2008 – 2012 GM Savana 3500 Body Control Module 15093910 Programmed To Your VIN

2008 – 2012 GMC Savana 3500 Body Control Module (BCM) 15093910 – Programmed to Your VIN

Imagine hauling a heavy load in your 2008-2012 GMC Savana 3500 when suddenly the headlights flicker, the doors won’t lock, or your dashboard lights up with warning codes—frustrating issues that can sideline your work van. As a seasoned automotive advisor who’s diagnosed countless electrical glitches in GM vans, I’ve seen how a faulty Body Control Module (BCM) often lies at the heart of these problems. This pre-programmed BCM, part number 15093910, arrives flashed with the latest GM updates tailored to your VIN, ensuring seamless integration. It replaces a wide array of OEM numbers like 10382479, 15276271, and 25892622, fitting not just your Savana 3500 but also models such as the Express 3500 Van and Tahoe from similar years. By addressing root causes like communication failures, this module restores reliable operation, preventing downtime and costly towing. You’ll notice smoother electrical functions right away, from power windows to anti-theft systems, all backed by precise VIN matching for optimal performance.

Common Issues & How This Fixes Them

Owners of 2008-2012 GMC Savana 3500 vans often face BCM-related headaches that disrupt daily use. One frequent problem is erratic interior lighting or power accessories failing, typically caused by corroded connectors or internal module degradation from moisture exposure—common in work vans parked outdoors. This can trigger DTCs like U0140 for lost communication with other modules, leaving you stranded with non-functional doors or windows during a job. Another issue involves no-start conditions tied to the theft deterrent system, where the BCM fails to recognize the key, often after battery replacements or electrical shorts. In my experience, hauling in wet weather exacerbates these, as water ingress accelerates failure. Replacing with this programmed BCM resolves them by restoring proper signal processing and updating firmware to prevent recurrence. For instance, if you’re seeing DTC B1370 for ignition key issues, this unit clears it by recalibrating the immobilizer. Additionally, intermittent wiper or horn problems, linked to BCM relay faults, vanish post-install, improving safety. A tip: Always check harness connections first—I’ve saved clients hours by spotting loose wires mimicking module failure. This approach not only fixes symptoms but enhances long-term durability, especially for high-mileage vans.

Easy Installation Guide

1. Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates before shipping.
2. Disconnect the battery to ensure safety and prevent electrical surges during the swap—locate the BCM in the center dash area of your Savana 3500.
3. Remove the old module by unplugging connectors and unscrewing mounts; compare part numbers to confirm fit.
4. Install the new BCM, reconnecting all harnesses securely to avoid future communication errors.
5. Reconnect the battery and perform a system check—turn the key to ON for 10 minutes without starting to allow initial synchronization.
6. If a no-start occurs due to theft deterrent, initiate relearn: Insert key, turn to ON for 10 minutes until the security light goes off, then off for 5 seconds; repeat three times. No professional tools needed per GM standards.
