- 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, Spark Plugs, PCV System and throttle body cleanliness.)

Read each test procedure carefully to determine additional test conditions.
