OBD PENDING TROUBLE CODE
- These appear when a problem is detected in a monitored system. The code for a failed system is stored in the PCM memory in the first drive cycle. This code is called the pending code. If the problem is not found in a second drive cycle, the PCM judges that the system returned to normal or the problem was mistakenly detected, and deletes the pending code (1DC). If the problem is not found in a second drive cycle, the PCM judges that the system returned to normal or the problem was mistakenly detected, and deletes the pending code when the ignition switch is turned to the ON position in the next drive cycle (2DC). If the problem is found in a second drive cycle too, the PCM judges that the system has failed, and the DTC is stored.
OBD ON-BOARD SYSTEM READINESS TEST
- This shows the OBD systems operating status. If any monitor function is incomplete, WDS or equivalent will identify which monitor function has not been completed. The Fuel system, Misfire and CCM are continuous monitoring-type functions. The HO2S, EGR system and Catalyst will be monitored under drive cycles. The OBD diagnostic system is initialized by performing the DTC cancellation procedure or disconnecting the negative battery cable.
OBD READ/CLEAR DIAGNOSTIC TEST RESULT
- This retrieves all stored DTCs in the PCM and clears the on-board readiness test results, freeze frame data, DTC and pending trouble code.
DIAGNOSTIC MONITORING TEST RESULTS
- The purpose of this test mode is to confirm the result of OBD-II monitor diagnostic test results. The result values stored when particular monitor is completed are displayed. If the monitor is not completed, initial value is displayed.
