- Preliminary Inspection

All of the diagnostic procedures have specific conditions under which each test is to be performed. Basic conditions that apply to all tests are:

- Battery in good condition and fully charged.
- Adequate fuel in the fuel tank.
- Fuel is uncontaminated.
- Maintenance components in good condition (Fuel Filter, Air Filter, Spark Plugs, Ignition Timing, Positive Crankcase Ventilation System, Throttle Body Cleanliness).

Read each test procedure carefully to determine additional test conditions.
