Guidiance please for PTCU errors
Hi Everyone,

Could you help me identify the faults and suggest where I should start looking? From my understanding, there seems to be an issue in Circuit 1, which involves Pump 1, the low-temperature pump, and the switchover valve, all connected to the same cam bus.

I’m not sure where to locate these components. I assume I can test for continuity to determine where the cam bus might be broken.

Could someone with experience please guide me through troubleshooting this issue?
