Inspection Procedure

NOTE: An intelligent tester is required to conduct the following diagnostic troubleshooting procedure.

HINT:

Using intelligent tester monitor results enables the EVAP (Evaporative Emission) system to be confirmed.
Read freeze frame data using an intelligent tester or OBD II scan tool. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air / fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

CONFIRM DTC
1. Turn the ignition switch OFF and wait for 10 seconds.
2. Turn the ignition switch ON.
3. Turn the ignition switch OFF and wait for 10 seconds.
4. Connect the intelligent tester to the DLC3.
5. Turn the ignition switch ON and press the intelligent tester switch ON.
6. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
7. Confirm DTCs and freeze frame data.
  If any EVAP system DTCs are set, the malfunctioning area can be determined using the table below.

  NOTE: If the 0.02 inch reference pressure difference between the first and second checks is greater than the specification, the DTCs corresponding to the reference pressure (P043E, P043F, P0441, P0455, P0456, P2401 and P2420) will all be all stored.
NEXT
PERFORM EVAP SYSTEM CHECK (AUTO OPERATION)
NOTE:
- In the EVAP SYSTEM CHECK (AUTO OPERATION), the series of 5 EVAP SYSTEM CHECK steps are performed automatically. It takes a maximum of approximately 18 minutes.
- Do not perform the EVAP SYSTEM CHECK when the fuel tank is more than 90% full because the cut-off valve may be closed and making the leak check of the fuel tank unavailable.
- Do not run the engine in this step.
- When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the EVAP SYSTEM CHECK, keep the temperature below 35°C (95°F).
1. Clear DTCs (See DTC CHECK / CLEAR ).
2. On the intelligent tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / SYSTEM CHECK / EVAP SYS CHECK / AUTO OPERATION.
3. After the EVAP SYSTEM CHECK is completed, check for pending DTCs by selecting the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / PENDING CODES.
  HINT:
  
  If no pending DTC is displayed, perform the Monitor Confirmation after this repair is completed. After this confirmation, check for pending DTCs. If no DTC is displayed, the EVAP system is normal.
NEXT
PERFORM EVAP SYSTEM CHECK (MANUAL OPERATION)

NOTE:
- In the EVAP SYSTEM CHECK (MANUAL OPERATION), the series of 5 EVAP SYSTEM CHECK steps is performed manually.
- Do not perform the EVAP SYSTEM CHECK when the fuel tank is more than 90% full because the cut-off valve may be closed, making the leak check of the fuel tank unavailable.
- Do not run the engine in this step.
- When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the EVAP SYSTEM CHECK, keep the temperature below 35°C (95°F).
1. Clear DTCs (See DTC CHECK / CLEAR ).
