Car Key Programmer
Now the car will be equipped with a remote control key and a mechanical key, but most of the features of the car keys are the same. Just make all kinds of!
The lost car keys is a very troublesome thing, spare keys can be used normally, but relatively little car keys and high-end security is, if we want to match the remote control key, (not cheap car hundreds of car, do not have to say) 4S shop to a new “code” the key and the original car to match. The matching is completed, the new key can be enabled, then lost key failure, even if someone picked up your old keys, he also can you open the door by mechanical lock mode, but not likely to start your vehicle. Therefore, the security level of this code has become a major factor in determining the price level. But then a lot of people will be worried, can open my car door is not safe, ah, there is no more secure way to do. Of course, just as the replacement of the lock core, the most rigorous approach is to replace a whole car lock, so the person who picked up your keys will not even enter the door. Help car said the master key:
The vehicle start key: in general, according to the two and second long press this button, the vehicle will start, but there are also many models have started in different ways, such as the first press the unlock button car keys, and then press the lock button, press the start button at the vehicle, the car will start. Of course, this design is also used to prevent the false press the vehicle start button.
Car key trunk key: in the case of the car lock, long press the trunk key of the car keys, the trunk can not trigger the normal opening of the security system. (some models are continuously press two) if the car keys left in the trunk inside, and then closed it? Some models do the design to prevent this situation, if you are lucky, the trunk door induction to the car keys in the trunk, is not closed, if you bad luck, not only the prevention function, pulled out a mechanical key to you, to open the trunk.
Intelligent key keyless start system of induction to the intelligent key: when you press the start button keyless vehicle does not start, the intelligent key near the keyless start button, press the button again, the vehicle will start.
This is because the smart key inside a battery coil, can emit microwaves, and the start button and there was a battery coil, receiving microwave transmitted to the ECU, the ECU analysis key intelligence is not belong to this car, if it is, the vehicle will start.
Of course, there is also the need to explain some of the vehicle battery coil not and keyless start button together, some are in the armrest box, some are in the centre console, so look your car manual.
Car keys to unlock or lock the vehicle failure, how to use?
When the car keys without electricity or disturbed by other signals and cannot unlock or lock when the car keys near the vehicle antenna, press the unlock button or the lock button, the signal selector will receive preferential signal the car keys to unlock or lock.
In general, because the vehicle signal selector are installed in the preferred car near the antenna, so will the car keys to unlock or lock near here, even if the key battery or by other signal interference, can receive weak signal instructions.
If it is not, then can only come up with a mechanical key out of the solution / locked.
Some of the car keys have a red horn button, you have not studied what is the use of?
A according to the key, the car is far from the car park in a corner of the mad called up??????????????????????? It has to find a car and help function, when the suspect has the bad guys near, you can let the car continued to sound horn, causing others to pay attention to.
However, in the middle of the night in the silence of the underground garage, the horn sounded really disturbing too.
Where is the mechanical key of the intelligent key?
Equipped with intelligent key models, in general, the mechanical keys are hidden inside the smart key inside, there are folding, mosaic, and knob type, etc..
Remote control window: this function, there is seasonal (summer) is particularly practical: the hot sun in the car inside the hot ah! If you can find a cool place in the car nearby, let the window open or hot air to get on the bus, how good! Of course, some luxury models, there is a remote control to start the engine and even the air-conditioning function???????????. Try, long press the unlock button for a few seconds, the 4 windows are not open it?
Special remind, because the view of the reasons, some manufacturers of the mechanical key hole on the door handle to hide, so the use of mechanical keys to cover the door handle to open.
Some of the above is the car keys and car keys secret “deal with method of some special cases, multi-function car key in the convenience of our life, but also brings some problems for us, because every coin has two sides, so some owners do not have to have friends over some functions and trouble because, each car keys in the beginning of the design, are considering all aspects of the problem, at least in the problems of maintenance fees, can give you a lot of the rest.
