DTC Check (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 started, the MIL should go off. If the lamp remains on, the diagnosis system has detected a malfunction or abnormality in the system.

b. Check the DTC.

NOTE:
- If there is no DTC in the normal mode, check the 1st trip DTC using Continuous Test Results function (Mode 7 for SAE J1979) on the TOYOTA hand-held tester.
- TOYOTA hand-held tester only: When the diagnosis system is switched from the normal mode to the check mode, it erases all DTC and freezed frame data recorded in the normal mode. So before switching modes, always check the DTC and freezed frame data, and note them down.

1. Prepare TOYOTA hand-held tester.




2. Connect the TOYOTA hand-held tester to the DLC3 at the lower center of the instrument panel.
3. Turn the ignition switch ON and push the TOYOTA hand-held tester switch ON.
4. Use the TOYOTA hand-held tester to check the DTC and freezed frame data and note them down (For operating instructions, see the OBD II scan tool's instruction book.).
If there is no DTC in the normal mode, check the 1st trip DTC using Continuous Test Results function (Mode 7 for SAE J1979) on the TOYOTA hand-held tester.
5. See "Trouble Code Descriptions" to confirm the details of the DTCs.
