How is fault code P0611 fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Read all stored codes and the freeze-frame data, then check the basics before anything else. A dying battery or a poor earth will throw a module performance code while the module is perfectly healthy. Confirm supply voltage at the FICM holds steady, roughly 11.8V to 13.2V under load 2. Inspect the FICM connector and harness properly. Unplug it, look for green crust on the pins, spread or pushed-back terminals, and check the loom for chafing or heat damage near the engine 3. Wiggle-test the connectors and wiring with live data running. If the fault flickers in and out as you move the loom, you've found a connection problem rather than a dead module 4. Look at live injector pulse-width and timing on the scanner. Zero or wildly erratic values point firmly at the module losing the plot 5. Run a CAN-bus check. If the FICM won't answer the scan tool at all, you're dealing with a communication or power fault to the module, not a fuelling issue 6. Once wiring, earths and supply are confirmed go
