Source and target (PID) addresses

[WizKid22]

I captured a slew of messages and I'm trying to decode them. All values in hex

Source address, Target address
10, 53 I think 10=PCM or ECM, and 53= engine systems, is this correct? Can anyone give an example of an engine system? actual message: 88 53 10 4 C4 not sure what this message does?
40, FF No idea what 40 is, I think FF is Network control, not sure what that means? Actual message: 28 FF 40 06 07 02 0A 88 not sure what this message does?
60, EB 60 might be related to displays (I think that means instruments) again not sure what this message is about? actual message: AA EB 60 20 C9 00 97

Can anyone provide any insight?

Thank you for your help
