With Generic Scan Tool

INSPECT DIAGNOSIS (Normal mode)




a. Check the MIL
1. The MIL turns on when the ignition switch is turned ON and the engine is not running.

HINT: If the MIL does not turn on, troubleshoot the combination meter.

2. When the engine is started, the MIL should turn off. If the lamp remains on, the diagnosis system has detected a malfunction or abnormality in the system.




b. Check for DTCs

NOTE:
Hand-held tester only:
When the diagnosis system is changed from normal mode to check mode, all DTCs and freeze frame data recorded in normal mode will be erased. Before changing modes, always check DTCs and freeze frame data and make a note of them.

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 press the OBD II scan tool or hand-held tester switch ON.
4. Select the item "DIAGNOSIS/ENHANCED OBD II/ DTC INFO/CURRENT CODES".
5. Use the OBD II scan tool or hand-held tester to check for DTCs and freeze frame data and write them down (see the instruction manual for the OBD II scan tool or the hand-held tester).
6. See DTC Chart to confirm the details of the DTCs.

NOTE: When simulating symptoms with OBD II scan tool (excluding hand-held tester) to check the DTCs, use normal mode. For DTCs subject to "2 trip detection logic", 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 illuminates on the instrument panel and DTCs are recorded in the ECM.
