Referencing the service manual, I see there are a few Service Call codes, none of them end with 160 though. Could it be:
100000E0 CPU address error (load)
100000C0 (A/C Power shut Off)
10000180 CPU reserved command code exception error
It appears that all of the 10000___ codes are CPU related in one way or another, this code is indicating a problem with the CPU, you need to determine which code it is.
