2010 GMC Yukon XL 1500 Body Control Module (BCM) 15837419 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2010 GMC Yukon XL 1500 suddenly refusing to start on a cold winter morning, or noticed the interior lights flickering erratically during a family road trip? These frustrating electrical glitches often trace back to a failing Body Control Module (BCM), disrupting everything from power windows to security systems. As a seasoned auto tech who’s diagnosed countless GM trucks, I’ve seen how a faulty BCM can trigger diagnostic trouble codes (DTCs) like U0140 or B1370, leaving you stranded or facing hefty repair bills. The good news? Our pre-programmed BCM, part number 15837419, arrives ready to install with the latest GM software updates tailored to your VIN. It matches numerous interchangeable numbers, including 20815898 and 25892622, ensuring broad compatibility across models like the Tahoe, Suburban, and Express vans. This direct replacement clears persistent DTC codes, restores smooth operation, and boosts overall vehicle reliabilityโespecially crucial for towing heavy loads in your Yukon XL.

Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, I’ve encountered owners of the 2010 Yukon XL 1500 battling intermittent no-start conditions, where the engine cranks but won’t fireโoften due to a BCM failing to communicate with the immobilizer system. This stems from internal circuit degradation or exposure to moisture, common in regions with harsh winters. Another frequent headache is erratic power accessories, like windows that roll down unexpectedly or headlights that dim without warning, caused by BCM relay failures triggering codes like B3109. Then there’s the airbag warning light staying illuminated, which could signal a deeper safety module mismatch, compromising occupant protection during collisions. Our pre-programmed BCM resolves these by restoring proper network communication, effectively clearing DTCs and recalibrating systems. For instance, one client towing a boat noticed improved stability after replacement, as it fixed voltage inconsistencies that affected trailer brakes. By integrating the latest firmware, it also enhances towing reliability, preventing overloads on electrical circuits. If you’re asking, “Why does my Yukon XL’s security light flash randomly?”โa faulty BCM is likely the culprit, and this unit provides a reliable fix, drawing from real-world diagnostics to prevent future breakdowns.
Easy Installation Guide
- Provide your VIN after purchase so we can flash the BCM with exact GM specifications for your 2010 Yukon XL 1500.
- Disconnect the battery to ensure safety and prevent electrical shorts during the process.
- Locate the BCM under the steering column, remove the old unit by unplugging connectors and unbolting it carefully.
- Install the new BCM in the same position, reconnect all wiring harnesses securely, and reattach the battery.
- Perform any necessary relearns: If a no-start occurs post-install (rare with pre-programming), cycle the key from off to on three times, waiting 10 seconds each, to initiate theft deterrent relearn per GM standards.
- Test all functions, including lights, locks, and accessories, to confirm full operation.
