Diagnostic Trouble Code Descriptions

Fig. 3 Diagnostic Codes & Priority Chart:

Each fault code has its own pinpoint test. These tests have priorities assigned with ``1'' being the highest priority and ``4'' being the lowest. One fault code may cause other fault codes to be displayed. Perform pinpoint tests in order of priority starting with the highest. For Diagnostic Codes, refer to Fig. 3. For Connector Terminal Identification, refer to SCHEMATIC DIAGRAMS/ELECTRICAL AND ELECTRONIC DIAGRAMS. For Pinpoint tests, refer to DIAGNOSTIC CHARTS.

NOTE: For code 13, this circuit originates at a 30 amp fuse in the power distribution box. Check the fuse.
