Cat TH360 B ECM Fault

Hi,

Cat TH360B 2003

Serial CSLE00405

Today when starting it the red exclamation mark warning started to flash. When i checked the codes I got 039 and A039 ECM. It goes forward and backwards fine and the tilt control works for the body but all other hydraulics dont work.

Left it for a couple of hours and it works with the exclamation mark gone. Then after 5 minutes of using it pops up again and shuts down the hydraulics to the boom etc.

Any ideas where to start.
