on 2016 and newer ere machines there is a factory fault with brake and motor temp sensor electrical instalation, wires brakes inside connectors due to poor strain relife.
solution is to cut the connector, replace it with new one and leave it without zip ties just floating in free air.

I have same error on Ere 225 , when i tried to diagnose with UMS 100 for jungheinrich it said to check three key switch inputs and wires and if ok ,then replace controller.
same code i had trouble is was giving the control unit , contactors and breake pad was almost gone, it didtn have break.

Most controllers switch using a basic open collector circuit. An internal transistor is switched on by applying a forward biasing signal to the base emitter circuit. When the transistor base is forward biased the transistor is switched on allowing current to flow from the collector across the junction to the emitter and to ground or battery negative, usually through a current limiting resistor.
Now as the transistor is switching an inductive load it will experience high back emf which depending on the loads inductance and speed of switching can destroy the transistor (e=-Ldi/dt) hence a freewheel diode is placed in parallel to the inductive load to prevent the transistor seeing this high voltage. The most common failure mode is for the diode to fail which in turn causes the transistor to fail.
So identify the switching transistor on the board, test and if faulty replace it AND the freewheel diode, otherwise it WILL fail again

well you can always try what is suggested by little forker and put the brake unit on another machine and see if it works.
Or you can apply signal voltage to it and usually you can hear it clicking in (actuating) for releasing.

when you removed the cover did you notice anything about the standoff's where the power cables hook to it? they should be fixed in a solid position, not loose. If any of them are loose then the controller will have to he replaced.

Do you have another truck that you could try the brake unit on?

I have never had a faulty controller give out this fault code before

I removed the cover off the controler.
all the connectors inside the controler are ok.
There's nothing inside what looks bad.

i think the best option is replace the controler but thats verry expensive.......

thanks for the support sofar

yes
no load you will have a + volt signal
when load you will see 0v

pretty much any control these days uses negative switching so generally you will see a + voltage when no load.

reading these codes are not like most codes
they are broken down into segments
E designates it as an event code
1 designates the function group which is 'travel'
5 designates the event group which is 'hardware'
04 designates the event number which is an output error in phase of V and W phase of transformer.

manual recommends replacement of controller.

now in some cases you can remove the cover of the controller and access the internal circuit boards and there should be ribbon cables connecting them together, i have seen these vibrate loose and cause errors such as this. Caterpillars fix was to clean, reinsert the connectors and apply silicone sealer to hold them in place.

Also i have seen tech's overtorque the cables and actually break the standoff loose from the heatsink inside the controller, if this is the case there is no fix for this and the controller has to be replaced.

good luck, hope this helps

When i measure the ouput without the brake it gaves 13,5 volt

when i connect the brake i measure 0,2 volt

is that right?

Check the brake connection under load. connection may seem okay but fails on start up. The brake is controlled from the micropulse but unlikely for it to be throwing up this code

i checked the brake and it works ok
also the wires to the brakes are good

do you have other sugestions?

Check the connection to the magnetic brake on the drive motor, if that is okay them check the brake itself
