PCM is Power Train Control Module, and what stands out here is belt.

Does the alternator work? Is the battery charging? -- The ECU sends a 5 volt signal to the alternator to excite the alternator field. That's starts the power generation. -- The P0622 code means that there is a problem with that signal. The alternator may still work because nothing is perfect and the alternator might have some residual magnetism to get the power generation ball rolling.
