I would like to know how does apps like Torque calculate if my car (Hyundai i10 Era) is 'Not ready' yet? What are the factors (complete list) do one checks to decide? Is there any formula to calculate readiness (which I guess, there is none)


There are not calculations. The car has a list of PIDs that the tool checks.

The readiness monitors are a set of tests that the car runs including but not limited to EVAP, EGR, CATALIST, O2, FUEL, COMPREHENSIVE. When the codes in a car are cleared all the PID values for the monitors are cleared. As the car completes and passes the necessary tests it will set the PID values to pass.

The scan tool or App does nothing other than just reads the values.

  • Can you please tell me which PIDs to hit for this – Soumya Sen Jan 6 '16 at 19:59

    @SoumyaSen I use a scan tool that sorts and displays the data for me. I never manually pull the data manually. – vini_i Jan 6 '16 at 20:13
  • Can you please give me any reference where I can find the list of tests to perform to check whether my car is ready.... An exhaustive list – Soumya Sen Jan 9 '16 at 15:23
