Restore Power and Reliability to Your GM Vehicle
Is your 2010-2012 Cadillac Escalade ESV experiencing frustrating issues like stalling, hesitation, or a complete no-start condition? Before you condemn the fuel pump, the real culprit is often a faulty Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen this exact scenario countless times. The FSCM is the brain that commands the fuel pump, regulating fuel pressure and flow. When it fails, it starves your engine of the fuel it needs, leading to poor performance and leaving you stranded.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and high cost of dealership programming out of the equation. Simply provide us with your vehicle’s VIN after purchase, and we will flash this module with the latest, most stable software directly from GM. This ensures perfect communication with your vehicle’s computer systems and restores performance to factory specifications. This pre-programmed 2010-2012 Escalade ESV FSCM is the most efficient way to get your truck or SUV back on the road with confidence.
A Technician’s Notebook: The P069E Puzzle
A customer brought in his 2011 Sierra with a persistent Check Engine Light and intermittent stalling. The code was P069E – Fuel Pump Control Module Requested MIL Illumination. He had already spent a significant amount of money replacing the in-tank fuel pump, but the problem remained. After a quick diagnostic check, I confirmed the fuel pump was fine. The issue was the FSCM, which is mounted on the frame rail and exposed to years of road salt and moisture. The original module’s internal circuits had failed. We installed one of our VIN-programmed modules, cleared the codes, and the truck ran perfectly. It’s a classic case where diagnosing the ‘brain’ before the ‘muscle’ saves time and money.
Is Your Vehicle Showing These Symptoms?
- ✔ Engine cranks but will not start
- ✔ Vehicle stalls unexpectedly, especially under load
- ✔ Rough idling or hesitation during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light with codes like P069E, U0109, or P0230
- ✔ A “Service Fuel System” message on the driver information center
A Straightforward Guide to Installation
Replacing the 2010-2012 Escalade ESV FSCM is a job most DIYers can handle in their own driveway. On most GM trucks and SUVs like the Escalade, it’s located on the driver’s side frame rail, near the spare tire.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: Find the FSCM mounted to the frame rail. It’s a small, black plastic box with electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical harnesses. Then, remove the bolts or nuts (typically 10mm or 13mm) securing the module to its bracket.
- Install the New Module: Mount your new, pre-programmed FSCM onto the bracket and tighten the fasteners.
- Reconnect and Finalize: Plug the electrical connectors back in until they click securely. Reconnect the battery terminal. The vehicle is now ready to start with no further programming needed.

Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN (Vehicle Identification Number) allows us to program the module with the exact software calibration specified by GM for your vehicle’s specific configuration. This ensures seamless integration and optimal performance without a trip to the dealer.
Is this part difficult to install?
No, for most trucks and SUVs like the Escalade, this is a straightforward DIY repair. The module is typically mounted on the frame rail and is accessible with basic hand tools. Our pre-programming makes it a true plug-and-play solution.
Will this fix a P069E code?
Yes, a faulty FSCM is the most common cause of a P069E trouble code. While you should always perform a full diagnosis, replacing a failed module with this pre-programmed unit is the definitive repair for that code.
What is the difference between this and the fuel pump?
The fuel pump is the physical pump inside your gas tank that moves fuel. This FSCM is the electronic ‘brain’ that tells the fuel pump how fast to run and when. They work together, but a failure in this module can mimic a bad fuel pump.
Are other part numbers compatible?
Yes, this module is a direct, updated replacement for several older part numbers, including 20791901, 20827745, and 20850927. It will function identically to the original part.
