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 level dipstick, oil filler cap sub-assembly, 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:
To prevent injury due to contact with an operating cooling fan, keep your hands and clothing away from the cooling fans when working in the engine compartment with the engine running or the power switch on (IG).
(a) Connect the GTS to the DLC3.
(b) Turn the power switch on (IG).
