The diagnosis circuit of Daewoo ESPERO fault code of 14

Published:2011/5/18 1:54:00 Author:Borg | Keyword: diagnosis circuit, Daewoo ESPERO

The diagnosis circuit of Daewoo ESPERO fault code of 14

The code of 14 means that that the signal voltage of coolant temperature sensor is low--indicating high temperature(see as Figure 4 and Figure 16). The coolant temperature sensor controls the ECM signal with a thermistor. Firstly , ECM imposes a voltage on the sensor in No.410 circuit, when the engine becomes cool, the resistance of the sensor(thermistor) is getting high, then ECM will detect a high signal voltage. When the engine is getting hotter, the resistance of the sensor is becoming low, the voltage is coming down. When at the normal engine temperature, the ECM pin of C10 will get the voltage of 1.5~2.0V. (View)

wide range timing switch circuit

Published:2011/5/19 1:20:00 Author:TaoXi | Keyword: wide range, timing switch

The wide range timing switch circuit This circuit uses the monolithic time transmitter circuit XR2242, the timing range is from few milliseconds to few days. This circuit is composed of a time-based oscillator, a 8-bit binary counter and a control trigger. The time-base circuit is composed of the resistor R and capacitor C, there are three kinds of output pulse time: T=RC (pin 8), T=2RC (pins 2) and T=128RC (pin 3). Through the additional voltage, we can make the output automatic reset. By using the positive edge of the trigger input port pulse, we can start the time process. (View)

The new generation touch stepless light and speed adjustment circuit NB7232

Published:2011/5/18 3:47:00 Author:TaoXi | Keyword: new generation, touch, stepless, light and speed adjustment

Related components PDF download: NB7232 The basic working principle of the circuit (dimming example): the human body electricity and the city electricity have the same frequency, when the human body touches the touch tablet, the body electricity becomes the standard MOS electrical level with the wave cutting, the amplification and the reshaping of the input buffer stage. When the touch duration is more than 32ms and less than 332ms, the logic control part circuit is in the switching working state. When the touch duration is more than 332ms, the logic control part circuit is in the dimmer working state, the output trigger pulse phase angle continuous cyclical changes between the 41 degrees to 159 degrees, and according to the human eye sensibility, there are three processes: the fast process, the slow process and the intermittent process.

The air-bag and seatbelt control circuit of Buick-Century
The air-bag is a kind of negative protection equipment, when the car is crashing with others in the running way, the sensor receives an impact signal, as long as it reaches a supposed degree, the sensor will generate a signal and send it to the controller, then the electric controller will compare it with the saved data. If it reaches the condition of opening the air-bag, the drive circuit will send a starting signal to the air generator of the air-bag module, and the generator will explode the gas-forming admixture and swell the air-bag.

The ground connections of Buick-Century (see Figure 1,2,3)

Published:2011/5/18 3:22:00 Author:Borg | Keyword: ground connections, Buick-Century

These years, it is the common point of importing car circuits to explicitly describe the ground connections of electric equipment, as the car electric equipment is fixed throughout the car, and many general parts are fixed on metal slides and shaking engines or brackets, so its not dependable to connect in a single line. It is necessary to link all the ground connections into a reliable net with the negative point of the battery, which is also convenient to detect partial faults. The following shows the chief ground connections: The ground connections of Buick-Century (1) (View)
