Restore Control and End Electrical Chaos in Your Cadillac
Are you dealing with baffling electrical issues in your 2006-2011 Cadillac DTS? One minute the power windows work, the next they don’t. The security light flashes for no reason, or the radio cuts out intermittently. These aren’t random quirks; they’re classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can turn your luxury ride into a source of constant frustration. This replacement Body Control Module, part number 15276271, is the definitive solution, arriving pre-programmed with the latest GM software specifically for your vehicle’s VIN.
From the Diagnostic Bay: The Case of the Haunted Cadillac
I remember a 2008 DTS that came into my shop with a list of symptoms that sounded like a ghost story. The owner was frustrated, having already replaced the battery and checked all the fuses. The dome lights would flicker, the key fob would work sporadically, and the dash would light up with random warnings. A quick scan showed a slew of U-codes, indicating a network communication breakdown. This pointed directly to the BCM. Instead of a costly, time-consuming dealer visit, we installed a VIN-programmed module just like this one. The communication network stabilized instantly, all the gremlins vanished, and the customer drove away with a car that behaved like new. This part saves time, money, and diagnostic headaches.
Is Your Vehicle Showing These BCM Failure Signs?
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or won’t turn on at all.
- ✔ A security system that prevents the car from starting or triggers the alarm randomly.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Key fob not responding or working intermittently.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, often starting with ‘U’ (e.g., U0140, U0155).
- ✔ Features like heated seats or the radio not functioning correctly.
A Straightforward Guide to Your BCM Installation
Installing your new 2006-2011 DTS Body Control Module is a manageable job for a confident DIYer. Since we program the module to your VIN before shipping, you can skip the expensive trip to the dealership for software flashing.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the 2006-2011 Cadillac DTS, the BCM is typically located behind the glove box or on the right-hand side of the center dash area. You may need to remove the glove box assembly for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt the module from its mounting bracket.
- Install the New Module: Mount the new BCM in place and securely reconnect all electrical harnesses. Ensure each plug is fully seated.
- Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- Perform Final Steps: Start the vehicle and check for proper function of all accessories. Note the post-installation procedures below, as some relearn steps may be necessary.
Important Post-Installation Information
After installing your new BCM, your vehicle may require one or more of the following procedures to ensure all systems operate correctly. This is a normal part of the process.
- 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: To ensure accurate brake light operation and traction control function, a brake pedal position sensor recalibration may be required.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for your specific model’s requirements.

Frequently Asked Questions
Do I need to program this 2006-2011 DTS Body Control Module?
No! We handle the programming for you. Simply provide your vehicle’s VIN during checkout, and we will flash the module with the latest GM software before it ships. This makes installation much simpler.
Where is the BCM located on my Cadillac DTS?
On the 2006-2011 Cadillac DTS, the BCM is generally found behind the glove box, on the right side of the center dash. Access typically requires removing the glove box assembly.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us, saving you time and hassle.
What if my airbag light comes on after installation?
This is not uncommon. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A professional technician with a compatible scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
