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 (FICM)
The FICM receives input from the PCM. Based on the information received and programmed into its memory, the FICM generates output signals to control the injector solenoids. The FICM contains a set of drivers for both the primary (forward) and secondary (rearward) fuel injectors. Fuel injector driver signals from the powertrain control module (PCM) are used to control both sets of output drivers in the FICM. Based on the fuel selector switch input, the FICM controls either the primary or both the primary and secondary fuel injectors.
