2009 – 2012 Chevrolet TRAVERSE Body Control Module (BCM) 15921353 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with frustrating electrical glitches in your 2009-2012 Chevrolet Traverse, like doors that won’t lock properly or headlights flickering unexpectedly? You’re not alone—I’ve seen countless owners pull into the shop with these issues, often tracing back to a faulty Body Control Module (BCM). Questions like “why is my Traverse BCM causing dashboard warning lights?” or “how to resolve intermittent wiper failures in a 2010 Traverse?” pop up frequently in forums and voice searches. This pre-programmed BCM, part number 15921353, is your direct solution, flashed with the latest GM updates using your VIN for seamless integration. It clears persistent DTC codes related to body electronics and restores smooth operation, enhancing overall vehicle reliability. Compatible with a wide range of GM models, including Equinox 07-09, Impala 06-12, Acadia 07-12, and more—such as Tahoe 10 with ID 25892622 or Enclave 08-12—it fits Traverse models specifically at the LH dash location. Drawing from over two decades in diagnostics, I’ve witnessed how a failing BCM disrupts everything from power accessories to security systems, especially in harsh winter conditions where moisture infiltrates and corrodes connections. Replacing it not only fixes these but also improves towing reliability by stabilizing electrical loads, preventing unexpected shutdowns during heavy hauls. This unit arrives ready-to-install, programmed to match your exact vehicle specs, saving you hours of hassle and potential dealer fees.

Common Issues & How This Fixes Them

In my experience repairing GM vehicles, BCM failures in a 2009-2012 Chevrolet Traverse often manifest as erratic power windows that roll down on their own or fail to respond—typically due to internal circuit degradation from heat cycles or voltage spikes. Another common headache is dashboard lights illuminating without reason, like the security or ABS warnings, stemming from corrupted software that this pre-programmed module directly addresses by refreshing the firmware. Owners frequently ask, “what causes no-start issues in my Traverse after rain?”—it’s often water intrusion shorting the BCM, leading to communication breakdowns with the ECM. This replacement resolves that by providing a sealed, updated unit that clears related DTC codes and prevents future moisture-related faults. For towing enthusiasts, a bad BCM might cause trailer light malfunctions, risking safety on the road; our module stabilizes these connections for reliable performance. I’ve analyzed cases where ignoring early symptoms led to broader electrical failures, costing hundreds in diagnostics—swapping to this BCM not only fixes the root cause but also improves fuel efficiency by optimizing accessory power draw. In one shop anecdote, a client’s Traverse had intermittent horn issues during city driving; post-replacement, everything synced perfectly, demonstrating how it restores seamless integration across body systems.

Easy Installation Guide

1. Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your 2009-2012 Traverse.
2. Disconnect the battery to ensure safety and prevent electrical surges—locate the BCM at the LH dash area.
3. Remove the old module by unplugging connectors and unbolting it; compare part numbers to confirm compatibility.
4. Install the new BCM securely, reconnect all wiring, and reconnect the battery.
5. Perform post-install checks: If a no-start occurs, initiate theft relearn by cycling the key from off to run (without starting) 3 times for 10 minutes each—only needed if anti-theft triggers.
6. Reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool; some models may need brake pedal recalibration for optimal safety—consult your manual or a pro if unsure.
