With Generic Scan Tool
Check for DTCsNOTE:
1. Prepare an 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 in the lower part of the instrument panel.
3. Turn the ignition switch ON and turn the OBD II scan tool or hand-held tester switch ON.
4. Use the OBD II scan tool or hand-held tester to check for DTCs and freeze frame data and write 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.
When simulating symptoms with the OBD II scan tool (excluding hand-held tester) to check the DTCs, use normal mode. For codes on the DTCs chart subject to "2-trip detection logic", turn the ignition switch OFF after the symptoms have been simulated the 1st time. Then repeat the simulation process again. When the program has DTCs they are recorded in the ECM.
