Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Here is the drive cycle that needs done.It can be a little confusing but this drive cycle will ensure that all tests are run to pass emissions unless a fault occurs.

Cold Start
The barometric pressure (BARO) is more than 81 kPa.
The engine coolant temperature (ECT) is between (41-86°F).
The intake air temperature (IAT) is between (41-86°F).
The start-up ECT and IAT are within (16°F) of each other.
The battery voltage is between 9-16 volts.
The fuel level is between 15-85 percent.

Important: Whenever the ignition is turned ON, ignition positive voltage is supplied to the HO2S heaters. After verifying the enable criteria, turn OFF the ignition for approximately 5 minutes to allow the sensors to cool before continuing with the test. Once the engine is started, DO NOT turn the engine OFF for the remaining portion of the set procedure.

Turn OFF all of the accessories,
Set the vehicle parking brake.
Verify the transmission is in Park for automatic transmissions and Neutral for manual transmissions.
Start the engine and allow the engine to idle for 2 minutes.

Acceleration at part throttle to (55 mph) with this speed maintained until the engine reaches operating temperature. This may be up to 8 minutes depending on the start up coolant temperature.
Continued operation under these conditions for an additional 6 minutes.

Acceleration at part throttle to (45-55 mph) with this speed maintained for 2 minutes.
Deceleration to (0 mph).
Engine idling for 2 minutes while the following criteria is maintained:
The service brake is depressed.
The automatic transmission is in drive.
The manual transmission is in neutral with the clutch pedal depressed
