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 Result function (Mode 7 for SAE J1979) or the hand-held tester or OBD II scan tool.

- Hand-held tester only:
When the diagnosis system is switched from normal mode to check mode, it erases all DTCs and freeze frame data recorded in normal mode. 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 DLC3 under the instrument panel lower pad.
3. Turn the ignition switch ON and turn the hand-held tester or OBD II scan tool switch ON.
4. Use the hand-held tester or OBD II scan tool to check the DTCs and freeze frame data, note them down. (For operating instructions, see the OBD II scan tool's instruction book.)
5. See step 4 to confirm the details of the DTCs.

NOTE:
- When simulating symptoms with an OBD II scan tool (excluding hand-held tester) to check the DTCs, use normal mode. For code on the DTC chart subject to "2 trip detection logic", perform the following either action.
- Turn the ignition switch OFF after the symptom is simulated the first time. 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.
