Without serial its hard to say but try going into dash if newer until you get to throttle or accelerator and follow instructions the newer ones you can set that way you also set inching that way if newer than 2017

I assume you mean pedal ? Depending on the serial number and engine this part is generally not calibrated. If it says comsys on the side it is plug and play. If you are getting accelerator pedal faults you either have bad wiring or a bad accelerator pedal assembly. You didn't provide any info on the failure so I can't give you any more info than that.
