DTC Test Descriptions

DTC TEST DESCRIPTIONS
The self-diagnostic tests run to determine if a subsystem has passed or failed a specified test. After a test is performed the PCM will record test PASS/FAIL criteria for display with a Scan tool. Each DTC will have three records and are as follows:
- LAST TEST - Indicates whether the diagnostic reported a test passed or failed the last time it ran. (Even if it was not this ignition cycle.)
Possible Display: PASSED, FAILED, NOT RAN
- THIS IGNITION - Indicates if the diagnostic test has run this ignition cycle and the results of that test(s).
Possible Display: PASSED, FAILED, PASS & FAIL, NOT RAN
- SINCE CLEAR - Indicates if diagnostic test has run since DTCs were cleared and the results of that test(s).
Possible Display: PASSED, FAILED, PASS & FAIL, NOT RAN, HISTORY
