2008 – 2013 GM – Body Control Module 15872421 Programmed To Your VIN

2008 – 2013 GM – Body Control Module (BCM) 15872421 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Imagine you’re behind the wheel of your 2010 Chevrolet Tahoe, ready for a family road trip, but suddenly the power windows refuse to budge, the door locks act up, and dashboard warning lights flicker like a bad horror movie. Sound familiar? If you’re dealing with erratic electrical issues in your 2008-2013 GM vehicle, like a Chevy Impala or GMC Yukon, a faulty Body Control Module (BCM) could be the culprit. Questions like “Why won’t my 2009 Chevy Equinox door locks work?” or “How to fix BCM failure in a 2012 GMC Savana van?” often lead owners here. This pre-programmed BCM, featuring part number 15872421 among compatibles like 25892622 and 20921435, arrives ready to install after we flash it with your VIN for the latest GM updates. It clears nagging DTC codes, restores seamless body functions, and boosts overall electrical reliability—think improved anti-theft response and consistent accessory operation, even during heavy towing in your Express 3500.

Common Issues & How This Fixes Them

Over my two decades in auto repair, I’ve seen countless GM owners frustrated by BCM woes in models from 2008 to 2013. One common headache is intermittent power accessory failures—windows, locks, or mirrors that work one day and quit the next. This often stems from internal module corrosion or voltage spikes, especially in humid climates or after battery issues, leading to DTC codes like U0140 or B1370. Replacing with our VIN-matched BCM resolves this by recalibrating communication networks, preventing those random shutdowns that strand you.

Another frequent problem hits vans like the Savana 2500: erratic lighting or wiper controls, caused by degraded circuitry overloading the module. I’ve diagnosed this in shop scenarios where a simple fuse check misses the root BCM fault, resulting in unsafe night driving. Our unit fixes it by integrating fresh GM firmware, which enhances signal processing and clears error codes for reliable performance.

Then there’s the no-start condition tied to security system glitches, common in Tahoes or Yukons. If the BCM loses sync with the immobilizer, your engine won’t turn over— a real pain during cold starts. This replacement restores harmony, often without full relearn if programmed correctly, improving startup reliability.

For luxury rides like the Cadillac DTS, airbag warning lights persist post-fault, signaling SDM mismatches. Our BCM addresses this directly, allowing proper resets to ensure safety features function as intended.

Easy Installation Guide

1. Provide your VIN after purchase so we can program the BCM with the latest GM updates tailored to your vehicle.
2. Disconnect the battery to ensure safety, then locate the BCM—typically under the steering column in Tahoes or center dash in Express vans.
3. Remove the old unit by unplugging connectors and unbolting it; install the new one in reverse, securing all connections firmly.
4. Reconnect the battery and perform initial power-up; if no-start occurs, initiate theft relearn by cycling the key from off to run (without cranking) 3-4 times for 10 minutes each, until the security light extinguishes.
5. Reset the airbag warning light using a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ procedure to align safety systems.
6. For some models, recalibrate the brake pedal to optimize braking response—consult your manual or a tech for vehicle-specific steps.