And you can go to GO2OBD.NET choose a car key programmer for your car .
there’re have professional car key programmer and universal car key programmer.

One: car fault diagnosis of the four basic principles:
(a) after the first simple, easy to post difficult principle
(two) the principle of first thought, after the first ripe
(three) first, after the first, after the first outside the principle of
(four) the principle of first use, code first
Two: the basic method of automobile fault diagnosis:
1, ask the user: the time of failure, the phenomenon, the situation at that time, the causes of failure and whether the maintenance, disassembly, etc..
2, initially determine the scope and location of the fault.
3, call up the fault code, and find out the contents of the fault.
4, according to the fault code display the scope of the fault, maintenance, especially pay attention to whether the joint is loose, fall off, the wire connection is correct.
5, overhaul is completed, should verify whether the fault has been ruled out.
6, such as the adjustment of the fault code, or check out after the failure of the content, according to the fault phenomenon, roughly determine the scope of the fault, the use of the performance of the method to check one by one to exclude.

Mercedes Benz MB Star C3
In winter on hard and slippery, if the tire maintenance, your car will likely understeer and braking distance is too long is not sensitive traffic safety brake. In the winter before you should first focus on the tire, we recommend that you usually best to keep every two weeks to check the tire pressure correction of good habits. Come with the study of the small series to learn BMW car maintenance knowledge!
1 question: ask the BMW car maintenance cycle is how many kilometers to save money and does not hurt the car?
Answer: BMW’s original design, the production of different periods and different models of BMW’s maintenance of the intervals are not the same. As of model year 1995 740iL/E38 the oil change intervals around each traveling 10000 kilometers. The 2005 section of the 740Li/E66 of the oil change interval about every more than 20 thousand km (the number of kilometers are just a reference, the actual mileage is the car computer BMW according to the working condition of the engine and automatically calculate the different. As for the oil sporty driving style time and warm type driving style oil change ahead of time). In our work experience, in the general driving in the territory of China in the use of the use of BMW suggested that the interval between the driver for the oil in about 10000 kilometers per ride. As you know, some of the current domestic gasoline quality can not meet the international standard, while the engine at work, some of the chemical composition of gasoline will be channeling into the oil, thereby affecting the stability of oil. In our daily work occasionally encounter some engine with thick sludge precipitation. There are reasons for this relationship between the quality of sludge generated with the usual maintenance interval oil and gasoline, oil and the inferior quality and of course add oil also has a relationship.
2 problem: some BMW owners even in finished tire maintenance (fill tire or plus end gas), the instrument still display tire alarm?
A: in order to improve driving safety, E60, E90 and part of the E66 BMW car system has a tire leak alarm. In the vehicle if there is a flat tire or pressure is not enough, there are warning lights and warning sound at the same time to remind motorists on the meter, when the fill tires or the corresponding tires after gas, must be on the tire pressure detection system to initialize the system set up, otherwise, even if the tyre pressure reaches the standard. Tire warning lights are still burning. Different models of the BMW car initialization procedures are not the same. In the owner’s manual can be found in the corresponding models of the initial set up procedures.

