Is Your Impala Acting Possessed? You’re Not Alone.
As a technician with over two decades of experience, I’ve seen it all. A 2011 Impala gets towed to the shop, battery dead again. The owner has already replaced the battery twice and the alternator once. The real problem? A failing Body Control Module (BCM) creating a parasitic draw that drains the battery overnight. Flickering interior lights, power windows with a mind of their own, a security light that won’t turn off—these are the classic, frustrating signs of a BCM on its last legs. Your Impala’s BCM is the central computer for all its comfort and convenience features, and when it fails, it can cause a cascade of baffling electrical issues.
This isn’t just a part; it’s the permanent solution to those electrical gremlins. We take a reliable, tested BCM and program it specifically to your vehicle’s VIN using the latest GM software updates. This means it arrives at your door ready for installation, saving you a costly trip to the dealership for programming.
The Simple Fix for Complex Electrical Problems
Don’t keep throwing parts at your car hoping to solve the issue. A faulty BCM is often the root cause. This module is the definitive repair for a wide range of symptoms:
- ✔ Intermittent or non-working power windows, locks, or mirrors.
- ✔ Flickering or inoperative interior and exterior lights.
- ✔ The dreaded “Service Theft System” message on the dash.
- ✔ Unexplained parasitic battery drain that leaves you stranded.
- ✔ Erratic behavior from your radio or climate control system.
- ✔ False warning lights on the instrument cluster.
Expert Pro Tip: Check Your Connections First
Before you condemn your BCM, take a moment to inspect the main electrical connectors going into the module. In my shop, I’ve seen cases where simple corrosion on the pins caused enough resistance to mimic a complete BCM failure. Unplug the connectors (with the battery disconnected!), spray them with a quality electronics cleaner, and use a small brush to gently clean the pins. It’s a five-minute check that could save you a lot of hassle.
Plug-and-Play Installation: No Dealer Visit Required
Installing your pre-programmed 2006–2013 Impala Body Control Module is a straightforward process you can do in your own garage. Because we handle the programming, you skip the most expensive and complicated step.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module and remove it.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Battery & Perform Relearns: Reconnect your battery terminal. This is a critical step: You will need to perform a few procedures with a capable scan tool. This includes the ‘Setup SDM Primary Key in BCM’ to clear any airbag faults and, in some cases, a ‘Brake Pedal Position Sensor Relearn’ to ensure proper brake light and stability control function. Failure to do these relearns can result in warning lights and system malfunctions.
