Here's what my tech form stated (verbatim) for those having similar problems:
"10220 Power supply relay faulty interrogate fault memory found faults 2EFE 2F17 oil temp. Perform test plan for 2EFE and fan tested Ok as per relay not supplying power to fan. Remove rt ft inner fender to gain access to relay and replace power supply relay. Work time for performing test moduals for fan and DME. Check for power at fan pin 2 of X1797 found none. Check for pwoer at x17278 found ok check for power at x 17279 found none. Check for power at x17282 pin 1 and 2 found ok found no power going thru relay and dme ok."
Seems to me the fault is 2EFE that we have in common.