Car Central Controller
ECU central controller (ECU) is one of the basic functions of cruise control system of automobile cruise control system of automobile drivers according to road conditions selected speed, switch to start the fixed cruise system to replace the throttle pedal control through point. According to the influence of the ramp, traffic of speed, automatic adjustment of supply vehicles to realize automatic cruise control. According to the driving procedures, automatic lift cruise control function when the clutch pedal is stepped gear transmission or stepping on the brake pedal, the accelerator pedal control recovery, without adding any extra action. The clutch pedal, brake pedal or arbitrary switch three operation modes in a way can cancel the car cruise control function, safe and reliable. Manual acceleration or deceleration: command switch consists of 3 buttons: “speed” and “acceleration” and “deceleration”. Point moving speed (or slow) button, the speed will continue to increase (or slow), stop moving, the speed of the speed control system is set to set the speed. The short-time speed automatic recovery in automatic control of cruise control system can be directly to the pedal pedal speed, release the original set cruise speed automatic recovery. Automatic memory: according to the selection of speed, automatic memory. In the processing point by the road brake, step down the clutch operation action, automatic lift cruise control system. Move the recovery button, on the basis of automatic memory, automatically restore the original setting speed per hour. Cruise control structure for cruise control system (the system) is composed of a sensor, a central controller (ECU), servo controller, switch and display instructions, according to the driving command instead of automatic cruise control function to realize the automobile pedal. Central controller (ECU) is the center of the speed control system, according to the most stable acceleration design of each model to determine. ECU according to the instruction speed, the actual speed and other input signals, after the CPU data processing output signal driven servo controller to control the engine throttle opening degree. For sensor signal detection and acquisition speed, the output signal of direct feedback to the ECU instruction, lock the door opening and adjust the solar term, according to the signal from the lifting of the brake pedal, clutch pedal or instructions to switch at any point, release the lock. According to the ECU instructions to adjust the solar term door was the door of the solar term, “lock”, when the car resistance increases (uphill) and speed reduction, control solar term door opening increases and decreases, to keep the bus speed and move speed instruction execution. 1 what is the automobile cruise? Cruise is to replace the pedal by using microcomputer technology, realize the automatic adjusting device of throttle, speed of the car. Through the manual button to increase, reduce the speed instead of a long time foot pedal, driving easy. Cruise is easy to drive, the car, fuel-efficient, utility function. In Europe and Japan and other developed countries, 70% of the cars are equipped with cruise control system. What is the basic function of 2 Lutan cruise control unit? Start: after the speed stability, point to move the set / deceleration key (SET/decel), set the speed. Recovery: with automatic memory function, cruise lift, move the restoration / accelerator (RES/accel), to restore the original speed. Release: release point (Cancel) key, lift the cruise, the clutch pedal, the brake pedal can lift cruise. Manual acceleration and deceleration: in constant speed condition, move the set / speed button (SET/decel) every time, deceleration 2 kilometers, move the recovery / accelerator (RES/accel), each 2 km speed. 3 the use of cruise control would not affect the safety? This is a lot of untouched cruise people have doubts. Cruise abroad has long been widely used, safety is guaranteed, even if the cruise for their failure is only constant failure, restore pedal control, without any negative impact on the safety of vehicles. (1) hardware security design through any lifting key, foot brake, clutch Tata in three ways a reliable lift cruise, in line with the driver used to operate without any additional motion. Normal operation requires less than 1A of the current. (2) the following system of software safety design can not be activated or automatically released. Brake lamp exception safety protection: automatic detection system, if the two sides are found on both sides of the brake lamp failure. No signal protection: when no pulse input signal; signal source abnormal protection: when the abnormal fluctuation is greatly larger or smaller sudden signal; engine abnormal protection: when the engine speed is abnormal fluctuations; abnormal protection: when the vehicle speed or road speed up to 3m per second rate; when the vehicle speed is less than the set 75% of the speed; when the speed is greater than the set speed of 150% high speed setting safety protection: when the speed is less than 40km per hour, more than 180km / h. 4, a cruise is whether the impact on the original structure of the car? No, Cruise control system is independent, does not occur with other preparation vehicle interference. The circuit is connected with a power supply, a power supply, a power supply, a grounding, a speed signal, a brake switch and a clutch switch. The constant speed wire only tightening at the start of cruise, usually in a loose state, do not interfere with throttle activity. 5, why use cruise to fuel? The position and speed of the throttle to keep the best fit, reducing the energy consumption caused by man-made accelerator fluctuations. Different models have the corresponding economic speed, the speed of the most fuel-efficient cruise. Long distance running effect is more obvious.

