With Generic Scan Tool

Check the DTC

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

1. Prepare the OBD II scan tool (complying with SAE J1978) or the hand-held tester.
2. Connect the OBD II scan tool or the hand-held tester to DLC3 under the instrument panel lower pad.
3. Turn the ignition switch ON and turn the OBD II scan tool or the hand-held tester switch ON.
4. Use the OBD II scan tool or the hand-held tester to check the DTCs and freezed frame data, 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 the continuous Test Results function (Mode 7 for SAE J1979) or the OBD II scan tool or the hand-held tester.

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

NOTE:
When simulating symptoms with an OBD II scan tool (excluding the hand-held tester) to check the DTCs, use normal mode. For code on the DTC chart subject to "2 trip detection logic", perform either of the actions.
- Turn the ignition switch OFF after the symptom is simulated the 1st 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.
