Hi ,
That´s the only code , has a fingertip control , i guess it´s a multi pilot control , the truck is from 2014 or 2015.
Hope to ear from you soon.
Thanks.

are there any other codes besides the 4311? Also, does this truck have a solo pilot, or multi pilot controls? Year of truck?

Hi ,
First of all , thanks for the hints , I´ll check all.
Answers :
- Key on and code out ,yes
- Still have drive function , yes
- Code out before touching hidraulical controls , yes
If , there is anything more , that we con test , please , avise.
Hope to ear from you soon.
Thanks.

"Hydraulic function 1 input" setpoint implausible - Check wire connection, hydraulic set point device power supply, replace hydraulic set point device, replace control.

What are the symptoms of the truck? Key on and code out? Do you still have drive function? Does it code out before touching hydraulic controls or do you have to command hydraulic function before it codes out?