Diagnostic process of leakage of automotive batteries
Automotive battery leakage is unknowingly to the car off or loss of starting function, many owners have encountered such a problem. Because of its strong fault, so bad judgment is not good diagnosis. Today, small make up the battery leakage diagnostic process to share with you, we want to help.
1, the first inquiry, asked the owner of battery case, if it is in the running process of the vehicle battery is depleted, can first consider the generator or the charging system has a problem.
2, if the vehicle is running all normal, but suspended one day or a few days later, the battery runs out, the first to open the engine cover, check whether there are other battery poles column accidental connection caused by direct short-circuit, check all without ignition switch electric appliances (such as doors, radios, seat heaters, cigarette lighter switch etc.) how often is closing all switches, door and luggage compartment cover.
3, connected to the decoder, switch on the ignition switch, read the fault code, see there is no fault code, if there is, according to the fault code prompt check.
4, if there is no fault code, turn the ignition switch to the off file, remove the battery anode ground wire, in the battery positive lead and battery ground lead series multimeter to Ohm file, in the 1K range in europe. Check the cable resistance, if the resistance is less than 100 ohm, it is the external leakage of the battery; if it is greater than 100 ohm, it is the internal fault of the battery.
5, check the battery external leakage. Disconnect the ignition switch, turn off all electrical appliances, door and back-up cabin, remove the ignition key, disconnect the battery anode ground line, and connecting the DC ammeter between anode and ground negative battery pile head (above the maximum range of 2a), if there is no current meter can also be used to test 5W lights instead of doing simulation test. If the current meter current below 30 ~ 50mA, the lamp test began to shine and then gradually dim, dark red or filament extinguished, is the owner and the leakage caused by careless use.
If the current meter current is greater than 50mA, keep the current meter or try light connection, can use one by one to pull out the fuse wire (in particular, dome, etc.), while observing the change of the current meter or the light and shade of the lamp. If the fuse wire is removed, the leakage phenomenon disappears, that indicates that the fuse wire control circuit has a short circuit problem, and then carefully control the circuit diagram to detect and identify the fault point. There is a very special case: in the case of a single pull out all of the fuse wire, there is still a leakage of the situation, then it should be thought of battery cathode to fuse wire or ignition switch circuit leakage.
6, detection of internal fault battery. First detect whether the battery inside the battery. Normal battery supply voltage should be above 12V, the electrolyte density is 1.26-1.28g / cm, and the height of the liquid level should be in the standard range. The battery discharge tester is used to clamp the positive and negative electrodes of the tester, the positive and negative electrodes are clamped, the test button is pressed, the 12V voltage is continuously discharged after 3-5s, and the voltage indication of the test instrument is observed. If the meter indicates the voltage above 9.6V, indicates that the battery in good condition, but the lack of electricity; if the stability in 10.6-11.6v, indicates that the battery capacity is sufficient; if the voltage is below 9.6V but a value does not move, that the battery is strict

Introduction to automobile diagnosis
An overview of diagnosis
At present, the vehicle factory and the supplier use the on-line diagnosis and the off-line diagnosis diagnosis method.
Online diagnosis: it can run in a car in the process of continuous monitoring of the various components of the electronic control system, such as abnormal, determine the specific fault according to specific algorithm, and in the form of code stored, and start the corresponding fault module function, make the faulty vehicles can be driven to the repair shop for maintenance, maintenance personnel can use car fault self diagnosis function out of trouble codes, fast locate and repair the fault. Therefore, from the perspective of security and maintenance, automotive electronic control system should be equipped with fault self diagnosis function. Since 1979, the General Motors Corporation took the lead in the automotive electronic control system with fault self diagnosis function, the world’s major automobile manufacturers have to follow, in their production of the electric car is equipped with a fault self diagnosis function. Fault self diagnosis function, has become a new car factory and maintenance plant is an indispensable and important means of fault detection.
Offline diagnosis: through the external diagnostic equipment to read the corresponding diagnostic information, to achieve the diagnosis operation. The key to realize off-line diagnosis is how to realize the communication mechanism and diagnostic service between the diagnostic equipment and ECU.
