Is Your Chevrolet Impala Experiencing Strange Electrical Issues?
If your vehicle’s lights are flickering, power windows are acting erratically, or the security system is malfunctioning, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central computer responsible for managing your car’s non-engine-related functions, from the interior lights and power locks to the instrument cluster and climate controls. When it begins to fail, it can cause a cascade of frustrating and unpredictable problems that can make your vehicle feel unreliable.
From the Diagnostic Bay
We had a 2011 Impala come into the shop with a classic case of BCM failure. The customer reported that their turn signals would sometimes work and sometimes not, the radio would shut off randomly, and the ‘Service Theft System’ message kept appearing on the dash. After running diagnostics, we confirmed communication errors with the BCM. Swapping in a pre-programmed module like this one resolved all the issues instantly. The customer was thrilled to have their car back to normal without a costly trip to the dealership.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Instrument panel gauges behaving erratically or going dark.
- ✔ Intermittent issues with the radio or climate control systems.
- ✔ A ‘Service Theft System’ or similar warning message on the dashboard.
- ✔ Unexplained battery drain when the vehicle is turned off.

Installation and Post-Install Procedures
Installation is typically straightforward, involving disconnecting the battery, locating the old BCM (often under the driver’s side dash), swapping the connectors to the new module, and reconnecting the battery. However, on some GM vehicles, additional steps may be required after the physical installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic accessories not related to the engine. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and instrument panel functions.
Do I need to program this module?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during or after checkout, and the BCM will arrive loaded with the latest GM software specific to your car, ready for installation.
How do I find my current BCM’s part number?
The part number is printed on a sticker on the BCM itself. You will need to locate the module in your vehicle (typically under the dashboard on the driver’s side) to read the number directly from the unit.
What if the airbag light comes on after I install the BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A mechanic with a professional-grade diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge or do I need to return my old part?
There is no core charge for this module. You can keep your original part.
