With Generic Scan Tool

DIAGNOSIS INSPECTION (NORMAL MODE)






MALFUNCTION INDICATOR LAMP (MIL) CHECK

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 abnormality in the system.

DIAGNOSTIC TROUBLE CODE (DTC) CHECK

NOTICE: (TOYOTA hand-held tester only): When the diagnosis system is switched from normal mode to check mode, it erases all DTC and freeze frame data recorded in normal mode. So before switching modes, always check the DTC and freeze frame data, and note them down.

1. Prepare the OBDII scan tool.





2. Connect the OBDII scan tool to DLC3 in the fuse box at the lower left of the instrument panel.

3. Turn the ignition switch ON and switch the OBDII scan tool switch ON.

4. Use the OBDII scan tool to check the DTC and freeze frame data, note them down.

5. Refer to Trouble Code Descriptions to confirm the details of the DTC.

Testing and Inspection

NOTICE: When simulating symptoms with an OBDII scan tool (excluding TOYOTA hand-held tester) to check the DTC, use normal mode. For codes on the DTC chart subject to "2 trip detection logic", turn the ignition switch OFF after the symptom is simulated the first time. Then repeat the simulation process again. When the problem has been simulated twice, the MIL lights up and the DTC are recorded in the ECM.
