2011 Case Puma 155 multicontroller handle buttons stopped working

[Harro]

Any ideas? All of the buttons on the handle stopped working. The throttle works as normal. All the other controls work and the tractor can be driven in both auto-shift modes. No fault codes but the orange hitch led keeps flashing. Hitch works fine. Is this a common fault with the multicontroller handle? The original handle part number 84209526 has been replaced with 47844023. Could that point to a possible problem with the older version?

Broken wire in the handle where it constantly moves ?

That was what I was hoping to find but the wires were checked and are fine. 5V was measured at the handle circuit board with ignition on.

Check the earth .

Does the controller appear in the list of communicating modules? Could give you some direction

Not sure where the list can be found but there is a button test procedure explained in the workshop manual, which I followed with no luck. So I took the risk and bought a new handle. All buttons work fine now so definitely something wrong with the old handle.
