What Automotive Scan Instrument Really should I Get?

Professional Scanning Equipment - obd2 code scanner: Snap On
Snap On Resources features several specialty automobile scanners which plug into a car's OBDII port. The benefit of utilizing expert grade scanning resources such as people supplied by Snap On is the fact that they get the job done with multiple vehicles and can scan the whole car or truck for troubles. Specialist Snap On scanning resources incorporate extra adapters for use with automobiles manufactured following 1980 as well as upgrade capability. Snap On diagnostic scanning tools is often up to date every single yr to contain new automobiles produced within the recent model 12 months. The best downside to professional scanning resources is definitely the value; Snap On diagnostic resources price in extra of $1,000 (as of 2011), generally producing them a feasible concept only for specialists.
Professional Scanning Equipment: Matco
Professional diagnostic scanning tools from Matco are priced in regards to the identical as Snap On tools, and present the identical level of diagnostics. Matco scan resources also plug to the OBDII port of your vehicle for being checked. Matco scanning tools can be updated just about every 12 months to cover new automobiles -- in the similar way that Snap On tools can -- as well.
Amateur Automotive Scanning Tools at http://www.autelsale.com
Amateur automotive scanning resources are available from a selection of corporations. While these scanners do not have the capabilities in the much more costly professional scanners, they do bear a a lot reduced price. Count on to spend concerning $200-400 for a quality diagnostic scanning device from companies this kind of as Equus, Actron or AutoXray. These units are comparable in lots of respects in that each of the units plug in to the OBDII port on your auto and deliver readings for many on the computer's functions; they differ mainly in the packaging from the diagnostic resources. All three enable you to clear trouble codes and also scan a vehicle's computer.
Scanning Equipment to Avoid
Scanning tools, by their pretty nature, are highly-priced to purchase and very own. For that reason, it's important to be conscious not only that there are actually new scan tools of dubious high quality about the industry, but also secondhand scanning tools that ought to be avoided. Any automotive scan tool priced under $100 ought to be suspect. Even between applied resources, costs beneath that stage tend to indicate that there is some dilemma using the unit. When skilled scan resources might occasionally be supplied for sale in secondhand retailers this kind of as pawn shops for very low charges, a professional scan instrument supplied to get a value that is certainly as well fantastic to get correct may be stolen.

The automotive airbag constructed using conservation

Car obd2 android airbags, has become an important indicator to determine the safety of a car. But this matter of life and death the airbags but few people know how to maintain it, and said air bag construction, performance ...... more little known.
The airbag of the present invention
The prototype of today's automotive airbag actually invented by Americans Jhon W Hetrick a cushion. As early as 1952, he invented a device which he called a "safety cushion".
But this cushion is just a pure mechanical factors due to the protective effect is not obvious, high manufacturing costs, as well as the expansion of the gas fast enough, and therefore did not cause widespread concern for car manufacturers. But as the sixties and seventies of the last century automobile manufacturing technology leap, speed faster and faster, traffic accidents will become a headache by-products, at a time when the topic of the airbag was re-instituted.
The structure car code reader and principles of the airbag
The airbag abbreviation SRS, generally by collision sensors, computer processors, gas generator and the main airbag several parts. Used to protect the driver of the main airbag is housed in the steering wheel, while the rest of the airbag due to the type of the protected position were installed in each corner of the car, some luxury cars are equipped with up to more than 20 Airbag, but need Note that, the car safety is determined by many respects, much of the airbag is not the sole criterion for a car OBD2 Code Scanner safety factor.
When the vehicle collision, the collision sensor and computer will determine the intensity of impact, and promptly issued a directive to the air bag. However, the impact of the airbag deployment to protect the safety of occupants at the same time, may also be dangerous hazard, not the airbag opens necessarily safe. And the faster the speed, the time of the collision, the shorter the short-term, once the collision time than the airbag outbreak time, the role of the airbag is very small.
The use car diagnostic tool and maintenance of the airbag
Under normal circumstances, the airbag from the factory until the end-of-life are not self-maintenance. Each time you start the vehicle, the dashboard SRS warning lamp lights for about 5 seconds in the self-test, the warning light automatically turns off when the computer is confirmation. If the warning light has been flashing, it indicates that the airbag system is faulty and should be serviced immediately.
In addition, the air MB star bag in the pop-up instantly with great force, so do not be placed near or in front of the airbag any article. And the airbag is a one-time use items need to be reinstalled after the pop, the cost is not Fei Fujia bit no one, can be considered close airbags.

