With Manufacturer's Scan Tool

Check the DTC

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

- 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 normal mode will be erased. So before switching modes, always check the DTCs and freeze frame data, and note them down.

1. Prepare the hand-held tester or OBD II scan tool (complying with SAE J1978).
2. Connect the hand-held tester or OBD II scan tool to the DLC3 at the lower left of the instrument panel.
3. Turn the ignition switch ON and push the hand-held tester or OBD II scan tool main switch ON.
4. Use the hand-held tester or OBD II scan tool 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 normal mode, check the 1st trip DTC using Continuous Test Results function (Mode 7 for SAE J1979) on the hand-held tester or OBD II scan tool.

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

NOTE:
- Turn the ignition switch OFF after the symptom is simulated once. Then repeat the simulation process again. When the problem has been simulated twice, the MIL lights up and the DTCs are recorded In the ECM.
- Check the 1st trip DTC using Mode 7 (Continuous Test Results) for SAE J1979.
