Function Inspection
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine off).
- Display the PCM PIDs EVAP_PRES and FTP. (See PID/DATA MONITOR INSPECTION .) (See PID/DATA MONITOR TABLE [PCM (SKYACTIV-G VIN M)] .)
- Disconnect the quick release connector (Fuel tank side) connected to the charcoal canister.
- Verify the PIDs EVAP_PRES and FTP value are as specified.STANDARD SPECIFICATION
EVAP_PRES FTP V kPa {kgf/cm2 , psi}(1) Approx. 2.5 Approx. 0 {0, 0} (1) The fuel tank pressure displayed on the M-MDS indicates the difference between the pressure and the barometric pressure. - If the specified value can be verified, go to the next step.
- If the specified value cannot be verified, replace the PCM. (See PCM REMOVAL/INSTALLATION .)
- Verify that the voltage output from the fuel tank pressure sensor (PID: EVAP_PRES) changes when pressure is applied to the port on the fuel tank side of the charcoal canister.
