2008 – 2012 – BCM (BCM) 15880684 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic door locks or dashboard lights flickering unexpectedly in your 2008-2012 GM vehicle, leaving you puzzled during a rainy commute? You’re not alone—many owners face these frustrations when the Body Control Module (BCM) starts failing, often triggering diagnostic trouble codes like P1629 or B1370. What if replacing it could restore smooth operation and clear those persistent DTCs? Our pre-programmed BCM, part number 15880684, arrives ready for your specific ride, flashed with the latest GM updates using your VIN. Compatible with a wide array of models including Chevy Impala, GMC Yukon, Cadillac DTS, and more from the fitment list, it matches OEM numbers like 10382479, 20815898, and 25892622. This isn’t just a swap; it’s a reliability boost that enhances electrical system stability, improves anti-theft functionality, and even aids in better fuel efficiency by optimizing accessory controls. Drawing from over two decades in diagnostics, I’ve seen how a faulty BCM can mimic wiring issues, leading to costly misdiagnoses—our unit prevents that by integrating seamlessly, often resolving intermittent no-start problems tied to immobilizer glitches.
Common Issues & How This Fixes Them
One frequent headache is malfunctioning power windows or locks that refuse to respond, often caused by BCM corrosion from moisture ingress in models like the 2008-2012 Chevy Express vans. This can strand you with inaccessible doors during emergencies, but our pre-programmed BCM restores full control, clearing related DTC codes and preventing recurrence through updated firmware.
Another issue hits hard in colder climates: dashboard warning lights staying illuminated, such as the airbag or security indicators, stemming from BCM communication failures in vehicles like the GMC Savana. Ignoring this risks safety system deactivation; our module fixes it by recalibrating sensors, ensuring compliance with GM standards and improving overall vehicle responsiveness.
Towing enthusiasts with 2010 Tahoe or Yukon models often report erratic trailer lighting, linked to BCM relay faults that disrupt signal processing. This not only affects visibility but can lead to towing unreliability—replacing with our VIN-matched unit stabilizes outputs, enhances load management, and clears codes like U0140 for safer hauls.
In high-mileage Impalas, intermittent wiper or headlight failures arise from degraded BCM circuits, exacerbating night driving hazards. Our solution integrates the newest updates, mitigating these by optimizing power distribution and extending component lifespan.
Finally, some owners experience battery drain from phantom electrical draws, common in Enclave or Traverse SUVs. This BCM replacement identifies and isolates faulty loops, promoting energy efficiency and reducing jump-start frustrations.

Easy Installation Guide
- Provide your VIN after purchase so we can pre-program the BCM with the exact GM updates for your vehicle.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap.
- Locate the BCM—typically under the steering column in Tahoes or center dash in Express vans—and remove the old unit by unplugging connectors carefully.
- Install the new BCM, reconnecting all harnesses securely, then reconnect the battery.
- Perform post-install procedures: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and recalibrate the brake pedal if your model requires it for optimal safety and performance.
- Test all functions like lights, locks, and accessories; consult your manual or a tech if variances occur, as steps can differ by model.
