Restore Peak Performance to Your Chevrolet Traverse
Is your 2010-2012 Chevrolet Traverse experiencing frustrating issues like stalling, hesitation during acceleration, or a complete no-start condition? Before you suspect the fuel pump itself, the culprit is often its electronic brain: the Fuel System Control Module (FSCM). As a technician with over two decades of diagnostic experience, I’ve seen countless vehicles sidelined by a faulty FSCM. This module is critical for regulating the voltage sent to your fuel pump, ensuring your engine receives the precise amount of fuel it needs under all driving conditions. When it fails, it can cause a wide range of perplexing and potentially dangerous drivability problems.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and high cost out of the repair by programming this 2010-2012 Traverse FSCM to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means no expensive trip to the dealership for programming. You get a module loaded with the latest GM software updates, ensuring optimal performance and compatibility right out of the box. It’s the most efficient way to get your Traverse back on the road with confidence.
A Technician’s Notebook
I remember a 2011 Traverse that came into the shop on a tow truck. The owner had already replaced the fuel pump, but the vehicle still wouldn’t start. It had a U0109 code—Lost Communication with Fuel Pump Control Module. A quick check under the vehicle revealed the problem. The FSCM on these Lambda-platform SUVs (Traverse, Acadia, Enclave) is mounted on the rear crossmember, directly in the line of fire for road salt and moisture. The original module’s casing was swollen and the connectors were green with corrosion. This is a failure I’ve diagnosed hundreds of times. A new, pre-programmed module had the vehicle running perfectly in under 30 minutes, saving the customer from further incorrect and expensive repairs.
Is Your Traverse Exhibiting These Fuel Issues?
A failing FSCM can mimic other component failures. If you’re experiencing any of the following, this module is a likely cause:
- ✔ Engine cranks but will not start
- ✔ Stalling, especially under load or when coming to a stop
- ✔ Rough idle or engine hesitation
- ✔ Reduced engine power and poor acceleration
- ✔ Check Engine Light (CEL) with specific trouble codes
- ✔ Common Diagnostic Trouble Codes (DTCs): U0109, P069E, P0230, P025A
A Straightforward Guide to Installation
Replacing the FSCM on your Traverse is a job most DIYers can handle with basic tools. Our pre-programmed module makes it a simple plug-and-play process.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On the 2010-2012 Traverse, the FSCM is typically mounted to the rear subframe/crossmember, accessible from underneath the vehicle.
- Disconnect Electrical Connectors: Carefully press the release tabs and pull the two electrical connectors straight out from the old module. Inspect the harness connectors for any corrosion or damage.
- Remove Mounting Bolts: Unbolt the old module from the frame. These are usually two small bolts (often 10mm).
- Install the New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original bolts.
- Reconnect and Secure: Plug the electrical connectors firmly into the new module until they click into place. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘On’ position for a few seconds to allow the system to prime, then start the engine. The vehicle should now run smoothly.

Frequently Asked Questions
What does VIN programming do?
VIN programming loads your vehicle’s specific software and calibrations onto the module. This ensures it communicates perfectly with your car’s other computers, like the ECM and BCM, for proper fuel delivery and engine function. It eliminates the need for a dealer visit.
Is this a difficult part to install myself?
No, this is a great DIY-friendly repair. Because we program the module for you, installation is a simple ‘unplug and replace’ process that typically takes less than an hour with basic hand tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for the part to function.
Will this fix a U0109 trouble code?
Yes, in the vast majority of cases. The U0109 code means the Engine Control Module (ECM) has lost communication with the FSCM. This is most commonly caused by an internal failure of the FSCM itself, making this part the direct solution.
Is this a new or used part?
This is a high-quality, tested recycled OEM part. It is guaranteed to function correctly and is backed by our warranty. We program it with the newest software from GM, ensuring it performs reliably.
