That fault (118) refers to the Nav losing communication with the PVED valve. When the fault occurs does the Tractor Icon on the Agco command center disappear? If so then it's related to a bad CAN wire on the Agco side. (Possibly the wiring harness that connects to the command armwrest or bad PVED valve). What model is the tractor?
