Thanks Nemanja, I have checked the speed sensor - canbus and cleaned all the connection of the inverter. Now the truck can run without error code but only on creep speed.
I have used the Steds diagnostic to check the acc potentiometer voltage, i saw that when the drive inscrease the speed from 0-50% max speed the truck speed will follow - on the other hand if the driver increase more than 50% the speed will be dropped down to Zero again. I have done calibration the Acc. potentiomtera again but the problem is not solved yet.
Do you have any more experiences on this matter ?
Regards
Nuna