At present, the diagnostic protocol standards are mainly divided into two kinds of systems, ISO (Standards Organization International) and SAE (of Automotive Engineers Society). The United States uses the SAE standard system, most countries outside the United States (including China) using the ISO standard system.
In the field of passenger cars, OEM is from a custom diagnostic protocol, and gradually shifted to the ISO standard. In the field of commercial vehicles, OEM continue to use the SAE diagnosis, the European OEM on this basis to increase the ISO diagnosis.

car diagnostic tool
In the condition of non disintegration (or only unloading of individual parts), the automobile technical condition is determined, and the inspection of the fault location and the cause is found out. Including the detection and diagnosis of automotive engine, vehicle chassis detection and diagnosis, the detection and diagnosis of automobile body and accessories as well as automobile exhaust pollutants and noise detection, etc..
Parameter determination of automobile fault diagnosis method
When the automobile fault diagnosis is carried out, it is usually used to characterize the technical state of the automobile, the assembly and the mechanism, such as the working process parameters of the automobile and the state parameters of the working process. These parameters have physical quantities (such as vibration, noise, temperature, vacuum, power, cylinder compression pressure, etc.) and chemical quantity (such as exhaust gas composition, lubricating oil impurities, etc.). The changes of these parameters can be related to the technical condition of the automobile, and it has a high degree of reliability, sensitivity and reliability. Evaluation of these parameters for the quantitative diagnosis, must establish the standard parameters, such as for vehicle safety and emissions standards, recommended standard factory manufacturing related technical conditions, and suitable for different regions and conditions of use of local and enterprise standards. [1]
Classification and editing of vehicle fault diagnosis method
There are two basic methods of car fault diagnosis: one is the artificial diagnosis, the other is the diagnostic method of the instrument and equipment. Artificial diagnosis is mainly based on the diagnosis of personnel of experience and knowledge, using simple tools, with the eyes, ears, Shoumo sensory means, edge inspection, edge test, edge analysis, and then make a judgment on the technical condition of vehicle. This method is simple and intuitive, and it is also the foundation of establishing the knowledge base of modern fault diagnosis expert system. Instrument and equipment diagnosis method is to use general or special equipment to detect automobile, assembly and mechanism, to provide quantitative basis for analyzing automobile technology condition and judging fault. Some computer control or configuration of fault diagnosis expert system can automatically complete the test, analysis, judgment and decision making. Objective, quantitative and rapid detection rate of the instrument and equipment, and promote the development and application of the vehicle diagnosis technology. In diagnostic practice, two methods are often used in combination, the first is asked to fault diagnosis of the driver, the vehicle visual experience view, preliminary judgment of fault diagnosis using equipment, and further screening and identification, the final confirmation of the fault. [2]
Significance of automobile fault diagnosis
Don’t get the disintegration of automobile technology condition and fault information, for a normal car, is conducive to maintaining the normal technology state, reduce the inspection workload and collapse of the inspection on auto damage; fault for cars, more conducive to the diagnosis and identification of abnormal, for troubleshooting and countermeasures according to the diagnostic results can also be predicting and forecasting the future condition of vehicle.
Development trend of vehicle detection and diagnosis technology
The development trend of vehicle detection and diagnosis technology is:
The use of on-board computer, the vehicle fault diagnosis technology of continuous development and improvement, from the fault self diagnosis of electronic controlled engine gradually extended to include driving, braking, steering system, whole vehicle fault diagnosis;
Due to the application of sensor technology, control technology, fault analysis and recognition technology, artificial intelligence technology and equipment to the development of multi functions, automation, intelligent vehicle diagnostic equipment to diagnose the car, in addition to monitoring and fault diagnosis, fault processing instead of human experts, predict the development direction of vehicle technical condition is inevitable.

