Have a intermittent fault on my hitachi which is getting more frequent,the fault I have is the machine loses its revs and goes to idle, fault on dash is work mode alarm . I have plugged in my dr zx and I’m getting no reply to main e/u and no detect on engine c/u . Anyone came across this or had same problem
Found problem with machine. Main controller on back of cab, plug had 2x blue wires corroded. Repaired and machine is better than ever, like a new machine
