Inspection Procedure

HINT:

According to the DATA LIST displayed by the OBD II scan tool or Hand-held tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of troubleshooting is one method to shorten labor time.

1. Warm up the engine.
2. Turn the ignition switch OFF.
3. Connect the OBD II scan tool or Hand-held tester to the DLC3.
4. Turn the ignition switch ON.
5. Push the "ON" button of OBD II scan tool or Hand-held tester.
6. Select the item "/DIAGNOSIS/ENHANCED OBD l l/DATA LIST/ALL (or ATM)".
7. According to the display on tester, read the "DATA LIST".
