Ever dealt with erratic door locks or dashboard lights flickering on your 2006-2013 Chevrolet Impala during a rainy commute? These frustrating symptoms often point to a failing Body Control Module (BCM), disrupting everything from power windows to security systems. As a seasoned automotive advisor with decades in diagnostics, I’ve seen countless Impala owners struggle with these issues, especially in older models exposed to moisture or electrical shorts. Our solution? This pre-programmed BCM, part number 20815898, flashed with the latest GM updates using your VIN for a perfect match. It replaces a wide array of compatible numbers like 10382479, 15093910, and more, ensuring seamless integration across various GM vehicles.

Common Issues & How This Fixes Them
In my experience troubleshooting GM vehicles, a faulty BCM in a 2006-2013 Impala often manifests as intermittent power door lock failures—imagine trying to secure your car in a busy parking lot, only for the locks to ignore your key fob. This stems from degraded internal circuits, exacerbated by age or water intrusion, leading to communication breakdowns with other modules. Another common headache is dashboard warning lights staying on, like the security light, which can trigger no-start conditions due to anti-theft system glitches. We’ve seen DTCs such as B1370 (Device Ignition Circuit) or U0140 (Lost Communication with BCM) pop up frequently in these models, halting drives and requiring scans.
Replacing with this programmed BCM resolves these by restoring proper signal relay and module handshakes. For instance, it fixes DTC B1370 on Impala by recalibrating ignition controls, preventing random stalls during city driving. Electrical gremlins, like non-functional interior lights or erratic wipers, vanish as the new unit manages power distribution more reliably. I’ve advised owners facing “how to fix BCM issues on 2006-2013 Impala” queries to check for corroded connectors first—a quick visual inspection can reveal causes like harness wear from engine bay heat. This replacement not only clears codes but also prevents recurrence, drawing from GM’s updated firmware to handle modern demands like integrated infotainment. In towing scenarios with an Impala, a stable BCM ensures trailer lights work flawlessly, avoiding roadside hassles.
Easy Installation Guide

- Locate the BCM on the left-hand dash (LH dash) in your 2006-2013 Impala; remove any panels carefully to access it.
- Unplug the old module, connect the new one, and secure it in place—double-check all connections for a snug fit.
- Reconnect the battery and perform a theft deterrent relearn if a no-start occurs: Insert key, turn to ON for 10 minutes (three cycles if needed), then start the engine.
- After installation, reset the airbag warning light by performing the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool; recalibrate the brake pedal if required for optimal safety, consulting your manual or a pro for vehicle-specific variations.
