BASIC INSPECTION: Special Repair Requirement

1. Check service records for any recent repairs that may indicate a related malfunction, or a current need for scheduled maintenance.
2. Open engine hood and check the following:
   • Harness connectors for improper connections
   • Wiring harness for improper connections, pinches and cut
   • Vacuum hoses for splits, kinks and improper connections
   • Hoses and ducts for leaks
   • Air cleaner clogging
   • Gasket
3. Confirm that electrical or mechanical loads are not applied.
   • Headlamp switch is OFF.
   • Air conditioner switch is OFF.
   • Rear window defogger switch is OFF.
   • Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature indicator points the middle of gauge.

5. Run engine at about 2, 000 RPM for about 2 minutes under no load.
6. Make sure that no DTC is displayed with CONSULT-III or GST.

Is any DTC detected? 

YES: GO TO 2.

NO: GO TO  3.

Repair or replace components as necessary according to corresponding Diagnostic Procedure.

: GO TO 3.

1. Run engine at about 2, 000 RPM for about 2 minutes under no load.
2. Rev engine (2, 000 to 3, 000 RPM) two or three times under no load, then run engine at idle speed for about 1 minute.
3. Check idle speed.

   Refer to "IDLE SPEED: SPECIAL REPAIR REQUIREMENT ".

   CVT: 650 ± 50 RPM (in P or N position)
