2008 – 2012 GMC SAVANA 3500 Body Control Module (BCM) 15828601 – Programmed to Your VIN
Ever dealt with erratic dashboard lights or doors that refuse to lock on your 2008-2012 GMC Savana 3500 during a long haul? These frustrating symptoms often point to a failing Body Control Module (BCM), the central hub managing everything from power windows to anti-theft systems. Imagine towing heavy loads in tough weather, only to have wipers glitch out mid-storm—it’s not just inconvenient; it compromises safety. Our pre-programmed BCM, part number 15828601, arrives flashed with the latest GM updates tailored to your VIN, ensuring seamless integration. This isn’t a generic swap; it’s a precise match that restores reliable performance, clearing common DTCs like U0140 or B1370 that plague these vans. Compatible with a range of GM models including Express 3500, Tahoe, and Yukon variants, it supports part numbers like 10382479, 20815898, and 25892622. By addressing root causes like water intrusion or voltage spikes, this module delivers peace of mind for fleet owners and DIY mechanics alike, drawing from real-world fixes I’ve seen in over two decades of shop work.

Common Issues & How This Fixes Them
Owners of 2008-2012 GMC Savana 3500 vans frequently report issues like non-responsive power locks, flickering interior lights, or even a no-start condition tied to the theft deterrent system—often after exposure to moisture from leaky seals. In my experience, these stem from BCM corrosion or internal circuit failures, exacerbated by heavy-duty use in commercial settings. For instance, if you’re hauling cargo and notice DTC U0100 (lost communication with ECM), it’s likely the BCM disrupting data flow, leading to rough idling or stalled engines. Another common headache is B1370 for ignition key faults, causing security lights to stay on and preventing startup, especially in cold weather starts. This programmed BCM fixes these by restoring proper module communication, using updated firmware to bypass outdated glitches. I’ve seen vans where replacing the BCM cleared persistent airbag warnings without needing full system overhauls. For Savana models with the 6.6L diesel (VIN 6, opt LMM), it tackles fuel pump relay issues that mimic low battery symptoms. Pro tip: Scan for codes before replacement to confirm—tools like an OBD-II reader can pinpoint if the BCM is the culprit, saving you from chasing unrelated wiring problems. This approach not only resolves symptoms but prevents cascading failures, like when a bad BCM drains the battery overnight.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates for your specific 2008-2012 Savana 3500.
- Disconnect the battery to ensure safety and prevent electrical shorts during the swap—locate the BCM in the center dash area.
- Remove the old module by unplugging connectors and unbolting it; compare part numbers to verify compatibility with options like 15828601 or 25892622.
- Install the new BCM securely, reconnect all wiring harnesses, and reconnect the battery.
- Perform necessary relearns: If a no-start occurs due to theft deterrent, cycle the key from off to on (without cranking) for 10 minutes, repeat three times. Reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool. For some vans, recalibrate the brake pedal to optimize braking—consult your manual or a tech if unsure.
- Test all functions like lights, locks, and accessories; clear any remaining DTCs with a scan tool for full functionality.
