Restore Full Functionality to Your Saturn Outlook
If you’re dealing with baffling electrical issues in your 2007-2010 Saturn Outlook—like power windows with a mind of their own, flickering dash lights, or a security system that prevents your car from starting—you’ve likely met the culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, when the BCM falters, it can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
This replacement Body Control Module is the definitive, hassle-free solution. We take the guesswork and extra expense out of the repair by programming the module to your vehicle’s specific VIN before we ship it. It arrives at your door with the latest GM software updates, ready for installation. You get a reliable part that restores your vehicle’s electronics to perfect working order without a mandatory, costly trip to the dealership for programming.
Case Study: A Tricky Diagnosis
Just last month, a 2008 Saturn Outlook was towed to my shop. The owner was at his wit’s end. The interior lights would stay on, the radio would randomly shut off, and worst of all, the vehicle would intermittently refuse to start, with the security light flashing on the dash. He had already replaced the battery and checked the alternator. After connecting my scan tool, I saw a slew of ‘U’ codes, specifically a U0140 – Lost Communication With Body Control Module. This pointed directly to the BCM as the source of the network failure. Instead of a complex wiring chase, we confirmed the BCM was the faulty component. By installing a VIN-programmed module like this one, we had all the electrical systems communicating correctly and the vehicle running reliably in under an hour. It’s a common failure point I’ve seen on hundreds of these GM platforms.
Is Your Saturn Outlook Showing These Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system light is illuminated, and the engine won’t crank.
- ✔ The horn sounds randomly or doesn’t work at all.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.
- ✔ Wipers behaving erratically or not parking in the correct position.
Your Straightforward BCM Installation Guide
Installing your new 2007-2010 Outlook BCM is a manageable job for a confident DIYer. For the Saturn Outlook, the BCM is typically located in the center dash area, often accessible by removing the glove box or a lower dash panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to allow all systems to power down completely.
- Locate the BCM: Access the BCM, which is located in the center dash area. You may need to remove trim panels or the glove box for clear access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed to be released. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Power: Reconnect the negative battery terminal.
- Perform Final Steps: After installation, some critical relearn procedures are necessary. Follow the post-installation steps below for full system functionality.
Important Post-Installation Procedures
After replacing your BCM, a few final steps are required to ensure all vehicle systems operate correctly and safely. These procedures synchronize the new module with your vehicle’s other computers.
- Airbag System Reset: The airbag warning light will likely be on. You must perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible high-level scan tool. This is a critical safety step to ensure the airbag system is operational.
- Brake Pedal Position Sensor Relearn: Some vehicles require the Brake Pedal Position Sensor to be recalibrated after a BCM replacement. This ensures features like cruise control and brake lights function correctly.
- Consult Your Manual: While these are the most common procedures, specific requirements can vary. Always refer to a service manual for your exact vehicle or consult a professional if you are uncertain.

Frequently Asked Questions
Do I need to get this 2007-2010 Outlook BCM programmed by a dealer?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive with the latest GM software, ready for installation.
Where is the BCM located on a 2008 Saturn Outlook?
The Body Control Module on a 2007-2010 Saturn Outlook is typically located behind the dashboard on the passenger side, often accessible by removing the glove compartment.
What happens if I install this without doing the airbag or brake relearn procedures?
If you skip these steps, you will have a persistent airbag warning light on your dash, and the supplemental restraint system (SRS) may not function correctly in an accident. The brake lights or cruise control might also not work properly. These procedures are essential for safety and full functionality.
Will this fix my car’s security system issue that’s preventing it from starting?
Yes, in most cases. A faulty BCM is a very common cause of security system-related no-start conditions on these GM vehicles. This pre-programmed module is designed to resolve that communication failure.
Is this a used part?
This is a high-quality, inspected, and tested recycled OEM part, which is then programmed with fresh, VIN-specific software from GM. This ensures OEM-level reliability and perfect integration with your vehicle.
