2008 – 2012 GMC Savana 1500 Body Control Module (BCM) 15948438 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your GMC Savana 1500’s lights flickering erratically during a rainy drive, or the power locks refusing to respond when you’re hauling cargo in cold weather? As a seasoned mechanic who’s seen countless 2008-2012 Savana vans roll into the shop with these frustrating symptoms, I know how a failing Body Control Module (BCM) can turn a reliable workhorse into a headache. Questions like “why won’t my Savana 1500 start after battery replacement” or “how to resolve BCM-related DTC codes in a 2010 GMC van” often point straight to this central component. Our pre-programmed BCM, part number 15948438, arrives flashed with the latest GM updates using your VIN for a seamless match. It tackles these issues head-on, restoring smooth operation of lights, wipers, security systems, and more. This isn’t just a swap—it’s a precision fix that clears persistent trouble codes and enhances overall electrical reliability, especially for towing or fleet use where downtime costs you money. Compatible with a wide range of GM models like Express vans, Tahoe, and Impala from similar years, it cross-references numbers such as 10382479, 15093910, and others for broad applicability.
Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, I’ve diagnosed BCM failures in Savana 1500s that manifest as intermittent electrical glitches—think dashboard warnings lighting up without reason or anti-theft systems locking you out. A common culprit? Corrosion from moisture exposure in vans used for delivery, triggering DTC codes like U0140 or B1370 that disrupt communication between modules. This leads to symptoms such as non-functional power windows, erratic horn behavior, or even reduced towing reliability when trailer lights fail to sync. Replacing with our VIN-programmed BCM resolves these by recalibrating the network, effectively clearing those codes and preventing recurrence. Another frequent issue: security system malfunctions causing no-start conditions, often after a dead battery. Our module integrates the newest GM firmware, bypassing outdated software bugs that exacerbate this in 2008-2012 models. For fleet owners, this means fewer roadside calls and improved safety during heavy loads. I’ve seen shops overlook simple checks like fuse integrity, but pairing this BCM with a quick scan tool reset transforms reliability—think smoother idling and consistent accessory performance, even in extreme temperatures.

Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with GM’s latest updates for your 2008-2012 Savana 1500—ensures perfect calibration right out of the box.
- Disconnect the battery to avoid electrical surges, then locate the BCM in the center dash area (common for Savana vans).
- Remove the old module by unplugging connectors and unbolting it—inspect for water damage, a frequent issue in these models.
- Install the new BCM, reconnect everything securely, and reconnect the battery.
- Perform any necessary relearns: For theft deterrent if no-start occurs, cycle the key from off to on (without starting) 10 times, waiting 10 minutes each—GM standard for these years. Also, recalibrate the brake pedal if your van requires it for optimal stopping power, and reset airbag warnings via the SDM setup with a scan tool.
- Test all functions like lights and locks; consult your manual or a pro if variations arise, as some setups need brake system verification for safety.
