Inspection Procedure

NOTE: The Techstream is required to conduct the following diagnostic troubleshooting procedure.

HINT:

Using the Techstream monitor results enables the EVAP (Evaporative Emission) system to be confirmed.

Read freeze frame data using the Techstream. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

CONFIRM DTC
1. Turn the engine switch off and wait for 10 seconds.
2. Turn the engine switch on (IG).
3. Turn the engine switch off and wait for 10 seconds.
4. Connect the Techstream to the DLC3.
5. Turn the engine switch on (IG) and turn the Techstream ON.
6. Enter the following menus: Powertrain/Engine/Trouble 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 reference pressure difference between the first and second checks is greater than the specification, all the DTCs relating to the reference pressure (P043E, P043F, P2401, P2402 and P2419) are stored.
PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE)
NOTE:
- The Evaporative System Check (Automatic Mode) consists of five steps performed automatically by the Techstream. It takes a maximum of approximately 18 minutes.
- Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.
- Do not run the engine during this operation.
- 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 Evaporative System Check, keep the temperature below 35°C (95°F).
1. Clear DTCs (see DTC CHECK/CLEAR ).
2. Enter the following menus: Powertrain/Engine/Utility/Evaporative System Check/Automatic Mode.
3. After the Evaporative System Check is completed, check for pending DTCs by entering the following menus: Powertrain/Engine/Trouble Codes/Pending.
HINT:

If no pending DTCs are displayed, perform the MONITOR CONFIRMATION (see Diagnostic Help menu). After this confirmation, check for pending DTCs. If no DTCs are displayed, the EVAP system is normal.
PERFORM EVAPORATIVE SYSTEM CHECK (MANUAL MODE)

NOTE:
- In the Evaporative System Check (Manual Mode), perform the series of 5 Evaporative System Check steps manually using the Techstream.
- Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.
- Do not run the engine during this operation.
- 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 Evaporative System Check, keep the temperature below 35°C (95°F).
1. Clear DTCs (see DTC CHECK/CLEAR ).
