2003 – 2007 GM Sierra 2500 Body Control Module 15137395 Programmed To Your VIN

2003 – 2007 GMC SIERRA 2500 BCM (BCM) 15137395 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with your GMC Sierra 2500’s lights flickering unpredictably during a late-night haul, or wondered why the power locks fail right when you’re loading up for a job site? These frustrating glitches often trace back to a faulty Body Control Module (BCM), disrupting everything from interior electronics to security systems in 2003-2007 models. As a seasoned mechanic who’s diagnosed countless trucks like yours, I’ve seen how a failing BCM can throw DTC codes like U0140 or trigger no-start conditions, especially in heavy-duty setups used for towing. The good news? Our pre-programmed BCM, part number 15137395, arrives ready to install with the latest GM software updates matched to your VIN—clearing those persistent error codes and restoring smooth operation. It fits seamlessly with interchangeable numbers like 10383536, 15116066, and others, ensuring compatibility across various GM trucks and SUVs. This isn’t just a replacement; it’s a reliable fix that enhances overall vehicle reliability, from better electrical stability during off-road adventures to improved response in daily driving. By addressing root causes like corrosion or software glitches, you’ll avoid costly downtime and regain confidence on the road.

Common Issues & How This Fixes Them

In my two decades fixing GM trucks, BCM failures in 2003-2007 Sierra 2500 models often show up as erratic behavior in body functions. For instance, you might notice intermittent power window failures or dome lights that won’t turn off, draining your battery overnight—common in trucks exposed to harsh weather or frequent towing. These stem from internal circuit degradation or moisture ingress, leading to communication errors with other modules. Another frequent headache: security system malfunctions causing anti-theft lockouts, where the key fob refuses to respond, stranding you at the worst times. We’ve seen this in crew cab variants hauling heavy loads, where vibrations accelerate wear.

Replacing with our VIN-programmed BCM resolves these by integrating fresh GM calibrations that clear DTC codes like B1370 and restore module synchronization. Picture a real scenario: A client with a 2005 Sierra 2500 reported random horn activations during rain; after swapping the BCM, it not only fixed the issue but also improved towing reliability by stabilizing trailer light connections. For vans like the Savana with commercial packages, it eliminates dashboard glitches tied to the PRP option. Expert tip: Scan for codes before replacement to pinpoint if the BCM is the culprit—often, it’s linked to under-steering-column mounting where dirt accumulates. This approach prevents misdiagnosis and ensures long-term fixes, saving you from repeated shop visits.

4. Install the new BCM, reconnecting all harnesses securely, then reconnect the battery.
5. Perform a theft relearn if no-start occurs: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times—only needed if security issues persist.
6. Reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure using a diagnostic tool; recalibrate brake pedals if your model requires it for optimal safety.
