2006 – 2011 Cadillac DTS Body Control Module (BCM) 20935349 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Think about that frustrating moment when your 2006-2011 Cadillac DTS starts acting up—doors won’t lock properly, interior lights stay on, or the security system triggers false alarms right when you’re rushing to an appointment. These glitches often trace back to a failing Body Control Module (BCM), the central hub managing everything from power windows to anti-theft features in your luxury sedan. If you’ve been searching “how to fix intermittent electrical issues in Cadillac DTS” or “replacing BCM to clear DTC codes like B1370,” you’re in the right spot. Our pre-programmed BCM, part number 20935349, arrives ready for your vehicle, flashed with the latest GM updates using your VIN for seamless compatibility. It matches a wide range of OEM numbers including 10382479, 15093910, and more, ensuring it fits models like the Equinox 07-09, Impala 06-12, and specifically your DTS with its RH center dash location. This isn’t just a swap; it’s a reliable solution that restores smooth operation, improves overall electrical reliability, and prevents those nagging check engine lights from disrupting your drive. Drawing from over two decades in auto diagnostics, I’ve seen how a fresh BCM can transform a temperamental DTS into a dependable cruiser, especially in harsh winter conditions where moisture accelerates module failures.

Common Issues & How This Fixes Them

In my years working on GM vehicles like the Cadillac DTS, I’ve diagnosed countless BCM-related problems that leave owners stranded or annoyed. One common headache is erratic door locks and power accessories—caused by degraded internal circuits in the module, leading to communication breakdowns with the vehicle’s network. This can trigger DTC codes such as U0140 or B1325, making your DTS feel unreliable during daily commutes. Another issue hits the lighting system: headlights or interior lamps flickering, often due to voltage regulation failures in aging BCMs, which worsens in cold weather as components contract and fail. Security system malfunctions are also frequent, where the anti-theft immobilizer prevents starting, mimicking a dead battery but actually stemming from corrupted BCM software. Replacing with our VIN-matched BCM clears these DTC codes efficiently, restores proper signal processing, and enhances towing reliability if you use your DTS for light hauling. For instance, a client with a 2008 DTS reported constant alarm triggers; post-replacement, the system stabilized, and we avoided costly dealership visits. This fix goes beyond basics—it optimizes power distribution, potentially improving fuel efficiency by ensuring accessories don’t draw unnecessary current. If you’re dealing with “Cadillac DTS BCM replacement to fix no-start condition,” this module addresses root causes with GM’s latest firmware, reducing recurrence risks.
