows, or a security system that randomly goes off are more than just annoyances—they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command for your car’s comfort and convenience features. When it starts to fail, it can create a cascade of frustrating electrical gremlins. In my 20+ years as a technician, I’ve seen how a faulty BCM can make a luxury vehicle feel unreliable. This isn’t just a part; it’s the solution to getting your Cadillac’s sophisticated electronics working in harmony again.

We make this repair straightforward. This replacement Body Control Module arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. This critical step eliminates the need for an expensive trip to the dealership for programming. You get a reliable part that’s ready for installation right out of the box, saving you time, money, and hassle. Plus, with no core charge, you can keep your old part without any extra fees or return shipping to worry about.

Is Your Cadillac DTS Showing These Symptoms?

A failing BCM can manifest in many ways. If you’re experiencing any of the following, your BCM is the likely culprit:

• ✔ Power windows, mirrors, or door locks working intermittently or not at all.
• ✔ Interior or exterior lights staying on or not turning on.
• ✔ The anti-theft or security system acting erratically, sometimes causing a no-start condition.
• ✔ The horn sounding unexpectedly.
• ✔ Warning lights on the dash for systems like ABS or Airbags, often with communication codes (e.g., U0140, U0155).
• ✔ Inconsistent or non-functional remote key fob.

Your Straightforward BCM Installation Guide

Installing your new 2006-2011 DTS Body Control Module is a manageable job for a confident DIYer. For the DTS, it’s typically located behind the right side of the dashboard. Always consult a service manual for your specific vehicle, but here are the general steps:

1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
2. Access the Module: You will likely need to remove the glove box or lower dash trim panel on the passenger side to gain access to the BCM.
3. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
4. Install the New BCM: Mount the new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, and radio—to confirm proper operation.
6. Perform Relearns (If Needed): As noted in our post-install procedures, you may need a scan tool to perform an Airbag System Sync or a Brake Pedal Position Relearn if related warning lights appear.
