Monitor DTC Status
- Connect GDS to Data Link Connector (DLC).
- Ignition switch is turned "ON".
- Select "Diagnostic Trouble Codes (DTC)," and click "DTC Status" to check DTC information.
- Read the "DTC Status" parameter.
- Record all DTCs, DTC state and freeze frame data before clearing them. Is the DTC State "Present"?NOTE:
- History (Not Present) state: the DTC set but has been cleared.
- Present state: the DTC is active at present.
YES
- Go to next procedure.
NO
- This can be an intermittent fault caused by poor contact of the sensor and/or ECM connector. Or, ECM memory was not cleared after repair. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace the relevant component(s) as necessary, and go to "VERIFICATION OF VEHICLE REPAIR ".
