Hi all - I have a Electric 7BRE16-1 Three wheel electric reach forklift for my workshop and it has a number of error codes. I am an Ag engineer and capable of diagnosis but could do with knowing how to scroll through menus and see if calibrations can be done. I have a 125 code which I think is associated to the steer wheel potentiometer. I have a new one but before I fit it I want to know if I can calibrate this by myself. Do I need a CAN reader of somekind? Cheers