Fall car maintenance if you ignore them

Transferred to autumn, the obd2 android air becomes cool, hearty mood carrying the whole family to travel by car, enjoying the modern equipment to bring you the fun. But only to take good care of your car, it will not disturb your taste.
You will give your car a lot of maintenance, inspection body paint and chassis, car tires and maintenance to the car for antifreeze, automotive air conditioning maintenance, car sterilization cleaning. These conservation is essential, very important, you may not be ignored. However, you will notice that homes the car system maintenance, heaters pipeline and fan maintenance, air inlet or air intake grille, electronic fan and maintenance, and so on? They are also very important, but often the owners have ignored!
First, the maintenance of the car code reader engine compartment.
Into the fall, you should always check the engine compartment of the oil, brake fluid and antifreeze, and see if the oil is sufficient, whether the deterioration of whether the replacement cycle, the oil is like the blood of the car, to the replacement cycle, be sure to replace , in order to ensure the patency of the fluid circulation
Secondly, the brake car diagnostic tool system maintenance.
Always check the brake any weaker, deviation, whether there are changes in the brake pedal pedaling efforts, if necessary, clean up the entire brake system pipe section
Once again, the warm air pipelines and fan maintenance.
Autumn weather turns cold, the temperature is low appears white frost, in this season, you have to pay special attention to the windshield defrost vent out of the wind is normal, heat enough, if there is a problem to solve, otherwise, they will to bring your driver's insecurity.
Also, the OBD2 Code Scanner air inlet or air intake grille, maintenance of the electronic fan.
Should always check whether there is debris in these areas, if there is debris, you can use compressed air to blow away the dust, In addition, the engine cooling state, using water from the inside out flushing or more parts.
In addition, the door shaft, rail due to the invasion of sand and car wash is easy to rust, open, will be issued when abnormal sound off, such a problem as long as regular coated with anti-rust oil in the above can be solved.
Car paint, tires, air conditioning, sterilization conservation is important, but do not forget the details of car MB star maintenance.

Pay attention to what your car's maintenance

Into the late autumn, the obd2 android weather is getting cool temperatures followed getting lower and lower, people have to wear a warm coat to prevent the invasion of cold air, at this time, plus their own to wear jackets, and do not forget your love car, while in the late autumn season for it to be a maintenance, take it away from the cold air hazards, you drive up warm and pleasant.
Antifreeze Note replacement
Hubei hair technology car code reader officer on behalf of the master said: "After cooling, the owner should be timely to 4S shop to check the engine cooling system, pay attention to antifreeze whether to replace, because many car owners love to use tap water instead of antifreeze in the summer, and the temperature declines, tap water is not as good as the antifreeze so easy to use, cooling and circulation mobility may not meet the requirements, so pay attention to replace. "
Antifreeze performance is reflected in the following aspects: First, the corrosion of metal parts in the antifreeze prevents automotive engine cooling system, it will protect these parts. Secondly, the lower the freezing point of antifreeze, generally in the minus 20 ℃, significantly below the freezing point of the tap water, lower temperature because icing will not affect the normal operation of the cooling system.
In general antifreeze car diagnostic tool is replaced every 100,000 kilometers, within a year, you want to check whether the freezing point of the antifreeze to avoid the occurrence of such a failure within the standard range.
Of particular note is the purchase antifreeze must choose the brand of your car engine, the firm can not use fake and shoddy antifreeze mixed with each other and different brands of antifreeze.
Oil Note to be replaced
Oil has been dubbed the "blood" of the engine, signifying its importance. Wide of the friendship store service manager Bear Gang told reporters oil into ordinary oil and two Universal Oil, Universal Oil in cold winter, but also in the hot summer months to use, do not distinguish between.
The ordinary engine oil is necessary to sub-winter oil and summer oil the the winter summer oil, oil will become very sticky in the cold, start there will be a lot of resistance, resulting in difficult to activate, start the engine speed reduced. Vehicle owners in the autumn and winter should make the car sump and air compressor internal oil engine oil replaced by winter, to guarantee lubricating quality, and secondly, can also play a protective effect on the engine.
So how we will choose the oil? First of all, oil is not the more expensive the better car engine oil plus the brand owners should be strictly in accordance with the requirements on their own models of the car user manual; Second, oil viscosity graded "W", 0W, 5W, 10W , numbers lower, more dilute the oil, the more suitable for autumn and winter use. Xiongjing Li said: "In the winter 5W like Wuhan is more appropriate."
Tire attention OBD2 Code Scanner to a good tune Pressure
Owners experienced when the summer driving will tire pressure let go a little, to prevent the temperature high risk of puncture. To fall cooling, it is necessary to supplement the tire pressure to the tires, and maintained at the prescribed air pressure within.
Autumn rain frost weather multiplied slippery road surfaces also require the tire to be able to maintain a sufficient degree of friction, if the tire surface is badly worn, must be promptly replaced new tires, repeatedly patched tire also try to replace. Cold weather rubber tires hard and brittle, reducing the coefficient of friction, easy to leak, bar tires, even replace the new tires, but also often in the tread of the tire surface debris clean up, check for scratches, drum kit.
Another warm cushion
The cushion is most closely in contact with the owners, in the Autumn, the first should be replaced is the car seat cushion. Currently, many different types of cushions on the market, including velvet pad and so on. Economy cars can use an ordinary velvet pad, cartoon cloth, wool-like mats affordable; in the premium sedan can choose pure wool pad, Australian wool pad.
Experts advise MB star owners, optional cushion must be carefully feel, touch, smell with the nose, with or without odor and hair loss phenomenon. Use, but also to attract attention, especially smoking owners, try not to smoke in the car, because the autumn air dry, and this type of woolen goods easily catch fire.

