I had my 2015 GC in for warranty work (door hinge) and they also did:
Software Flash for TCM (Flash Software 1)
Software Flash for PCM (Flash Software 2)
Software Flash for TPM (Flash Software 3)
What are these software flashes for?
2015 Grand Cherokee Limited 4X4
Max Steel Metallic; Black/Light Frost
3.6 V6; Advanced Tech Group; Lux Group II; ORA II and Uconnect 8.4AN
