Inspection Procedure

HINT:

According to the DATA LIST displayed by the hand-held tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the 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 hand-held tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
4. Turn the ignition switch to the ON position.
5. Turn on the tester.
6. Select the item "DIAGNOSIS / ENHANCED OBD II / DATA LIST'.
7. According to the display on tester, read the "DATA LIST".
