New Code U062F - Unassigned

[Chrisw253]

Engine light came on... again... already had the ECM reprogrammed twice.  This time it brought up a code that comes up under the GM system as unassigned... my service writer didn't know what its was.  I am dropping off next Tuesday, just curious if anyone else has seen this code?

Anyone else getting this code?  Ive been to the shop 6 times already and under 4k mi.  Everytime I go in its not in failure so there isn't much they can do... plus they don't seem to know what that code is.  The above and these two are the last three codes pulled.

U062F means that ECM has lost communications with auxiliary coolant pump on LIN bus
