With Generic Scan Tool

DTC CHECK (Normal Mode)

NOTE:
- If there is no DTC in the normal mode, check the pending fault code using the Continuous Test Results function (Mode 7 for SAE J1979) on the OBD II scan tool or the hand-held tester.
- 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 the normal mode will be erased. So before switching modes, always check the DTCs and freeze frame data, and then write them down.




a. Checking DTCs using the hand-held tester or OBD II scan tool.
1. Connect the hand-held tester or the OBD II scan tool to DLC3.
2. Turn the ignition switch ON.
3. Use the hand-held tester or the OBD II scan tool to check the DTCs and freeze frame data and then write them down. For the hand-held tester, enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES. For the OBD II scan tool, see its instruction manual.
4. See Trouble Code Chart to confirm the details of the DTCs.

NOTE: When simulating a symptom with the OBD II scan tool (excluding hand-held tester) to check for DTCs, use the normal mode. For DTCs subject to "2 trip detection logic", perform either of the following actions.

- 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 pending fault code using the Continuous Test Results function (Mode 7 for SAE J1979) on the OBD II scan tool.

b. Clearing the DTCs using the hand-held tester or the OBD II scan tool.
1. Connect the hand-held tester or the OBD II scan tool to the DLC3.
2. Turn the ignition switch ON.
3. Erase DTCs and freeze frame data using the handheld tester or the OBD II scan tool (complying with SAE J1978).

For the hand-held tester: 1) enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CLEAR CODES; and 2) press YES. For the OBD II scan tool, see its instruction manual.
