What must do after cleaning throttle body???

Firstly, we need to be clear that throttle body needs cleaning when the engine idle is rough, the engine stumbles through acceleration, or the Check Engine Light comes on. When road grime, carbon, and other materials embed in the components that make up the*throttle body, the vehicle's ability to efficiently burn fuel is reduced.

To clean the throttle body is pure manual and there are many instructions online, but what after that? You need to re-calibrate it, to let car computer know that the clean process is done. And in other cases, like power shut down, replace new throttle, replace related control units, all need re-calibrate/relearn.

The car in this case is Benz 2014 212chassis, itís throttle was just cleaned and need to do this process to stabilize engine idle.

1.Ignition is set to ON
2.Internal combustion engine
3.No operation on accelerator pedal
4.No CAN fault in traction system
5.Coolant liquid temperature between 5-100℃
6.Air intake temperature is not higher than 40℃

1.Choose the correct system path: ECM(Engine control module)-service function-stop learning throttle position
2.And the screen displays live data for engine rpm, coolant liquid temp., turbocharger boost sensor temp., gas paddle sensor
3.If any of the readings is not meeting the requirement, the tool wonít allow you to proceed
4.Tap OK on artimini to start throttle learning process and after a min, the process is completed.

Each car model and make has different way to do this, but I think the way to confirm if it succeed is to check engine idle.
