Restore Peak Performance to Your Cadillac
Is your 2010-2012 Cadillac CTS experiencing frustrating issues like stalling, hesitation on acceleration, or a dreaded crank-no-start condition? Before you suspect the fuel pump, the real culprit is often a failing Fuel System Control Module (FSCM). As an experienced technician, I’ve seen countless hours and dollars wasted on replacing perfectly good fuel pumps when this module was the root cause. The FSCM is the brain of your fuel delivery system, and when it falters, it starves your engine of the fuel it needs to run smoothly and reliably.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair by pre-programming this 2010-2012 CTS Fuel Module to your vehicle’s specific VIN with the latest GM-approved software. This means you can skip the dealership appointment and the programming fees. It arrives at your door ready for a straightforward, plug-and-play installation, getting you back on the road with confidence.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 CTS that would intermittently stall at red lights and hesitate when merging onto the highway. They had already replaced the in-tank fuel pump, but the problem persisted. A quick scan showed a P069E code (Fuel Pump Control Module Requested MIL Illumination). Instead of just throwing more parts at it, we checked the command signal to the FSCM. The signal was good, but the output voltage to the pump was erratic. This confirmed the FSCM was failing internally. By installing a VIN-programmed module like this one, we provided a permanent fix in under an hour, saving the customer from further misdiagnosis and expense.
Is Your CTS Showing These Telltale Signs?
- ✔ Engine cranks but refuses to start
- ✔ Intermittent stalling, especially when warm or under load
- ✔ Sputtering or hesitation during acceleration
- ✔ Noticeable loss of engine power
- ✔ Check Engine Light on with diagnostic trouble codes (DTCs) such as P069E, P0230, P0606, or U0100
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Access the Module: On the 2010-2012 Cadillac CTS, the FSCM is located in the trunk. You will need to remove the left-hand (driver’s side) trim panel or liner to expose it.
- ✔ Disconnect the Old Module: Carefully unplug the electrical connectors. Press the release tabs firmly to avoid damaging the clips. Then, unbolt the old module from its mounting point.
- ✔ Mount the New Module: Secure your new, pre-programmed 2010-2012 CTS Fuel Module onto the mounting bracket.
- ✔ Reconnect and Secure: Plug the electrical connectors into the new FSCM. You should hear and feel a distinct click, ensuring a solid connection.
- ✔ Final Assembly: Reinstall the trunk trim panel, reconnect the negative battery terminal, and start the engine to confirm the repair is successful.
