Is Your Impala Acting Possessed?
If your 2006-2013 Chevrolet Impala is suffering from baffling electrical problems, you’re not alone. In my 20+ years as a technician, I’ve seen it all: dashboard lights flickering like a disco, power windows with a mind of their own, the security system preventing the car from starting, or the radio randomly turning on. These aren’t ghosts in the machine; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features, and when it goes bad, it can make your car incredibly frustrating to own.
A Technician’s Real-World Experience
“A customer’s 2011 Impala came into my shop last week with these exact symptoms. The security light was flashing, and it was a no-crank, no-start situation. He had already replaced the battery and checked the fuses. After connecting my scan tool, I saw a flood of communication error codes pointing directly to a faulty BCM. This isn’t an uncommon issue; water intrusion from a leaky cowl or simple internal electronic failure is a frequent cause on these models. Replacing the BCM solved every single one of his car’s issues.”
The Direct-Fit, No-Hassle Solution
This isn’t just a replacement part; it’s a complete solution. We take a genuine OEM BCM and program it with the latest GM software updates specifically for your vehicle’s VIN. This means you can skip the expensive trip to the dealership for programming. It arrives at your door ready for installation, saving you time, money, and headaches.
Common Symptoms of a Failing 2006-2013 Impala BCM:
- ✔ Intermittent or total failure of power windows, locks, or interior lights.
- ✔ The security or anti-theft light stays on or flashes, preventing the engine from starting.
- ✔ Erratic instrument cluster behavior, with gauges dropping out or warning lights appearing for no reason.
- ✔ The key fob stops working or works sporadically.
- ✔ Communication error codes (U-codes) stored in the vehicle’s computer system.
- ✔ Unpredictable battery drain when the vehicle is off.
Simple Installation Process
For the 2006-2013 Impala, the BCM is located on the left-hand (driver’s) side of the dashboard, typically behind the lower dash panel. While professional installation is always recommended, a skilled DIYer can perform this replacement.
- Safety First: Disconnect the negative terminal from your car’s battery and wait 10-15 minutes for the system capacitors to discharge.
- Access the Module: Carefully remove the lower dash panel below the steering wheel to expose the BCM.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Then, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in place and securely reconnect all electrical connectors.
- Reconnect Battery: Re-attach the negative battery terminal.
Important Post-Installation Steps
After installing your new BCM, a few final procedures are necessary to ensure full system functionality. This is critical for safety and performance.
- Airbag System (SRS): The airbag warning light will likely be on. You must perform the ‘Setup SDM Primary Key in BCM’ procedure using a bi-directional scan tool. This re-establishes communication between the new BCM and the airbag system.
- Brake Pedal Position Sensor: Some vehicles require a brake pedal position sensor relearn or recalibration. This ensures the brake lights and stability control system function correctly.
