I have a 330lc that is throwing a Z030 fault code and then reduces hydraulic power. I've searched the internet without finding much info on test procedures for this fault code. Has anyone had experience with this? Any help is appreciated.
Is there a troubleshooting procedure for the controller?
What year is the machine, what model is it - 8 etc. Have you tried carrying out an a+b adjustment, most of the time the ajustment will get rid of that fault
I found the turbo was bad. The VNT was operational but the nozzle was bad and sticking, not allowing it to get full boost.
