If simulation function of M-MDS is not used: 

  1. Start the engine.
  2. Remove the seal cover. (See SEAL COVER REMOVAL/INSTALLATION .)
  3. Disconnect the evaporative hose between the purge solenoid valve and the charcoal canister.
  4. 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:
  5. Set the vehicle on a dynamometer or chassis roller.
    WARNING:
    • When the dynamometer or chassis roller is operating, there is a possibility that the operator may come into contact with or be caught up in the rotating parts, leading to serious injuries or death. When performing work while the dynamometer or chassis roller is operating, be careful not to contact or be caught up in any of the rotating parts.
  6. Drive the vehicle at an engine speed to approx. 2000 RPM for 30 s or more.
  7. Put a finger to the purge solenoid valve and verify that there is no vacuum applied during Step  3.
    • If there is no vacuum, inspect the following:
    • If there is vacuum, inspect the following:
      • Evaporative hose (Purge solenoid valve-Charcoal canister)
