If simulation function of M-MDS is not used

Start the engine.
Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [VIN M (With Cylinder Deactivation)] .)
Disconnect the vacuum hose between the purge solenoid valve and the charcoal canister.
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:
  - Wiring harness and connectors (Purge solenoid valve-PCM terminal 1AW)
  - Purge solenoid valve (See PURGE SOLENOID VALVE INSPECTION [VIN M (With Cylinder Deactivation)] .)
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.
Drive the vehicle at an engine speed to approx. 2000 rpm for 30s or more.
Put a finger to the purge solenoid valve and verify that there is no vacuum applied during Step 2.
- If there is no vacuum, inspect the following:
  - Wiring harness and connector (Sub relay-Purge solenoid valve-PCM terminal 1AW)
  - Purge solenoid valve (See PURGE SOLENOID VALVE INSPECTION [VIN M (With Cylinder Deactivation)] .)
  - MAF, APP1, APP2, TP REL and LOAD PIDs (See PCM INSPECTION [VIN M (With Cylinder Deactivation)] .)
- If there is vacuum, inspect the following:
  - Vacuum hose (Purge solenoid valve-Charcoal canister)
