Will M.U.T.-III SE be used? 

YES >>: GO TO 2 

NO >>: GO TO  6

With M.U.T.-III SE

TESTING CONDITION:

Do not hold engine speed for more than the specified minutes below.

1. Start engine and warm it up to the normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Turn ignition switch ON.
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Start engine and keep the engine speed between 3, 500 and 4, 000 rpm for at least 1 minute under no load.
6. Let engine idle for 1 minute.
7. Select "DATA MONITOR" mode of "ENGINE" using M.U.T.-III SE.
8. Check that "COOLANT TEMP/S" indicates more than 70°C (158°F).

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

9. Open engine hood.
10. Select "SRT STATUS" mode of "ENGINE" using M.U.T.-III SE.
11. Rev engine up to 2, 500 to 3, 000 rpm and hold it for 3 consecutive minutes then release the accelerator pedal completely.
12. Check the indication of "CATALYST".

Which is displayed on M.U.T.-III SE screen?

CMPLT >>

GO TO  5

INCMP >>

GO TO 3

1. Wait 5 seconds at idle.
2. Rev engine up to 2, 500 to 3, 000 rpm and maintain it until "INCMP" of "CATALYST" changes to "CMPLT" (It will take approximately 5 minutes).

Does the indication change to "CMPLT"?
