EMISSION CONTROL SYSTEM ON-VEHICLE INSPECTION

PROCEDURE

1. VISUALLY INSPECT HOSES, CONNECTIONS AND GASKETS

   
   

   1. Inspect the hoses and gaskets for scratches, cracks or air/oil leaks from the connecting parts.

      Tech Tips

      If the hoses or gaskets are damaged or some of the connections are loose, they may cause an engine stall or malfunction.

2. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM

   
   

   1. Connect the GTS to the DLC3.

   2. Disconnect the fuel vapor feed hose from the purge VSV.

      Note

      
      

      • Remove any dirt or foreign matter on the fuel tube connector before performing this work.

      • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the fuel tube connector has an O-ring that seals the pipe.

      • Perform this work by hand. Do not use any tools.

      • Protect the disconnected parts by covering them with plastic bags after disconnecting the fuel vapor feed hose.

   3. Put the engine in inspection mode (maintenance mode) Click here.

   4. Turn the power switch on (IG).

   5. Turn the GTS on.

   6. Enter the following menus: Powertrain / Engine / Active Test / Activate the VSV for Evap Control.

   7. Check that vacuum occurs at the purge VSV port.

   8. If vacuum does not occur, check the following items:

      
      

      • Purge VSV (for canister purge)

      • Clogs in the fuel vapor feed hose connecting the intake air surge tank and purge VSV

      • Voltage from the ECM PRG terminal Click here

      Exit Active Test mode and reconnect the fuel vapor feed hose.

      Note

      
      

      • Check that there are no scratches or foreign matter around the connecting parts of the fuel tube connector and pipe before performing this work.

      • Connect the fuel tube connector and push the retainer in until the retainer makes a "click" sound to lock the claws of the retainer.

      • After connecting the fuel vapor feed hose to the fuel tube connector, check that the fuel vapor feed hose is securely connected by pulling on the fuel tube connector and the fuel vapor feed hose.

   10. Enter the following menus: Powertrain / Engine / Data List / EVAP Purge VSV.

   11. Warm up the engine and drive the vehicle.

   12. Confirm that the purge VSV opens.

       If the result is not as specified, replace the purge VSV, wire harness or ECM.
