Basic Inspection

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.

   Ensure engine stays below 1, 000 rpm.
