Is Your Escalade EXT Stalling or Losing Power? The FSCM is a Likely Culprit.
If your 2010-2012 Cadillac Escalade EXT is suddenly stalling, hesitating during acceleration, or displaying the dreaded ‘Engine Power is Reduced’ message, you’re not alone. As a mechanic with over two decades of experience, I’ve seen this exact scenario play out countless times. More often than not, the issue isn’t the fuel pump itself, but this small electronic brain: the Fuel System Control Module (FSCM). Located on the frame rail, it’s constantly exposed to the elements, leading to internal corrosion and failure.

Simply provide us with your vehicle’s VIN after purchase, and we will program this module with the latest GM software specifically for your Escalade EXT. It arrives at your door ready to be installed.

Expert Pro Tip from 20+ Years on the Floor: Before plugging in your new module, take a moment to inspect and clean the vehicle-side harness connectors. I use a small nylon brush and some electrical contact cleaner. These connectors, especially on frame-mounted modules like this one, are notorious for collecting dirt and moisture. A clean, solid connection is critical for the long-term health of your new FSCM.
