Agree with Nunanemo, and will add to check the wires to the chassis valve block and not the reach carriage valve block. The chassis valve block is located inside the rear door panel cover by the foot step. The reach carriage valve block is obviously located on the reach carriage (under the removable plate) next to the reach cylinder.

FE60, Wire breakage/short-circuit at the valve outputs for lifting/lowering.
When a lift main lift command is given, a short-circuit or wire breakage is detected at output X10.4 (switching valve for lifting). The output is switched off.
When a lower main lift command is given, a short-circuit or wire breakage is detected at output X10.5 (proportional valve for lowering). The output is switched off.
Check the wiring and the valve (see "LAS module, Safety monitoring, Block diagram").

FE61, Wire breakage/short-circuit at the valve outputs for reaching
When the LS/DS reach command is given, a short-circuit or wire breakage is detected at outputs X10.6/X10.7 (proportional valves). The affected output is switched off.
Check the wiring and valve (see "LAS module, Safety monitoring, Block diagram").

Hope you get it sorted, shout if you need further assistance.

Hi,
1) Error FE60 => Broken wire at the hydraulic output for lifting/lowering
=> Check the wiring & the solenoid coil of the lifting /lowering valve to if one of them is broken.
2) Error FE 61 => Broken wire at the hydraulic output for reach
=> Check the wiring & the solenoid coil of the reach valve to if one of them is broken.
