FMS using can bus

[KSUMAAAA8]

I have to get details like Total Engine Hours, Total fuel consumed, PTO status, Engine RPM, Total Vehicle Distance, Vehicle speed from Volvo truck 440 and 460.
There are 2 Can Bus in that. One with 250kbps and other eith 500kbps. We are able to take engine rpm and accelerator pedal position perfectly.
We are able to find he message id and message of Total Engine Hours. But a proper fornula is not known.
Other items we are able to take.
I need to know the protocol for these items

Volvo truck 440 and 460.

These Volvo trucks were never sold in US market. This is a Volvo car forum, not Volvo trucks.
