Are you battling frustrating electrical problems in your Saturn Outlook or other GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or a persistent ‘Service Theft System’ message on your dash often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of confusing and intermittent symptoms. This isn’t just an inconvenience; it can affect your vehicle’s security and daily usability.
This replacement Body Control Module is the definitive solution to restore your vehicle’s electronic functions to factory-new condition. We take the guesswork and hassle out of the repair process. Before we ship your part, we program it with the latest GM software updates, specifically matched to your vehicle’s unique VIN. This means no expensive trips to the dealership for programming—it’s a direct-fit, ready-to-install component designed to get you back on the road quickly and confidently.
From the Diagnostic Bay
We had a customer with a 2009 Chevy Traverse (which uses this exact BCM) who was ready to sell the car due to electrical gremlins. The radio would turn on by itself, the door locks would cycle randomly while driving, and the battery would be dead every few days. They had already replaced the battery and alternator. After a quick diagnostic scan, we saw multiple communication codes pointing to the BCM. We installed a VIN-programmed module, and it was like a new vehicle. All the strange issues vanished instantly. It’s amazing how this one module can be the source of so many headaches.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or interior/exterior lights.
- ✔ ‘Service Theft System’ or ‘Security’ warning lights on the instrument cluster.
- ✔ Erratic behavior from the radio or climate control system.
- ✔ A parasitic battery drain that kills your battery overnight.
- ✔ The remote keyless entry (fob) stops working reliably.
- ✔ False warnings for open doors or other system alerts.
- ✔ Diagnostic trouble codes (DTCs) related to U-codes or loss of communication.

Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What does the Body Control Module do?
The BCM is a computer that controls most of your vehicle’s non-engine related electronics. This includes power windows, locks, lights, wipers, security system, and instrument cluster functions.
Is this part difficult to install?
For someone with moderate DIY mechanical skill, the physical replacement is typically straightforward, often located under the dash. The key benefit of our module is that it comes pre-programmed, eliminating the most difficult step. However, some vehicles may require the post-installation procedures mentioned above.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will contact you for your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
My vehicle isn’t a Saturn Outlook, but my part number matches. Will this work?
Yes. This BCM fits a very wide range of GM vehicles, including models from Chevrolet, GMC, Cadillac, Buick, Pontiac, and Hummer. As long as your part number is on our cross-reference list, this module is the correct fit for your vehicle.
