With Generic Scan Tool

1. Prepare the OBD II scan tool (complying with SAE J1978).




2. Connect the OBD II scan tool to DLC3 under the instrument panel lower pad.
3. Turn the ignition switch ON and turn the OBD II scan tool switch ON.
4. Use the OBD II scan tool to check the DTCs and freezed frame data; note them down. (For operating instructions, see the OBD II scan tool's instruction book.)
5. See "Trouble Code Descriptions" to confirm the details of the DTCs.

NOTE:
- When simulating symptoms with an OBD II scan tool (excluding TOYOTA 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.
