We flash it with the latest GM updates using your VIN for seamless integration, ensuring it matches your exact vehicle specs. This unit replaces part numbers like 15948439, 10382479, 15093910, and others, fitting models such as the Impala (LH dash), Equinox 07-09 (center dash), and Tahoe 10 (under steering column, ID 25892622).

Common Issues & How This Fixes Them
Owners of 2006-2013 Chevrolet Impalas frequently encounter BCM-related problems that can turn a smooth drive into a nightmare. One prevalent issue is erratic door lock operation, often caused by internal module corrosion from moisture ingress, leading to locks that engage randomly or fail entirely—think trying to secure your car in a busy parking lot only for the system to ignore your key fob. This replacement BCM resolves it by providing a sealed, updated unit that stabilizes communication between the locks and the central system. Another common headache is dashboard warning lights staying illuminated, tied to DTC B1370 or U0140, which signal lost communication with other modules; in scenarios like cold starts, this might prevent the engine from turning over, mimicking a dead battery. Installing this programmed BCM clears these codes by re-establishing robust data links, drawing from my experience where similar fixes have saved customers hundreds in unnecessary wiring repairs. Additionally, power window failures—windows that won’t roll up during rain—stem from degraded BCM relays; our VIN-matched module restores precise control, preventing water damage inside the cabin. For Impala drivers towing trailers, flickering exterior lights due to overloaded circuits can pose safety risks; this BCM’s enhanced processing handles the load better, ensuring consistent performance. Always check for related fuses first, as I’ve seen overlooked blown ones compound the problem, but swapping to this unit often provides the definitive fix without deeper disassembly.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your 2006-2013 Impala.
- Disconnect the battery to ensure safety and reset any residual power in the system—wait at least 10 minutes to avoid shocks.
- Locate the BCM on the left-hand side of the dash in your Impala; remove any panels or brackets securing it, using a trim tool to prevent scratches.
- Unplug the old module’s connectors carefully, noting their positions, then install the new BCM by reversing the process and securing it firmly.
- Reconnect the battery and perform a theft deterrent relearn if a no-start occurs: Insert the key, turn to ON for 10 minutes, off for 30 seconds, and repeat three times until the security light extinguishes.
- Test all functions like lights, locks, and windows; clear any lingering DTCs with an OBD-II scanner for optimal results.
