2011 – 2013 GM – Body Control Module (BCM) 15276271 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with that frustrating moment when your 2011-2013 GM vehicle’s lights flicker unexpectedly, or the power windows refuse to budge during a rainy drive? You’re not alone—I’ve seen countless owners of models like the Chevy Impala or GMC Savana facing these glitches, often tied to a failing Body Control Module. Questions like “Why won’t my GM BCM clear DTC codes for electrical faults?” or “How to fix intermittent no-start in my 2011 GMC Yukon?” pop up frequently in my shop. This pre-programmed BCM, featuring part number 15276271 among compatible ones like 25892622 and 20815898, arrives flashed with the latest GM updates using your VIN. It tackles those issues head-on, restoring seamless control over body functions and improving overall system reliability. In my experience, swapping to this unit not only clears persistent trouble codes but also enhances features like remote start consistency, especially in heavy-duty vans used for towing.

- Backed by a one-year warranty with no core return needed, giving peace of mind for owners troubleshooting dashboard warnings.

Common Issues & How This Fixes Them
A faulty BCM in 2011-2013 GM vehicles often manifests as erratic behavior, like doors not locking properly or interior lights staying on, draining the battery overnight. From my diagnostics over the years, these stem from internal module corrosion or software glitches, common in humid climates affecting models like the Chevy Tahoe. Another frequent headache? DTC codes like P0601 or U0140 that won’t clear, leading to failed emissions tests or towing unreliability in Savana vans. This replacement BCM resolves that by providing updated firmware, effectively resetting communication networks and preventing signal losses. I’ve advised clients with Cadillac Escalade models experiencing no-crank scenarios—often misdiagnosed as battery issues—where a fresh BCM restores starter engagement and improves fuel efficiency monitoring. For those asking “What’s causing my GM Traverse power seat failures?”, it’s usually BCM relay control breakdown; this unit fixes it by recalibrating outputs, ensuring smoother operation and reducing repair costs long-term. Always scan for codes first to confirm, as early intervention avoids cascading failures in connected systems.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with GM’s latest updates before shipping.
- Disconnect the battery to ensure safety, then locate the BCM—typically under the steering column in Tahoes or center dash in Express vans.
- Remove the old unit by unplugging connectors and mounting screws; install the new one in reverse order.
- Reconnect the battery and perform any required relearns: For theft system, if no-start occurs, cycle the key from off to on (without cranking) 3 times, waiting 10 minutes each—only needed if symptoms persist.
- Reset the airbag warning via ‘Setup SDM Primary Key in BCM’ using a diagnostic tool; recalibrate brake pedal if your model requires it for optimal stopping power.
- Test all body functions like lights and locks; consult your manual or a tech for vehicle-specific variations to avoid oversight.
