Common Issues & How This Fixes Them
In my two decades fixing GM rides, BCM failures in 2006-2013 Chevrolet Impalas often manifest as mysterious electrical gremlins. For instance, you might notice headlights dimming unexpectedly or the horn blaring without reason—caused by corroded circuits or software glitches that overload the module. This can stem from moisture ingress during Midwest winters, leading to shorted connections and codes like B1370 or U0140 popping up on your scanner. Another common headache: power accessories like seats or mirrors going haywire, disrupting commutes and even safety if it affects lighting. I’ve diagnosed cases where a bad BCM mimicked alternator problems, wasting time on wrong fixes. Replacing with our pre-programmed 20864768 unit resolves these by restoring precise control over body functions, clearing DTC codes, and preventing voltage spikes that damage related components. It also improves towing reliability if you’re hauling with your Impala, ensuring stable trailer lights. One client reported their intermittent no-start vanished post-install, thanks to refreshed anti-theft protocols. For deeper insight, always scan for underlying causes like wiring harness wear before swapping— this proactive step avoids repeat issues and maximizes longevity.
Easy Installation Guide
- Provide your VIN 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 prevent electrical surges—wait 10 minutes before proceeding.
- Locate the BCM on the LH dash; remove any panels or brackets securing it, then unplug the connectors carefully.
- Install the new module in the same position, reconnect all harnesses securely, and reattach the battery.
- Perform necessary relearns: If a no-start occurs due to theft system, cycle the key from off to on (without starting) 3 times, waiting 10 minutes each—GM standard for BCM sync.
- Reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ with a diagnostic tool; recalibrate the brake pedal if your model requires it for optimal safety.
