Restore Your Escalade’s Performance with a Plug-and-Play Solution
Is your 2010-2012 Cadillac Escalade EXT experiencing frustrating issues like stalling, rough idling, or a complete no-start condition? Before you blame the fuel pump, the real culprit is often a failed Fuel System Control Module (FSCM). This critical component, also known as the fuel pump driver module, regulates the voltage sent to the fuel pump, ensuring your engine gets the precise amount of fuel it needs. When it fails, it can leave you stranded and facing a costly repair bill from the dealership.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the equation by pre-programming this module to your vehicle’s specific VIN. By providing us with your VIN at checkout, we load the latest GM-certified software onto the module before it even leaves our facility. This means no extra trips to the dealer, no expensive programming fees, and no special scan tools required for installation. You get a reliable fix that restores factory performance and fuel efficiency, right out of the box.
Case Study: A Tricky Diagnosis
A customer brought in an ’11 Sierra with classic fuel-starvation symptoms: it would crank but not start, and when it did, it would sputter and die. The local shop had already replaced the fuel pump, but the problem persisted. They were stumped. I hooked up my scanner and saw DTC U0109 (Lost Communication With Fuel Pump Control Module). Instead of just throwing parts at it, I went straight to the FSCM, located on the frame rail. It was covered in road grime and corrosion—a common failure point. After swapping in a pre-programmed module like this one, the truck fired up instantly and ran perfectly. It saved the customer hundreds by correctly identifying the FSCM as the root cause, not the pump.
Is Your Truck Showing These Symptoms?
A failing FSCM can mimic other fuel system problems. Here are the most common indicators that point directly to this module. If you’re seeing these signs, our pre-programmed 2010-2012 Escalade EXT FSCM is the definitive fix.
- âś” Engine cranks but refuses to start
- âś” Vehicle starts, then immediately stalls
- âś” Severe hesitation or stumbling under acceleration
- âś” Reduced engine power and poor fuel economy
- âś” Check Engine Light with codes like P069E, P0230, or U0109
- âś” A buzzing or whining noise from the fuel pump area that is inconsistent
A Straightforward Guide to Installation
Installing your new fuel system control module is a job most DIYers can handle with basic hand tools. Since we’ve done the programming, it’s a true plug-and-play process.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most GM trucks and SUVs like the Escalade EXT, the FSCM is mounted to the driver’s side frame rail, typically above the spare tire. You may need to lower the spare tire for easier access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, remove the bolts or nuts holding the module to the frame. These can sometimes be corroded, so a little penetrating oil might help.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location, securing it with the original hardware. Ensure it is mounted securely.
- Reconnect and Finalize: Plug the electrical connectors firmly into the new module. You’ll hear a click when they are seated properly. Reconnect the negative battery terminal.
- Prime the System: Turn the key to the ‘On’ position (without starting the engine) for a few seconds to allow the fuel pump to prime the system. Start the vehicle and check for proper operation.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN is required so we can program the module with the exact software and calibrations for your specific Escalade EXT. This ensures perfect compatibility and function without needing a trip to the dealer.
Is this part difficult to install?
No, this is a very DIY-friendly repair. Since the programming is done beforehand, it’s a simple unbolt-and-unplug process. Basic hand tools are all that’s needed. See our installation guide above for the steps.
Will this fix a P069E check engine code?
Yes, the Diagnostic Trouble Code P069E (Fuel Pump Control Module Commanded Performance) is one of the most common codes indicating a failed FSCM. Replacing it with our pre-programmed module is the correct fix for this issue.
What is the difference between this and the module at the auto parts store?
A module from a local parts store comes blank. You would still need to take your vehicle to a dealership or a properly equipped shop to have it programmed, adding significant cost and downtime. Ours arrives ready to install.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for several part numbers, including 20791901, 20827745, 20877116, and 20850927. If your old module has any of these numbers, this part will work perfectly.
