The Car Computer Failure Problems

Posted on by blogger

Cars damaged when the computer can pull to repair the computer, the following test tool used to launch x431, lexia3, mb star. Here are some computer malfunction:

The first is part of the computer power supply failure. Generally because the vehicle charging, the charger voltage regulation due to too high, or reversed polarity or charge while opening key, or even start the motor, or engine during operation, causing the battery connector loose generator directly to your computer board power supply and other reasons. This will generally burn high-power components such as voltage regulator diode, change can be relatively easy to repair.

The second is the input / output part of the fault. Amplification circuit element is usually burned, sometimes accompanied by follow-steel lines blown circuit board. For example: a repair shop in Taiwan and USA Chevrolet sedan on a renovation of paint and found that the engine can not start, and if you open the keys over time, gasoline from the exhaust pipe, oil pan, etc. overflow. Open the keys and found that all six fuel injectors are fully open state, gasoline directly from the nozzle into the cylinder, flow over after the overflow, check the external circuit found no problems, it can be concluded that the output of the computer control failure. Detection methods can be used is launch x431. Open the computer case examination revealed nozzle control signals on the amplified high-power transistor has a breakdown short circuit, causing power nozzle that is normally open state. Replacement of a similar type of transistor and clean up after replacing engine oil, the engine can operate normally. To note here: Many EFI vehicles through paint, then start all kinds of faults often occur, because after the car interior through the paint, especially in circuit accumulated heat within the device and heat, and the heat from the inside slowly comes out of the depths, and electrical equipment to work easily in the high temperature failure. Therefore, do not immediately drive the truck out after baking, but should be cooled through the full start, if the production of stress need to free paint room, you can use human power to push the car, let it cool down, the re-start.

A third part is the memory failure. A total of four kinds of memory, read-only memory (ROM) is used to store computer monitoring program that the computer itself, some of the procedures that must be run. Programmable read-only memory (EPROM or EEPROM) is mainly used to store for the implementation of devices or other control devices for the control program. Such as: fuel injection control, ignition advance angle control. Idle speed control and self-diagnostic procedures. Random Access Memory (RAM) for temporary storage of data from various sensors for CPU use; also the fault code storage systems. Random memory contents will disappear after the power failure. Need to know this detection technology lexia3. Adaptive memory (random access memory belonging to a) for the computer’s “self-learning” and in accordance with vehicle speed, automatically adjusts the parameters. Such as “idle learn” and so on. To eliminate the programmable memory (EPROM or EEPROM) problems can be replaced, need to find a well-known memory chip with program content, buy a blank chip with the model, by writer, from the read the original film program, and then to write to a blank chip, new chip can be copied, and then the new chip into the computer. But most car manufacturers are set up to only copy 3-7 times more than the number of after no longer using, and some manufacturers make chips by means of an encryption can not be copied.

Last case is a special failure. Off by the flooding of vehicles, computers plate corrosion occurs, the component pin circuit, adhesion or component damage, can repair or replace components by check. For example: a repair shop received a Cadillac car repair, fault phenomenon: when the normal operation of the engine if the on / off headlights or other electrical equipment, exhaust pipes blasting phenomenon occurs, the exhaust pipe can be serious burst. Better detection technology is mb star. The inspection found that the external circuit is not the problem, suspect faulty computer, open the computer box carefully monitored and found that a ground wire for corrosion circuit, the grounding line is the oxygen sensor signal shielded cable inside the computer grounded through the location, because Duanlu to shielding failure, caused by oxygen sensor signal interference caused by other appliances, with a tin solder through time, that is back to normal.

These are some common computer failures will be encountered in the actual work a variety of fault phenomena, as long as a clear principle, and acquire a certain way, analyze specific issues, finally has a solution.

Car Alarm Industry And Manufacturers

Car alarm is a vital component of car security system. Its growing demand proves it is effective against car theft and burglary.

Car alarm systems range from basic to highly advanced. The manufacturers keep on distributing a wide variety of models. They still manufacture large quantity of one-way car alarms. Two-way car alarm systems are mostly produced for distribution in developed nations.

Many car alarm makers are now manufacturing car tracking system employing the technology of Global Positioning System. Police can now track the movements of stolen vehicles using this system. Prices are more or less stable in spite of the rising cost of materials due to the tight competition among manufacturers.

Many companies producing car alarms acquire highly advanced equipment and introduce computer testing system to meet customers satisfaction. Their products are carefully tested at facilities with simulation testers and temperature chambers to ensure reliability.

Their engineering departments develop high and technically advanced car alarms to satisfy the special requirement and certification of countries worldwide. Manufacturers also offer the most affordable cost effective shipping methods, and they make sure that products are always delivered on time.

Makers of car alarm are looking for ways to mass produce hybrid car alarms attuned to the standards of the National Insurance Crime Bureau for vehicle security.

Hybrid alarms for automobiles are more durable and in many ways better than traditional car alarms. Most manufacturers concentrate on improving the quality, enhancing stability, reducing power consumption and bettering control range of their products. They even distribute accessories like central locking kits and reversing sensors.

China ranks fourth among the worlds largest car manufacturers. Its car production is estimated at 5.1 million in 2004 and the actual sales have reached 5 million units. Because China has a big local market to serve, car security industry has also expanded, serving both the domestic and foreign markets.

Taiwan has moved most of its production of basic car security alarm to the mainland and scaled down on its own manufacturing. Nevertheless, it focused on providing comprehensive car security solutions and satisfies specific requirements.

The increase in demand for car alarms and other car security products in China are considered sustainable. International players continually strengthen their presence in China attracted by the foreseeable growth of car security business and car manufacturing. Both Taiwanese and Chinese manufacturers have penetrated the car security OEM (original equipment manufacturer) market already.

Directed Electronics Inc. is one of the largest companies in the world distributing car security products. It is the company behind Viper car alarms. It is largely praised by installers and customers for its great features and benefits integrated into the system.

JSC Diveti is a company established in 1994 in Kaunas, Lithuania. Few years later, this company became one of the biggest importers of car security systems. The company begun the production of car security system named Sharpshooter in 2004.

The alarm system is manufactured utilizing the technology SMD (surface-mount device). The excellent design process and the creativity of Divetis was evaluated then certified by accredited international laboratory.

Guangzhou Car-mate Technology Co. Ltd; manufactures, researches and exports car electronics products. The company produces GSM car alarm, GPS car navigation and HID (high-intensity discharge) xenon kits.
