With Manufacturer's Scan Tool

Check the DTC

NOTE:
- If there is no DTC in the normal mode, check the 1st trip DTC using Continuous Test Results function (Mode 7 for SAE J1979) on the OBD II scan tool or hand-held tester.

- Hand-held tester only:
When the diagnosis system is switched from the normal mode to the check mode, all the DTCs and freeze frame data recorded in the normal mode will be erased. So before switching modes, always check the DTCs and freeze frame data, and note them down.

1. Prepare the OBD II scan tool (complying with SAE J1978) or hand-held tester.
2. Connect the OBD II scan tool or hand-held tester to the DLC3.
3. Turn the ignition switch ON, and push the OBD II scan tool or hand-held tester switch ON.
4. Use the OBD II scan tool or hand-held tester to check the DTCs and freeze frame data and note them down (For operating instructions, see the OBD II scan tool's instruction book).

If there is no DTC in the normal mode, check the 1St trip DTC using Continuous Test Results function (Mode 7 for SAE J1979) on the OBD II scan tool or hand-held tester.

5. See Trouble Code Descriptions to confirm the details of the DTCs.
