Description from the Haulotte service manual, in the original wording.
Effect on the machine: --> YV112=FAIL --> YV113=FAIL --> YV114=FAIL --> YV115=FAIL --> YV110=FAIL --> YV111=FAIL
Possible causes
- Check YV112/YV114 : Check valves, check connection between the two U106 ECU outputs ( 690 wire), check connection to electrical collector, check connection between electrical collector and electro valves, check connections to ground.
- Check YV113/YV115 : Check valves, check connection between the two U106 ECU outputs ( 687 wire), check connection to electrical collector, check connection between electrical collector and electro valves, check connections to ground.
- Check YV112/YV114 : Check valves, check connection between the four U106 ECU outputs ( 690 wire), check connection to electrical collector, check connection between electrical collector and electro valves, check connections to ground.
- Check YV113/YV115 : Check valves, check connection between the four U106 ECU outputs ( 687 wire), check connection to electrical collector, check connection between electrical collector and electro valves, check connections to ground.
- Check YV110/YV111 : Check valves, check connection between the four U106 ECU outputs ( 686 wire), check connection to electrical collector, check connection between electrical collector and electro valves, check connections to ground.
What you can do
Switch the machine off with the emergency stop and switch it on again. If the code comes back, do not use the machine and call service.

The descriptions are quoted from the manufacturer's service documentation and are for guidance only. Clearing codes, calibrations and repairs are carried out by a qualified service technician according to the manual for the specific serial number. A machine with an active blocking code must not be used until the cause has been removed.
Does code F04.20 not go away?
RK Rental services Haulotte lifts at our workshop or on site at the customer's premises (construction site, factory, warehouse). We read the code, remove the cause and select the parts by serial number.
