Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Confirmation Driving Pattern
HINT:
After a repair, check Monitor Status by performing the Key-Off Monitor Confirmation and Purge Flow Monitor Confirmation described below.
- KEY-OFF MONITOR CONFIRMATION NOTE:
- The Evaporative System Check (Automatic Mode) consists of 9 steps performed automatically by the GTS. It takes a maximum of approximately 40 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 start the engine during this operation.
- When the temperature of the fuel is 35°C (95°F) or higher, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature less than 35°C (95°F).
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for at least 30 seconds.
- Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode.
- After the "Evaporative System Check" is completed, check for All Readiness by entering the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P043E-00, P043F-00, P0441-7E, P0441-7F, P0446-72, P44673, P0450-11, P0450-15, P0450-2F, P1420-00, P1421-00, P1422-00, P1423-00, P1450-11, P1450-15, P1450-2A, P1450-2F, P2400-7E, P2400-7F, P2450-7E or P2451-7F.
- Check the DTC judgment result.
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system is malfunctioning.
- PURGE FLOW MONITOR CONFIRMATION (P0441-9C)
HINT:
Perform this monitor confirmation after the Key-Off Monitor Confirmation shows Complete.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for at least 30 seconds.
- Put the engine in Inspection Mode (Maintenance Mode).
- Start the engine and wait 15 minutes or more.
- Enter the following menus: Powertrain / Engine / Trouble Codes.
- Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P0441-9C.
- Check the DTC judgment result.
HINT:
- If the judgment result is NORMAL, the system is normal.
