Adding these new parameters increases the value of the OBD2 software you have. All these parameters are available for our existing customers totally free. Just remember that in order for the software to be able to show the values, your car needs to support the sensors too. Typically, the newer the car the more values it supports.

If OBD II has detected a fault, you should find one or more “generic” codes (which start with the prefix “P0”), and maybe one or more “enhanced” codes (Caterpillar Diagnostic Tool specific codes that start with a “P1”). All OBD II compliant code readers and scan tools should be able to display generic codes, but some do not display all the OEM enhanced codes. As a result, you may not get the full picture of what’s going on if you’re using a tool with limited capabilities.
