If simulation function of M-MDS is used

WARNING: This page is about a different variant/trim than selected.
  1. Start the engine.
  2. Disconnect the vacuum hose between the purge solenoid valve and the charcoal canister.
  3. Put a finger to the purge solenoid valve and verify that there is no vacuum applied when the engine is cold.
    • If there is a vacuum, inspect the following:
  4. Verify that the DTC P0443:00 is displayed. (See ON-BOARD DIAGNOSTIC TEST .)
    • If the DTC P0443:00 is shown, perform the DTC inspection. (See DTC P0443:00 .)
  5. Access the PCM PID EVAPCP using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .)
  6. Put a finger to the purge solenoid valve with Step 2 condition and verify that there is vacuum applied when set the present to 100 % duty value of the purge solenoid valve using the EVAPCP PID simulation function.
    • If there is no vacuum, inspect the following:
      • Increase the duty value of the purge solenoid valve to 50 % and inspect if the operation sound of the valve is heard.
    • If the operation sound is heard, inspect for loose or damaged vacuum hoses. (Intake manifold-Purge solenoid valve-Charcoal canister)
    • If the operation sound is not heard, inspect the purge solenoid valve. (See PURGE SOLENOID VALVE INSPECTION .)
  7. Warm up the engine to normal operating temperature.
  8. Monitor the EVAPCP PID using the M-MDS, and drive the vehicle approx. 2000 RPM  for 30 s or more.
