Restore Your Cadillac’s Performance and Reliability
Is your 2010-2012 Cadillac CTS experiencing frustrating issues like intermittent stalling, hesitation during acceleration, or a complete no-start condition? Before you condemn the fuel pump, the culprit is often its electronic controller. This Fuel System Control Module (FSCM), also known as a fuel pump driver module, is the critical component that regulates voltage to the fuel pump, ensuring your engine gets the precise amount of fuel it needs. When it fails, it can leave you stranded and scratching your head.
A Technician’s Notebook: The Intermittent Stall Case
I remember a 2011 CTS that came into my bay with a ghost of a problem. The owner said it would die randomly at stoplights, but then start right back up. No consistent check engine light, but I managed to pull a history code—P069E (Fuel Pump Control Module Commanded OFF). Instead of just throwing a fuel pump at it, we checked the command signal to this exact module. We found the FSCM, located in the LH rear compartment on the CTS, was overheating and intermittently cutting power. We replaced it with a VIN-programmed module like this one, and the problem was solved for good. It’s a textbook failure I’ve seen dozens of times on these platforms.
Common Signs of a Failing FSCM
If your vehicle is exhibiting any of these symptoms, a faulty fuel module is a likely cause. Replacing your 2010-2012 CTS Fuel Module can be the definitive solution.
- ✔ Engine cranks but will not start.
- ✔ Vehicle stalls unexpectedly, especially when warm.
- ✔ Loss of power or hesitation under acceleration.
- ✔ A loud whining noise from the fuel pump as it runs at maximum duty cycle.
- ✔ Check Engine Light with codes such as P069E, P0230, or U0107 (Lost Communication With Fuel Pump Control Module).

A Straightforward Guide to Installation
Installing your new 2010-2012 CTS Fuel Module is a manageable job for a confident DIYer. On the CTS, it’s typically located in the trunk/rear compartment area.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On the 2010-2012 CTS, you’ll find the FSCM located in the left-hand (driver’s side) rear compartment, behind the trunk liner.
- Access the Module: Carefully remove any trunk trim panels or carpeting necessary to gain clear access to the old module.
- Disconnect and Remove: Unplug the electrical connectors from the old FSCM. Then, unbolt the module from its mounting bracket. Note the orientation of the connectors.
- Install the New Module: Mount your new, pre-programmed module in the same location and orientation. Reconnect the electrical connectors securely until they click.
- Reassemble and Test: Reinstall the trunk liners and panels. Reconnect the negative battery terminal. Turn the key to the ‘On’ position for a few seconds to allow the fuel system to prime before starting the engine.
