Is Your Chevrolet Monte Carlo or Impala Experiencing Electrical Gremlins?
If your 2000-2004 Monte Carlo or Impala is suffering from strange and unpredictable electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and locks to the interior lights and security system. When it fails, it can create a host of frustrating problems that seem to have no rhyme or reason.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system acting up, preventing the car from starting (Passlock issues).
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ Radio or climate control malfunctions.
- ✔ False warning lights appearing on the dashboard.

Installation and Post-Install Notes
Installation is typically straightforward, as the BCM is located under the driver’s side of the dashboard. However, after installing the new module, a couple of procedures may be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system’s sensing and diagnostic module (SDM) and must be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and traction control functionality.
Best of all, there is no core charge for this part. You can keep your old module without the hassle of shipping it back.
Frequently Asked Questions
What does the Body Control Module do on my 2002 Monte Carlo?
The BCM controls a wide array of your car’s electronic accessories. This includes power windows, locks, interior lighting, the security system (Passlock), warning chimes, and communication between other modules.
Do I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we program the module to your car’s specific VIN before we ship it. This makes the installation process much simpler and saves you the cost and time of a dealership visit.
Where is the BCM located?
On 2000-2004 Monte Carlo and Impala models, the BCM is typically located on the driver’s side, up under the dashboard near the steering column.
What is a VIN and why do you need it?
The VIN is your car’s unique 17-digit identification number. We use it to load the correct software and vehicle-specific options into the BCM, ensuring it works perfectly with your car’s features right out of the box.
What if the airbag light comes on after I install it?
This can happen because the new BCM needs to be electronically ‘introduced’ to the airbag system module. A technician with a high-end diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this part compatible with part number 10340320?
Yes, this module (10350647) is a fully compatible and updated replacement for several service numbers, including 10340320.
