blocking fault
For each failure, check the internal code. For failures about digital electro valves controlled by the U104 ECU (platform slave ECU) : The detected failures are "open circuit" or "short circuit", check the harness between the ECU and the hydraulic block controlling the movement, check the valves. For failures about proportional or digital electro valves controlled by U106 ECU (turret master ECU) : The detected failures are open circuit ( OC), short-circuit to VBAT (SC+) , short-circuit to GROUND ( SC-), low current ( LC) and power supply error ( PSE).First check the type of failure by reading the status of the output in the menu INPUTS-OUTPUTS => DIGITAL OUTPUTS / ANALOGUE OUTPUTS. If OC/SC+/SC-/LC : check harness, check there is no misconnection between signal and ground supply or power supply. If PSE : Check the supplies are well connected : 12VD1 (1B.18) 12VD2 (2A.08) 12VD3 (2B.02) 12VD4 (3A.01) 12VF1 (1B.32) 12VF2 (2A.07) 12VF4 (3A.07) For the steering solenoid valves (movement and mode), movement (speed), brake release and oscillating axle : check connection to electrical collector. [case 1] b0 Proportional output's failure : with or without movement --> YV900 [case 2] b1 Digital output's failure : Left steering movement (with or without movement) --> YV150L [case 4] b2 Digital output's failure : Right steering movement (with or without movement) --> YV150R

A machine with an active blocking code must not be used until the cause has been removed.
Does code F04.01 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.
