This can happen if the pedals are not connected properly. The cable arrangement is different if you are using the CSL Pedals Load Cell Kit. We have described the cable connections with and without Load Cell Kit below, please follow them carefully: 

Without Load Cell Kit: 

Gas pedal to wheel base (Gas 'Wheel Base/Load Cell' port TO 'Pedals' port in the wheel base) 

Brake pedal to Gas pedal (Brake RJ12 connector TO 'Brake' port in Gas pedal) 

With Load Cell Kit: 

Load Cell pedal to wheel base (Load Cell 'Wheel Base' port TO 'Pedals' port in the wheel base) 

Gas pedal to Load Cell pedal (Gas 'Wheel Base/Load Cell' port TO 'Load Cell' port in the Load Cell pedal) 

Clutch to Gas pedal (Clutch RJ12 Connector TO 'Clutch' port in the Gas pedal)

Warning! Connecting the cables to the wrong ports can damage the electronics and prevent the pedals from functioning. 

In case the pedal is still not recognised, please reach out to our Technical Support by opening a support ticket via the My Products section of your Fanatec account.
