5. Turn the ignition switch off.

6. Disconnect the Techstream.

7. Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.

8. Connect the cable to the negative (-) battery terminal.

9. Connect the Techstream to the DLC3.

10. Turn the ignition switch to ON and turn the Techstream on.

11. Wait 30 seconds or more.

12. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

13. Read the DTCs.

HINT
- If a DTC is output, the system is malfunctioning.
- If a DTC is not output, perform the following procedure.
