Restore Full Functionality to Your Saturn Outlook
Are you dealing with baffling electrical issues in your 2007-2010 Saturn Outlook? Flickering lights, unresponsive power windows, a temperamental security system, or even a vehicle that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can turn your reliable SUV into a source of daily frustration. This isn’t just an inconvenience; it can affect safety systems and leave you stranded. I’ve seen it hundreds of times in the shop—what seems like multiple, unrelated problems are often solved with a single, targeted replacement.
This is your direct-fit, permanent solution. We offer a replacement Body Control Module, part number 15872388, that arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We load it with the latest, most stable software updates directly from GM. This means you can bypass the expensive dealership visit and the hassle of finding a shop with the right programming equipment. It’s the most efficient way to get your Outlook back to factory-spec operation.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Interior or exterior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ The key fob is no longer recognized by the vehicle.
- ✔ False warnings appearing on the instrument cluster (e.g., “Service Airbag,” “Service StabiliTrak”).
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, or other U-series codes.
- ✔ Wipers or the horn activating randomly.
A Technician’s Notebook: The Outlook with a Mind of Its Own
A customer brought in a 2009 Saturn Outlook that was driving them crazy. The radio would randomly shut off, the driver’s side window wouldn’t roll down, and occasionally the anti-theft light would flash, causing a no-start. They had already replaced the battery and checked fuses. My initial scan showed a dozen communication codes pointing in different directions. Instead of chasing ghosts, I went straight to the BCM. After connecting my scope, I found a noisy and unstable voltage signal on one of the BCM’s internal circuits. This instability was the root cause, sending corrupt data across the vehicle’s network. Installing a new, VIN-programmed BCM like this one solved every single issue instantly. It’s a classic case where one part failure mimics many.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to discharge.
- ✔ Locate the BCM: On the 2007-2010 Saturn Outlook, the BCM is typically located in the center dash area, often accessible by removing the lower dash panels or the glove box. Consult a service manual for the exact position.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM into the bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions—windows, locks, lights, and wipers—to confirm operation.
Important Post-Installation Steps
Because this BCM is pre-programmed, it simplifies the process significantly. However, depending on your vehicle’s specific configuration, a couple of final integration steps, known as ‘relearn procedures,’ may be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper function of the brake lights and stability control system.

Frequently Asked Questions
Why do you need my VIN to program the BCM?
Your vehicle’s VIN allows us to load the exact software and settings your Outlook was built with. This includes information about its specific features like keyless entry, lighting options, and security systems, ensuring seamless integration and proper function without a trip to the dealer.
Is this a difficult part for a DIYer to replace?
For most DIYers with basic tools, this is a very manageable job. The primary challenge is accessing the BCM’s location within the dash. Since our module comes pre-programmed, you eliminate the most difficult step, which is the software installation.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, faulty BCM back to us. This saves you the time and expense of return shipping and eliminates the need for a core deposit.
Will this BCM fix my check engine light?
A BCM typically controls body functions, not engine performance. If you have a check engine light, the issue is more likely related to the Engine Control Module (ECM) or a powertrain sensor. A BCM failure is more likely to cause security lights, airbag lights, or communication codes (U-codes).
What if my airbag light comes on after I install it?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to the airbag’s Supplemental Deployment Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure with a bidirectional scan tool, which any professional mechanic can perform quickly.