With the wide application of electronic control technology in automobile, the modern automobile has become a more complicated control system of machine, electricity and liquid. Because of various kinds of sensors and actuators, the circuit is very complicated, so the fault diagnosis and maintenance of automotive electronic control system has been put forward higher requirements. In addition to the completion of electronic control system for centralized control of the engine (ECCS), automatic transmission control (EAT), anti lock braking control (ABS) and other functions, also has a fault self diagnosis function. It greatly simplifies the process of diagnosis, tedious targeted, the fault diagnosis and maintenance of electric control system become convenient, provides a key for modern automobile maintenance. In the normal operation of the electronic control engine, the fault self diagnosis system monitors all the parts of the electronic control system and the work of the ECU itself, each sensor input ECU signal and the ECU output control signal level are in the range of regulation. Once the input and output signals of ECU, are beyond the scope of the signal, self diagnosis system is determined the road signal failure, at this time, immediately failure lights on the dashboard, and the fault will occur in the form of code stored in the memory of the ECU. Fault diagnosis, according to the provisions of the operation method, you can call out the fault code, according to the fault code table to detect the fault location, fault code for the fault diagnosis has brought great convenience.
The car is the car fault code after the failure of the automobile computer ECU analysis reflects the fault code, general fault code is often caused by the fault sensor, but some fault ECU is read out! There will be some basic fault display on the car dashboard, but it was just a very small the main, or need to read the decoder using apparatus, decoding apparatus has many kinds, such as X – 431, KT300, but the fault principle and read out are the same.
Another point is that the fault code is divided into real code, historical code and occasional code, real code good detection, history is its literal meaning is not cleared before the failure of the fault code, but the occasional fault code is not fixed
The relay relay is located in the box, the car is generally two a is in the cabin, the other one is at the top of the main driving the driver side of the pedal, the first fault code means that the main relay does not work, the power supply part of the fault. The second meaning is that the work of the computer relay does not work, the power supply is not for the past. Third Zheng mean fault engine temperature sensor, fourth means the active switch malfunction. If these four faults occur at the same time, you should find the power supply often do not have the open circuit or open circuit. It’s not the fault code. Because the maintenance of the car needs a lot of considerations. They can’t have problems at the same time.

Car ECU, electronic control unit, also known as “driving computer”, “car” and so on. From the use of speaking, it is a special computer controller for automobile. It is the same as the ordinary computer, by the microprocessor (CPU), memory (ROM, RAM), input / output interface (I/O), analog digital converter (A/D) and plastic, drive and other large scale integrated circuit. With a simple words to describe is that ECU is the car’s brain”.
ECU is widely used in all kinds of electronic control systems, such as electronic control common rail system, ECS system, electronic governor, electronic control distribution pump, electric control pump nozzle and so on.
ECU in accordance with the pre designed program to calculate the various sensor information after processing, and the parameters in the limit voltage level allowed, then sent to the relevant executive mechanism, executive control function of various predetermined. According to the input data and the data stored in MAP, the microprocessor calculates the injection time, the quantity of injection, the injection rate and the injection rate,
Time and so on. These parameters are converted to the time variation of power consumption with the engine running. Because the engine work is rapidly changing, and requires high calculation precision, fast processing speed, therefore, the performance of ECU should be with the development of engine technology and the development of the microprocessor memory is more and more big, the ability of information processing is more and more strong. With the engine speed and load as the basis, through the ECU processing and instructions to the injector and pump sending action, make each cylinder has the most appropriate fuel injection quantity, injection rate and injection timing, ensure each cylinder for optimum combustion. Control of fuel injection and fuel supply for the vehicle now ECU is the most basic function, cruise control, now the exhaust brake control, fuel preheating control, heating control, exhaust postprocessing equipment control, EGR and pressure control and so on, and by bus technology (such as CAN), AT, and dashboard EBS, data exchange and control, it is powerful. Look forward to our country in this regard the level of improvement, the real core technology to achieve the master.
