2011 – 2013 GMC Sierra Body Control Module (BCM) 15093910 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
As a veteran mechanic who’s wrenched on GM trucks for decades, I’ve watched 2011-2013 GMC Sierra drivers battle frustrating electrical glitches – think erratic power windows, unresponsive key fobs, or dashboard lights that won’t quit flashing. What if your Sierra’s doors refuse to lock during a harsh winter storm, leaving you vulnerable? Or how do you fix intermittent no-start conditions tied to a faulty BCM in your 2011 GMC Sierra? These headaches often stem from a worn Body Control Module, the brain behind your vehicle’s body functions. Our pre-programmed BCM, featuring part number 15093910 among compatible options like 10382479, 25892622, and 22860591, arrives ready to install after we flash it with your VIN for seamless GM updates.

Common Issues & How This Fixes Them
In my shop experience, 2011-2013 GMC Sierra owners frequently report BCM failures triggered by moisture ingress or voltage spikes, common in regions with extreme weather shifts. One classic symptom? Your interior lights stay on indefinitely, draining the battery overnight – often linked to corrupted module data that our pre-flashed unit resolves by resetting communication protocols. Another issue hits hard: faulty door locks or windows that fail intermittently, caused by degraded internal circuits; replacing with this BCM restores precise control, clearing related DTC codes like P1629 or U0140 for good.
Then there’s the dreaded airbag warning light that illuminates post-fault, stemming from BCM-SDM mismatches. This replacement integrates seamlessly, allowing a quick reset to maintain safety features. For towing enthusiasts, erratic trailer brake signals can compromise hauls – our module stabilizes these, improving response times and reliability. I’ve seen cases where a failing BCM causes no-start scenarios due to theft deterrent glitches; this unit minimizes that by supporting easy relearns. Overall, it addresses root causes with updated firmware, preventing recurrence and saving on diagnostic fees. Users often notice smoother performance immediately, like reliable remote starts in cold mornings.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the newest GM updates tailored to your 2011-2013 GMC Sierra.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap.
- Locate the BCM (typically under the steering column or in the dash) and remove the old unit by unplugging connectors carefully.
- Install the new BCM, reconnect all wiring, and secure it in place.
- Reconnect the battery and perform necessary relearns: If no-start occurs, initiate theft deterrent relearn by cycling the key on for 10 minutes, off for 10 seconds, repeating three times.
- Use a diagnostic tool for airbag light reset via the ‘Setup SDM Primary Key in BCM’ procedure, and recalibrate the brake pedal if your model requires it for optimal braking safety.
