Orange means a sticky fault is set. I'm guessing StickyFaultVbus is '1'. It might be easier to just post the screenshot of the self-test.
Assuming it's the vbus fault, this means that the PDP saw battery voltage below 6.5V once. Anytime it sees a low vbus, the sticky fault is set and can be cleared through web interface. Be sure to check battery voltage reported in the PDP before clearing the fault to ensure it the problem is resolved.
Check out section 5.1 in PDP's User Manual.
