Restore Your Traverse’s Performance and Reliability
Is your 2010-2012 Chevrolet Traverse experiencing frustrating issues like stalling, refusing to start, or a persistent Check Engine light? Before you consider replacing the entire fuel pump, the problem often lies with a much simpler component: the Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen countless vehicle owners and even professional shops misdiagnose these symptoms. The FSCM is the brain that tells the fuel pump how much pressure to deliver. When it fails, your engine is starved of fuel, leading to poor performance and stranding you at the worst possible times.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and dealer-dependency out of the repair. Each 2010-2012 Traverse FSCM is professionally programmed with the latest GM software updates specifically to your vehicle’s VIN. This means no expensive trips to the dealership for programming—it arrives at your door ready for a plug-and-play installation, restoring your vehicle’s fuel delivery to factory specifications.
Case Study: The Misdiagnosed Fuel Pump
A customer brought in their 2011 Traverse that would crank but not start intermittently. They had already spent a significant amount of money having a new fuel pump installed at another shop, but the problem persisted. A quick scan with my diagnostic tool revealed code U0109 – Lost Communication With Fuel Pump Control Module. On these Traverse, Acadia, and Enclave models, the FSCM is mounted on the rear crossmember, exposed to water, salt, and road debris. Corrosion had compromised the module’s internal circuits. We installed one of our VIN-programmed FSCMs, and the vehicle started right up and ran perfectly. This is a classic example of how replacing the FSCM first can save you hundreds of dollars and a lot of headaches.
Is Your Traverse Showing These FSCM Failure Signs?
A failing FSCM can mimic a bad fuel pump. Watch for these common indicators before making a costly repair decision. If you’re experiencing one or more of these, this module is very likely your solution.
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, especially under load
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ An active Check Engine Light with fuel-related diagnostic trouble codes (DTCs) such as P069E, P0230, or U0109
A Straightforward Guide to Installation
Replacing the FSCM on your Traverse is a job most DIY enthusiasts can handle in their own driveway. Located on the rear crossmember, it’s typically held in by just a few bolts. Follow these general steps to get your vehicle back in top shape.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: Safely raise the rear of the vehicle. You will find the FSCM mounted to the rear crossmember, near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connector. Be gentle to avoid breaking the locking tab. Then, remove the bolts securing the old module to the frame.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location. Secure it with the original bolts.
- Final Connections: Plug the electrical connector firmly into the new module until it clicks. Reconnect the negative battery terminal.
- Start and Verify: Start the engine. It may take a moment to prime the fuel system. Once running, your Check Engine light should be off and the symptoms resolved.

Frequently Asked Questions
Do I need to program this module?
No. This is the biggest benefit of our service. We program the module to your vehicle’s specific VIN before shipping it to you. It arrives ready to install, saving you a trip to the dealer.
What information do you need from me?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Where is this module located on my 2011 Traverse?
The FSCM on a 2010-2012 Traverse is mounted externally on the rear crossmember of the vehicle’s frame, typically near the spare tire area.
Will this fix a check engine code like P069E?
Yes, in most cases. Code P069E (Fuel Pump Control Module Requested MIL Illumination) directly points to a fault within the FSCM. Replacing the module is the standard, correct repair for this code.
Is this the same as the fuel pump?
No. The fuel pump is located inside your fuel tank. This Fuel System Control Module (FSCM) is a separate computer that controls the fuel pump. It’s often the actual point of failure and is much easier and less expensive to replace.
