As of z/OS 1.12, when there is more than one CPU, the LCCA and PCCA are above 16M by default. You can force them below 16M by specifying CBLOC VIRTUAL24(IHALCCA,IHAPCCA) in the DIAGxx specified pointed to by IEASYSxx. Of course, your program does not have serialization to the PCCA it is accessing, so it has always been subject to possible random 0C4 abends if a CPU gets CONFIGed OFFLINE while your program is accessing its PCCA.
