How to reset the throttle idle speed after cleaning Buick?

Open KT300 or KT600 to enter the menu of selecting Buick series, and select 2008 (the production year is determined according to the 10 bit of the VIN code on the car). In the pop-up interface, select Buick series, with the fourth digit in the VIN code as "W", and select "W" to enter the vehicle type for further confirmation, with the fourth and fifth digits as "WT" and "WT LACROS". Select the eighth digit of the input VIN code as "X", select the engine and input it, select "mode quick setting" to enter the new interface, and select "idle reading reset" function. At this time, the interface will display the content of the data stream, and there are two buttons "Reset" and "Exit" below. After pressing the "Reset" button, the whole reset process can be completed within 1 second. Because the user didn't look at the data stream and pressed "reset" directly, he didn't see the fault data stream when he needed to reset, which is what we need to care about. Here, I write down the data flow of the normal operation of the engine after reset for your reference. I hope a friend will have the opportunity to collect the computer memory and dynamic data flow when the engine idle speed is too high after cleaning up the solar terms, which is helpful for maintenance!

Note: the "reset" function needs to be executed in the flameout state to succeed, and ECU only supports the brush writing function in the standby state!
