Quick Test: Notes
The QUICK TEST diagnostic procedure is a functional test of the EEC-IV system. It consists of 4 basic test steps. These basic steps must be carefully followed in sequence, otherwise misdiagnosis, or replacement of non-faulty components may result.
- PREPARATION FOR TESTING and EQUIPMENT HOOK-UP.
- KEY ON ENGINE OFF (KOEO) SELF-TEST.
- KEY ON ENGINE RUNNING (KOER) SELF-TEST.
- CONTINUOUS SELF-TEST.
After all tests, servicing, or repairs have been completed, repeat QUICK TEST to ensure all EEC-IV systems work properly.
The KOEO and KOER SELF-TESTS are intended to detect faults present at the time of testing, not intermittent faults. Intermittent faults are detected by CONTINUOUS SELF-TEST and stored in the ECA memory.
NOTE:
Correct test results for system are dependent on the correct operation of several related non-EEC components and systems. All non-EEC problems should be corrected before attempting to diagnose the EEC system.
