SERVICE INFORMATION




















The diagnostic tables are designed to be used as a supplement to Service Manual trouble diagnostic procedures. The tables take advantage of CONSULT to broaden the diagnostic process and make it more efficient. The points below highlight some of the advantages and details of using the tables to supplement Service Manual diagnosis.

^ The Basic Inspection procedure now includes a Fuel Pressure Check, CONSULT Function Test, and a reorganized CONSULT Diagnostic procedure.

^ Shaded items in boxes are the recommended CONSULT diagnostic procedures.

^ Items in bold print with three *** asterisks indicate that an additional diagnostic procedure has been added to the Service Manual diagnostic procedure.

^ Items continue to be selected by Service Manual, symptom-related diagnostics.

^ Additional items have been inserted that previously have not been listed in the Service Manual for symptom-related diagnostic procedures.

^ The information is a quick-reference supplement for the Service Manual. The Service Manual should continue to be the primary source of information for trouble diagnosis.

^ Individual Diagnostic Procedures 21-45 may indicate that the Service Manual should be referenced for additional diagnostic information.
