2006 – 2011 Cadillac DTS Body Control Module (BCM) 15948439 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Have you ever jumped into your 2006-2011 Cadillac DTS only to find the power windows refusing to budge, or the interior lights acting up like they’re possessed during a late-night drive? These frustrating glitches often stem from a failing Body Control Module, disrupting everything from door locks to alarm systems. As a seasoned mechanic who’s diagnosed countless electrical gremlins in luxury sedans like the DTS, I’ve seen how a compromised BCM can turn a smooth ride into a headache, especially in older models exposed to years of humidity or voltage spikes. The good news? Our pre-programmed BCM, part number 15948439, arrives ready to install with the latest GM updates tailored to your VIN, clearing DTC codes and restoring seamless functionality. This unit matches a wide array of compatible part numbers including 10382479, 15093910, and more, ensuring broad fitment across GM vehicles. Beyond just swapping parts, it enhances overall electrical reliability, preventing issues like erratic wiper operation or false security alerts that could leave you stranded. In my shop experience, replacing with a VIN-matched module often resolves intermittent problems that generic fixes overlook, improving daily drivability and even towing stability if you’re hauling light loads.

Common Issues & How This Fixes Them
In the 2006-2011 Cadillac DTS, a faulty BCM often manifests as erratic electrical behavior—think non-responsive power seats, malfunctioning keyless entry, or dashboard warning lights that won’t quit. From my hands-on work, these stem from internal circuit degradation, often accelerated by moisture ingress or electrical surges, leading to DTC codes like P1629 or U0140 that disrupt communication with other modules. One client brought in a DTS where the headlights flickered randomly; scanning revealed BCM faults causing voltage inconsistencies, which not only annoyed but posed safety risks on highways. Installing our pre-programmed BCM fixes this by recalibrating the network, restoring stable power flow and clearing those codes for good. Another frequent headache is intermittent door lock failures, especially in humid climates, where the module’s relays wear out—our unit’s updated firmware strengthens these connections, enhancing security and convenience. For towing enthusiasts, a bad BCM might cause trailer light glitches, reducing reliability; this replacement ensures consistent signaling, improving safety during hauls. Expert tip: Always check for water damage around the RH center dash location in DTS models before replacement to avoid repeat issues. By addressing root causes with precise programming, you’ll notice smoother operation, fewer trips to the shop, and better overall vehicle performance, turning potential breakdowns into reliable drives.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates before shipping.
- Disconnect the battery to ensure safety and prevent electrical shorts during the process.
- Locate the BCM in the RH center dash of your Cadillac DTS and carefully remove the old unit by disconnecting connectors.
- Install the new BCM, reconnect all wiring, and secure it in place.
- Reconnect the battery and perform any necessary relearns: If a no-start condition occurs, conduct a theft deterrent relearn by cycling the key from off to on (without starting) for 10 minutes, three times. Additionally, reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure using a diagnostic tool, and recalibrate the brake pedal if your model requires it for optimal braking safety.
- Test all functions like lights, locks, and windows; consult your manual or a technician if variances arise.
