Test Results & Action To Take
- If no codes appear, repeat SELF-TEST and verify that no service codes are present, and then go to CIRCUIT TEST NN . If code 98 and any other code appears, perform KEY ON/ENGINE OFF SELF-TEST and obtain a Code 11 for KEY ON/ENGINE OFF portion of QUICK TEST .
- If engine ID code is 2, 3 or 4 (20, 30 or 40 with STAR tester), and code 11 is displayed, ENGINE RUNNING SELF-TEST portion is okay. If symptom was of an intermittent nature, go to CONTINUOUS SELF-TEST . If symptom is present, go to DIAGNOSIS BY SYMPTOM TEST . Otherwise QUICK TEST is complete, and EEC-IV system is okay.
- If engine ID code is 2, 3 or 4 (20, 30 or 40 with STAR tester), and any code other than 11 appears, ENGINE RUNNING SELF-TEST portion is at fault. Perform the test indicated in the ENGINE RUNNING SELF-TEST table for that specific engine.
- Start with the first code displayed. If the tests refer you to other checks, perform them as instructed. When more than one code is displayed, repair problems in the order that codes are displayed. Whenever a repair is made, repeat QUICK TEST .
