I see that in various nissan models, Fuel level is not supported in OBD. However the dashboard does show fuel level. How are they showing it? Is it some manufacture specific PID that is used? If i need to show fuel level to my customer, what are my options?

  • I’m voting to close this question because there is no programming problem to be solved. How/where to find OBD documentation isn't an on-topic question here. – Lundin Jul 01 '21 at 06:38

It is not necessary that the fuel level information goes to the dashboard only through OBD. Mostly this information will be going via some CAN frames. If you have the network description file of the CAN Bus, then you can identify which CAN ID carries this information and how to decode this.

  • Yes, No PID with respect to fuel level. Checked this using external can logistics tool as well – 230490 Jul 01 '21 at 13:57
