Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Injector Control Module
The Fuel Injection Control Module (FICM) self monitors injector driver performance and sends this information to the Engine Control Module (ECM) through the CAN system. FICM is located on top front of right valve cover. See Fig 1 . If a fault is detected in the injector driver circuits, the FICM will signal the ECM and a DTC will set. This is an internal circuit fault and cannot be caused by external failures.
