Hello all,

1.Go into the console and change the parameter 150 from 00 to 01.
2. Restart the truck and you will see the errors if exist.

Normaly the truck is driving slow under 5 km/h when are problems with the speed sensors or temperature sensors from the traction motors, or the sensor from steering (it is inside the console) on the steering colum is a dent wheel and that should be set up wright, in the diagnostic software for this exist a setting ( there are 3 type of dent wheel one with 14 one with 15 and one with 45 teeth) normally shold be ok if nobody changed it, or the switch from hand brake or the potentiometer from break pedal is out of range. The sensors for speed reduction can also be the problem, to exclude them suspend the truck (the front wheels must not tuch the ground) and drive the truck in straight line, if only one wheel is moving then you found the problem (or you can just disconect them). From the console reset the truck.

If you need more help just post here the message.
