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:
- TEST PASSED THIS IGNITION - Indicates whether a diagnostic test has reported a test passed this ignition cycle.
- TEST FAILED THIS IGNITION CYCLE - If a diagnostic test was performed and it was determined a fault existed during that ignition cycle, then the status will be indicated.
- TEST PASSED SINCE CODE CLEAR - Indicates a diagnostic test passed since the last time DTCs were cleared or the battery was disconnected.
- TEST FAILED SINCE CODE CLEAR - Indicates whether a diagnostic test has reported a fault since the last time DTCs were cleared or the battery was disconnected.
