2009 – 2012 Chevrolet Traverse Body Control Module (BCM) 15948439 – Programmed to Your VIN
Imagine pulling into your driveway after a long day, only to find your 2009-2012 Chevrolet Traverse refusing to unlock the doors or start the engine—classic signs of a failing Body Control Module. If you’re dealing with erratic lights, unresponsive power accessories, or mysterious dashboard warnings, this pre-programmed BCM (part number 15948439) could be your straightforward solution. It’s flashed with the latest GM updates directly matched to your VIN, ensuring seamless integration without compatibility headaches. This module replaces a wide array of OEM numbers, including 10382479, 15093910, and others up to 95151084, and fits various GM models like the Acadia, Equinox, and Express vans. Drawing from over two decades in diagnostics, I’ve seen how a faulty BCM disrupts everything from climate control to security systems in these crossovers. By opting for this VIN-specific unit, you restore reliable operation, potentially clearing nagging DTCs like B1325 or U0140 that plague Traverse owners during cold starts or humid weather.

Common Issues & How This Fixes Them
Owners of 2009-2012 Chevrolet Traverse models often encounter BCM-related headaches that stem from moisture intrusion, voltage spikes, or age-related wear. For instance, if your interior lights flicker or fail to respond, it might trace back to a corrupted module causing communication errors—think DTC B1370 popping up on your scanner. In rainy conditions, I’ve helped clients troubleshoot door lock malfunctions where the BCM loses sync with the key fob, leading to security lockouts. Another frequent complaint is erratic window operation or HVAC blower inconsistencies, often linked to DTC U0101, which disrupts the module’s control over body functions. This programmed BCM tackles these by resetting the system’s baseline with updated firmware, effectively clearing those codes and restoring smooth performance. Consider a real scenario: a Traverse owner towing a trailer noticed dash lights dimming erratically; replacing the BCM stabilized the electrical load, preventing further breakdowns. Expert tip—always check battery voltage first, as low power can mimic module failure. By addressing root causes like these, you avoid costly dealer visits and gain peace of mind for everyday use.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your Traverse.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap—locate the BCM on the left-hand dash side.
- Remove the old module by unplugging connectors and unbolting it carefully, noting any wire positions for reference.
- Install the new BCM in the same spot, reconnecting all harnesses securely to avoid loose connections that could trigger faults.
- Reconnect the battery and perform a basic system check; if a no-start issue arises post-install, initiate the theft deterrent relearn.
- For relearn: Insert key, turn to ON for 10 minutes (engine off), then off for 5 seconds—repeat three times or until the security light extinguishes, per GM standards. No relearn needed unless symptoms persist.
