3. Turn ignition switch OFF and wait at least 10 seconds.
4. Start engine and keep the engine speed between 3, 500 and 4, 000 rpm for at least 1 minute under no load.
5. Let engine idle for 1 minute.
6. Check that "COOLANT TEMP/S" indicates more than 70 deg.C (158 deg.F).

   If not, warm up engine and go to next step when "COOLANT TEMP/S" indication reaches to 70 deg.C (158 deg.F).

7. Open engine hood.
8. Select "DTC& SRT CONFIRMATION" then "SRT WORK SUPPORT" mode of "ENGINE" using CONSULT.
9. Rev engine up to 2, 000 to 3, 000 rpm and hold it for 3 consecutive minutes then release the accelerator pedal completely.
10. Check the indication of "CATALYST".

Which is displayed on CONSULT screen?

CMPLT

GO TO 4.

INCMP

GO TO 3.

With CONSULT

1. Wait 5 seconds at idle.
2. Rev engine up to 2, 000 to 3, 000 rpm and maintain it until "INCMP" of "CATALYST" changes to "CMPLT".
   NOTE: It will take approximately 5 minutes.

   If "CMPLT" is not displayed after 5 minutes, turn ignition switch OFF and cool down the engine. Retry from step 1 when "COOLANT TEMP/S" indication reaches to 70 deg.C (158 deg.F).
