Diagnosis (Normal Mode)

INSPECT DIAGNOSIS (Normal Mode)




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

HINT: If the MIL does not light up, troubleshoot the combination meter.

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

b. Check the DTC.

NOTE: 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 make a note.




1. Connect the scan tool (OBD II scan tool or hand-held tester) to the DLC3.
2. Turn the ignition switch ON and turn the scan tool switch ON.
3. Use the scan tool to check the DTCs and freeze frame data and make a note (For operating instructions, see the scan tool's instruction book).
4. See Trouble Code Descriptions to confirm the details of the DTCs.

NOTE: When simulating symptoms with the OBD II scan tool (excluding hand-held tester) to check the DTCs, use the normal mode. For codes on the DTCs chart subject to the "2 trip detection logic", turn the ignition switch off after the symptoms have been simulated the 1st time. Then use the simulation process again.
