2008 โ€“ 2013 Cadillac CTS Body Control Module (BCM) 15093910 – Programmed to Your VIN

Imagine cruising down the highway in your 2008-2013 Cadillac CTS, only to have your power windows fail suddenly or the interior lights flicker erraticallyโ€”classic signs of a faulty Body Control Module throwing DTCs like B1325 or U0140. As a seasoned automotive advisor with decades in diagnostics, I’ve seen this frustrate countless owners, often leading to costly dealership visits. Our pre-programmed BCM, part number 15093910, arrives ready for your exact vehicle, flashed with the latest GM updates using your VIN. It matches a wide array of interchangeable numbers including 10382479, 15276271, and 25892622, ensuring seamless compatibility across GM models like the CTS with LH or RH dash mounting. This isn’t just a replacement; it’s a reliable solution that restores full electrical harmony, preventing those nagging issues from disrupting your drive. By addressing root causes like voltage irregularities or communication losses, it delivers peace of mind and smoother performance, especially in demanding scenarios like city commuting or long trips.

  • Provides insightful value through included updates that prevent future breakdowns, drawing from years of hands-on experience in GM diagnostics.

Common Issues & How This Fixes Them

In my experience troubleshooting 2008-2013 Cadillac CTS models, Body Control Module failures often manifest as intermittent no-start conditions, where the engine cranks but won’t fireโ€”typically linked to DTC U0100 for lost communication with other modules. This stems from corroded connectors or internal circuit degradation, especially after exposure to road salt in winter climates. Another frequent headache is erratic power door locks or windows that refuse to operate, triggering DTC B1325 due to low battery voltage signals. I’ve helped owners who noticed their headlights dimming randomly during night drives, a symptom of BCM relay issues that can compromise safety.

This programmed BCM directly tackles these by restoring precise control over body functions. For instance, if you’re facing DTC B1370 related to the ignition switch circuit, the updated software ensures stable voltage distribution, preventing those frustrating stalls at stoplights. Real scenarios from my shop include a CTS owner towing a trailer who lost trailer brake lights mid-haul; replacing with this unit fixed the communication error instantly. It also addresses anti-theft system glitches, where the security light flashes endlesslyโ€”often resolved without full resets. By integrating the latest GM calibrations, it goes beyond basic fixes, offering long-term prevention against recurring codes and improving fuel efficiency through optimized accessory management. Always scan for codes first; if symptoms persist post-install, a simple battery disconnect can recalibrate.

Easy Installation Guide

  1. Provide your VIN immediately after purchase so we can program the BCM with the exact GM specifications for your 2008-2013 Cadillac CTS.
  2. Disconnect the negative battery cable to ensure safety and prevent electrical shorts during the process.
  3. Locate the BCMโ€”typically on the LH dash for most CTS modelsโ€”and remove the old unit by unplugging connectors and unbolting it carefully.
  4. Install the new BCM in the same position, securing it firmly and reconnecting all wiring harnesses without forcing connections.
  5. Reconnect the battery and perform a theft deterrent relearn if a no-start occurs: Insert key, turn to ON for 10 minutes (security light off), then off for 5 secondsโ€”repeat three times.
  6. Test all functions like lights, locks, and windows; clear any residual DTCs with an OBD-II scanner for optimal performance.
