ON-VEHICLE INSPECTION

CAUTION / NOTICE / HINT

CAUTION:

When working near the engine room while the engine has started or the power source mode is ignition switch to ON (IG), do not touch the fan and generator V belt or rotating components such as the fan, etc.
Touching the fan and generator V belt or rotating components such as the fan, etc. could result in your hand or clothing getting caught and pulled in.

PROCEDURE

1. VISUALLY INSPECT HOSES, CONNECTIONS AND GASKETS

(a) Visually check that the hoses, connections and gaskets have no cracks, leaks or damage.

NOTICE:

Detachment or other problems with the engine oil dipstick, filler cap, ventilation hose or other components may cause the engine to run improperly.
Air suction caused by disconnections, looseness or cracks in any part of the air induction system between the throttle body assembly and cylinder head sub-assembly will cause engine failure or engine malfunctions.

If any defects are found, replace parts as necessary.

2. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM

CAUTION:

When working near the engine room while the engine has started or the power source mode is ignition switch to ON (IG), do not touch the fan and generator V belt or rotating components such as the fan, etc.
Touching the fan and generator V belt or rotating components such as the fan, etc. could result in your hand or clothing getting caught and pulled in.

(a) Connect the GTS to the DLC3.

(b) Start the engine.

(d) Turn the GTS on.

(e) Slide the clip and disconnect the fuel vapor feed hose from the purge valve (purge VSV).

(f) Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the EVAP Purge VSV.

Powertrain > Engine > Active Test

(g) Check that vacuum occurs at the purge valve (purge VSV) port.

(h) If vacuum does not occur, check the following items:

Purge valve (purge VSV)
Clogs in the fuel vapor feed hose that connects the intake manifold and purge valve (purge VSV)
Voltage from the ECM PRG terminal
