Code 22 is the ignition circuit = PTU. Check the connections at both ends of the PTU as well at the COP's might just be a loose, dirty or damp connection.

+1 for the two PTU connectors in that ridiculous harness, they will be corroded with the green gunk most likely and will work for long periods, but then one day...and usually like yours, after repairs.
