Restore Power and Reliability to Your GM Vehicle
Is your 2010-2012 Cadillac Escalade or other GM truck/SUV experiencing frustrating issues like stalling, extended cranking times, or a sudden loss of power? Before you condemn the fuel pump, the real culprit is often a faulty Fuel System Control Module (FSCM). This critical component, also known as a fuel pump driver module, is responsible for precisely managing the voltage sent to your fuel pump. When it fails, it can leave you stranded. This isn’t just an inconvenience; it’s a reliability issue you can’t afford to ignore.
We offer a dependable and straightforward solution: a replacement FSCM, part number 20791901, that arrives at your door fully programmed with the latest GM software specific to your vehicle’s VIN. This eliminates the most significant hurdle of this repair—the expensive and time-consuming trip to the dealership for programming. Simply provide your VIN at checkout, and we handle the rest, ensuring a true plug-and-play installation.
A Technician’s Notebook: The Frame Rail Failure Point
In my 20+ years in the shop, I’ve seen hundreds of these GM trucks and SUVs come in with classic fuel delivery symptoms. The customer has often already replaced the fuel pump, only to have the problem persist. The first thing I check is the FSCM. On most of these trucks, GM mounted the module on the driver-side frame rail, just ahead of the rear axle. This spot exposes it to everything the road throws at it: water, salt, mud, and vibrations. Over time, moisture gets past the seals, corrodes the circuit board, and leads to intermittent or complete failure. A tell-tale sign is the P069E code stored in the ECM. This pre-programmed 2010-2012 Escalade FSCM is the direct fix for this common design flaw.
Is Your Vehicle Showing These Telltale Symptoms?
A failing FSCM can manifest in several ways. If you’re noticing any of the following, this module is the likely solution.
- ✔ Engine cranks but won’t start
- ✔ Stalling while driving, especially under load
- ✔ Hesitation or sputtering on acceleration
- ✔ “Reduced Engine Power” message on the dashboard
- ✔ Check Engine Light with specific trouble codes
- ✔ Common DTCs: P069E, P0230, P0606, or U0109 (Lost Communication With Fuel Pump Control Module)
A Straightforward Guide to Installation
One of the best parts about our VIN-programmed module is the simple installation process. You can do this in your own driveway with basic hand tools, saving you hundreds in labor costs.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs like the Escalade, Tahoe, and Silverado, the FSCM is mounted to the driver-side frame rail, near the spare tire. On some cars like the CTS or LaCrosse, it may be in the trunk or rear compartment.
- Disconnect and Remove: Unplug the electrical connectors. Be gentle with the locking tabs. Then, remove the bolts or nuts holding the module to its bracket or the frame.
- Install the New Module: Mount your new, pre-programmed FSCM in the same location and secure it with the original hardware.
- Reconnect and Finalize: Plug the electrical connectors back in until they click securely. Reconnect your battery terminal. The vehicle is now ready to start with no further programming required.
