[Funny Farmer]

Out of the blue whilst sat idling our telehandler just stopped. It restarts but shuts down again immediately. Dash is showing a red star shaped thing with the code : U1501-88

I have wagons to load so its a real bad time, does anyone have any idea what it may be please?

Did you fix this problem?

Yes and no! I called out the dealer and they traced it to a canbus error caused by a relay failure, the relay is the once that powers up the engine ECU. The relay was replaced and the machine ran fine for a while then it's started again with the same fault, I can get the fault to go away by banging the relay box so I think it might be a dry joint on the PCB in there, I can do this and it will run for a bit but it's not got much to do this time of year so I've been managing. I am going to have to get them out again soon so we'll see.
