Restore Your Escalade’s Performance and Reliability
Is your 2010-2012 Cadillac Escalade EXT experiencing frustrating issues like stalling, hesitation on acceleration, or a no-start condition? A failing Fuel System Control Module (FSCM) is often the culprit. 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. In my 20+ years as a technician, I’ve seen countless GM trucks and SUVs with these exact symptoms, and a faulty FSCM is one of the first things I check.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and high cost of dealer service out of the equation. Each 2010-2012 Escalade EXT 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, no special tools required—just a straightforward installation to get you back on the road with confidence.
From the Diagnostic Bay: The Intermittent Stall Case
A customer brought in his 2011 Escalade with a problem that was driving him crazy: it would randomly stall at low speeds and sometimes refuse to restart for 10-15 minutes. There were no consistent check engine lights, but a deep scan pulled a history code, U0109 – Lost Communication With Fuel Pump Control Module. These modules are mounted on the frame rail, exposed to water, salt, and road vibration, leading to internal corrosion and intermittent failures. He had already replaced the fuel pump, with no success. We installed one of our VIN-programmed FSCMs, and the problem was solved instantly. The pre-programming ensured it communicated perfectly with the ECM right out of the box, saving hours of diagnostic guesswork.
Is Your Escalade Showing These Symptoms?
A failing FSCM can manifest in several ways. If you’re noticing any of the following, this module is the likely solution:
- ✔ Engine stalling, especially at idle or low speeds
- ✔ Vehicle cranks but will not start
- ✔ Hesitation or stumbling during acceleration
- ✔ Reduced engine power and performance
- ✔ An active Check Engine Light with codes such as P069E, P0230, P2635, or U0109
A Straightforward Guide to Installation
Replacing the FSCM on your GM truck or SUV is a job most DIYers can handle in their own driveway. Our pre-programmed module makes it even simpler.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On most trucks and SUVs like the Escalade, the FSCM is mounted to the driver’s side frame rail, typically near the spare tire.
- Disconnect and Remove: Carefully unplug the electrical connectors. Then, remove the bolts or nuts holding the old module to 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 Test: Plug the electrical connectors firmly into the new module. Reconnect the battery terminal, cycle the key a few times to prime the fuel system, and start the engine.

Frequently Asked Questions
What exactly does a Fuel System Control Module do?
The FSCM acts as a smart controller for your fuel pump. Instead of the pump running at full speed all the time, the FSCM receives commands from the Engine Control Module (ECM) and adjusts the voltage to the pump. This provides precise fuel pressure and volume based on engine demand, improving efficiency and performance.
Why do I need to provide my VIN?
Your vehicle’s VIN is essential for us to program the module correctly. This programming ensures the FSCM has the right software and calibrations to communicate seamlessly with your vehicle’s other computers, like the ECM and BCM. This step eliminates the need for a dealer visit and ensures a true plug-and-play installation.
Is this a difficult part to install myself?
For most individuals with basic hand tools, this is a very manageable repair. The module is typically located on the vehicle’s frame rail and is accessible without major disassembly. Since our module comes pre-programmed, the most complex part of the job is already done for you.
Will this fix a P069E check engine light code?
Yes, in the vast majority of cases. DTC P069E (Fuel Pump Control Module Commanded OFF) is one of the most common codes indicating a failed FSCM. Replacing the faulty module with this pre-programmed unit is the correct fix for this code.
What happens after I place my order?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message. Once we receive your VIN, our technicians will program the module and ship it out to you, ready for installation.
