节气门的基本设定（Basic settings of throttle valve）

节气门的基本设定（Basic settings of throttle valve） 节气门的基本设定(Basic settings of throttle valve) The basic setting about solar term door 1 why should the basic settings Read the data stream, will find that when the throttle valve is dirty, the engine at idle, solar term door opening will increase. This is because the throttle body is dirty, the opening under the same air intake will be reduced, will not be enough to maintain the rated speed of the engine, the door will increase the solar term (IAC); cleaning solar term door, idle throttle opening will reduce. This shows that the electronic control unit has the function of learning. Not only can check to change the component parameters, but also can adapt to this change. However, the electronic control unit is how to know the initial parameters of the component? This requires the basic settings, before doing the basic settings, if the control unit received a solar term door voltage signal of the idle position, but do not know the opening angle, this is because the control unit does not know the voltage minimum idle position, the largest solar term door idle position the value of such basic parameters. If the control unit knows the minimum idle position of maximum solar term door, the idle position, know the voltage range of the solar term door idle potentiometer, if the voltage control unit that the middle position of several values of the solar term door idle potentiometer will know the characteristics of the solar term door speed potentiometer. So, when the control unit receives the signal voltage at any location, you can judge the throttle opening. The basic setup is to let the ECU understand the basic characteristics of basic parameters, throttle valve, adjust it with the door will automatically move solar term in the later operation process. 2 basic set of channels The basic setup refers to artificially create a specific initial state, both for process fault diagnosis instrument command control unit to do a basic set, it consists of an electronic control unit, not artificial interference. The basic settings using the same instrument, why different types of basic set of channels is not the same? The original basic settings of this function depends on the instrument, but the basic set of channels depends on the electronic control system using software. Vehicle electronic control system channel Audi 200/V6 (BOSCH) 001 Audi 200/1.8T (BOSCH) 098 The red flag SIEMENS noblige SIMOS-4S 001 Jetta Dr. 5V (BOSCH) M3.8.2 098 Jetta 2V SIEMENS SIMOS-3W 060 The 3 basic action element set Careful the repairman might have heard the basic settings, the throttle body generate dada sound, can see the solar term door in jitter. This is driving in the throttle body in the solar term door idle motor under the following actions: Close from the initial position to the minimum position, and then from the lowest position is opened to the maximum position, finally return to the initial position. At this time, the electronic control unit will be the biggest, the smallest three equal position between both maximum and minimum record down. This identifies the characteristics of the electronic control unit for throttle valve. 4 in what circumstances to carry out the basic set From the above analysis principle, the factors of electronic control unit and the throttle body coordination in effect when the need for basic settings. (1) in the replacement of the electronic control unit, control unit has no storage characteristics of the throttle body, need the basic settings. (2) in the electronic control unit ECU memory power, memory loss, need the basic settings. (3) the replacement of the throttle body, need the basic settings. (4) replacement or disassembly inlet, affect the electronic control unit and the throttle body to coordinate the work of both the idle control of basic settings. (5) in the cleaning of the throttle body, idling characteristics potentiometer does not change solar term door opening, but in the same solar term door, air intake has changed the idle speed control characteristics have changed to the basic settings. 5 what are the consequences of the basic settings The repair or replacement of the parts, if not for the basic set, the electronic control unit and idle control components will not work coordination, performance is the idle speed control is not accurate, unstable, such as idle call shouting bottom, unstable idle speed. But this poor performance is temporary, This is because the ECU has learning and automatic adaptation function. This is just to learn and adapt to the basic setting process as fast and accurate. Some models for repair or replacement of parts above, not only to the basic settings, but also remove the original learning value. This is related to the software models. For example, the car Jetta vanguard in cleaning solar term door, if only the basic settings, the engine idle speed will be high, this is because the electronic control unit also memory idle original throttle opening value. Use the function of VAG1551 10, the nature of channel 00, the execution of the clear learning value functions, the engine idle speed normal.
