I succesfully decoded can-bus data from a VW Caddy, but know nothing about OBD and trucks.
For a research I need now to read a truck's exhaust temperature (EGT sensor), possibly by OBD. I would prefer this method instead of going through FMS (that is normally hidden into the dashboard) or pure can-bus (a little nightmare on its own, both because of finding the access points and the incompatibility among producers).
Is this parameter normally accessible (i.e. in Volvo trucks)? Is there any info available on the Net about reading parameters from trucks?
Or could you suggest other ways to read this parameter?
I am going through California's ODB regulations at https://www.arb.ca.gov/msprog/obdprog/hdobdreg.htm at the moment.
Thank you in advance
