Turn off or rest check engine light to pass smog

It takes at least one "Good trip" stored in the computer before it will pass a smog check. Simply resetting the light did not fix the problem that caused the light to come on to begin with, and attempting to smog it will only result in a failed test.
You must address the fault first, then reset the system and drive upwards of 150 miles before a "Good trip" has been stored in the computer.

Hesitation when accelerating from rest

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

How can rest the computer alarm manualy to cancel the fualty alarm like engine service soon

A check engine light usually isn't a faulty alarm. You should have the computer scanned and the cause for the light to come on repaired. However, disconnecting the battery will usually clear the code.
