STEP 1. Using scan tool (M.U.T.-IIISE), read the diagnostic trouble code (DTC).
STEP 2. Check of harness damage in ECOV line between evaporative leak check module connector and ECM connector.
STEP 3. Check of harness damage in EVSS line between evaporative leak check module connector and ECM connector.
STEP 4. Check of harness damage in EVS line between evaporative leak check module connector and ECM connector.
STEP 5. Check of harness damage in EVSE line between evaporative leak check module connector and ECM connector.
STEP 6. Check of harness damage in COVB line between MFI relay connector and evaporative leak check module connector.
STEP 7. Check of short circuit, open circuit and harness damage in EVB line between evaporative leak check module connector and ECM connector.
STEP 8. Check of open circuit and harness damage in E line between evaporative leak check module connector and ground.
STEP 9. Replace the evaporative leak check module (integrated in evaporative emission canister).
(1) Replace the evaporative leak check module (integrated in evaporative emission canister).
(2) Carry out an evaporative emission system monitor. Refer to Evaporative Emission System Monitor Test . (3) Check the item 189, Vent Valve Stuck Closed or Pump in the data list.
(4) Turn off the power supply mode of the electric motor switch.
Is the data list "Normal"?
The inspection is complete. Replace the ECM (Refer to Removal and Installation ). Then go to Step 10.
STEP 10. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 3 . (2) Check the diagnostic trouble code (DTC).
Is DTC P24C0 set?
Retry the troubleshooting. The inspection is complete.
