Generic Function Module 2 (GFM2)

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

The GFM2 is the ECU for the vehicle dynamic suspension system and the vehicle fuel level. The GFM2 monitors all sensor inputs and all HS-CAN messages relating to the vehicle dynamic suspension and then directly controls the valve solenoids in the shocks and struts. The GFM2 sends a PWM signal to each valve solenoid to control the amount of damping required.

When the front strut assembly or rear shock is disassembled, disconnected or removed, the GFM2 sends out a "signal faulty" message and sets the appropriate DTC.
