EDC Iveco Eurotrakker Cursor

I need to know what element is the one within EDC MS6.2 of the 4 -axis truck Iveco Eurotrakker cursor. It is an element that is within the switchboard in a section of pin B3 in which the cable is not armored and the aforementioned element causes me current problems (I did not miss the current).
I will need to know if it is a potentiometer, a capacitor, a diode ... to be able to replace it.

Thanks in advance and greeting to all

P. I do not be of importance that the frame and other elements of the vehicle are Astra and other Iveco
