2006 – 2011 Cadillac DTS Body Control Module (BCM) 20864767 – Programmed to Your VIN
Imagine cruising down the highway in your 2006-2011 Cadillac DTS, only to have the interior lights flicker erratically or the power door locks refuse to respond—classic signs of a failing Body Control Module. If you’re dealing with frustrating electrical glitches like these, or even diagnostic trouble codes such as DTC B1370 or U0140 popping up on your scanner, this pre-programmed BCM (part number 20864767) could be the straightforward solution you’ve been searching for. Tailored specifically to your vehicle using your VIN, it arrives flashed with the latest GM software updates, ensuring seamless integration and restored functionality. This module cross-references with numerous OEM numbers including 10382479, 15093910, and others, making it a versatile replacement for various GM models beyond just the DTS, such as the Impala or Tahoe. What sets it apart is the expert programming that tackles root causes like corrupted software or internal faults, preventing recurring issues and boosting overall vehicle reliability. In my two decades of diagnostics, I’ve seen how a properly matched BCM transforms erratic behavior into smooth operation, especially in luxury sedans like the DTS where comfort features are key.

Common Issues & How This Fixes Them
Body Control Modules in the 2006-2011 Cadillac DTS often fail due to age, water intrusion, or electrical surges, leading to symptoms that disrupt daily driving. For instance, you might notice intermittent power window operation or headlights that dim unexpectedly—these stem from faulty relay controls within the BCM. In one scenario I recall, a client with a 2008 DTS experienced random alarm activations, triggered by a corrupted security circuit, which this programmed replacement resolved instantly by recalibrating the system. Another frequent problem is no-start conditions linked to DTC P1629, where the anti-theft system locks out the engine; our VIN-specific flashing bypasses this by syncing perfectly with your immobilizer. Door locks failing to engage? That’s often a communication breakdown with the key fob, fixed here through updated software that strengthens signal processing. Don’t overlook dashboard warning lights or erratic gauge readings, which point to internal BCM shorts—replacing with this unit not only clears codes but prevents escalation to more costly repairs like wiring harness replacements. From my experience, addressing these early saves owners from stranded situations, especially during long trips where reliability matters most. If you’re troubleshooting “how to fix BCM failure on Cadillac DTS,” this module provides a direct, effective path forward with minimal downtime.
Easy Installation Guide
- Gather tools: You’ll need a socket set, trim removal tools, and your vehicle’s VIN ready for programming confirmation before shipment.
- Disconnect the battery: Safety first—remove the negative terminal to avoid electrical shorts during the process.
- Locate the BCM: In your 2006-2011 Cadillac DTS, it’s positioned on the right-hand center dash; carefully remove surrounding panels for access.
- Swap the module: Unplug the old BCM, connect the new pre-programmed unit, and secure it in place—double-check all connectors for a firm fit.
- Reconnect and test: Restore battery power, then cycle the ignition to verify basic functions like lights and locks.
- Perform theft deterrent relearn if needed: Only if a no-start issue arises post-install, insert the key, turn to ON for 10 minutes (engine off), then off for 5 seconds—repeat three times or until the security light extinguishes, per GM standards.