Keep a car in winter Ten concerned about the main points

It was winter, the obd2 android owners do not forget to maintenance of the car in order to be found during maintenance and troubleshooting.
1, body
Paint coating or sealing glaze for the car to be the best in the winter, are able to resist the erosion of acid rain snow. In addition, after the snow road sprinkling salt water, salt water splash to the body of the vehicle with great harm to the paint, advance somewhat preparedness, snow travel is not afraid to damage the paint.
2 Chassis
Winter, car chassis car code reader always directly deal and rain, snow, and very easy to rust. Snow over the fine weather, the chassis of the car began to rust. So, in the rain and snow before the advent of you may want to take a moment, to the chassis to be a the antirust care.
3, battery
Battery is most afraid of low temperature, is much lower the electrical capacity battery capacitance than room temperature in the low temperature environment. Therefore, before the advent of the cold season, should supplement the battery electrolyte, at the same time clean the battery terminals and coated with a special oil to protect and ensure a reliable start to extend battery life. If the vehicle is parked in the open air or cold storage for several weeks without, the battery should be removed and stored in a warmer room, to prevent damage to the battery icing.
4 tires
Tire rubber will car diagnostic tool harden in the winter and relatively brittle, friction coefficient will reduce the tire pressure is not too high, but more can not be too low. Low external temperatures, the tire pressure is too low, the soft tires serious accelerate aging. In addition, the tire wear very different inside and outside, in order to ensure safety to reduce wear and tear, should periodically replace the tire position.
5, the light
The winter fog blooming, low visibility, they must be timely observation of fog lights, high level brake light is working properly, found that black light bulbs must be replaced as soon as possible. The ordinary halogen headlamps general use of the light will be reduced after two years, the best time to replace or repair.
6, the cooling system
Regularly check the MB star water tanks, pumps and belts, pipes and other parts are working properly. Some cars summer water temperature is high, the repair personnel put the thermostat removal, can solve the problem in summer, but winter on the reverse. If you do not pay attention, it is possible for a small pipe, a waste of a bucket of antifreeze.
7, heaters
The car's heater system did not use for a long time, it is inevitable there will be a lot of glitches. Such as hot air fan running abnormal sound duct blockage, although not affect traffic, but maintenance is very troublesome. So, be sure to remember to take advantage of the opportunity of routine maintenance, repair station to conduct a comprehensive inspection of the car's heater system, the problems to solve.
8, antifreeze
Antifreeze seemingly trivial, but the car is great, ranging from clogged pipe, heavy corrosion damage to the cylinder, so be sure to check whether the lack of fluid, whether the deterioration replenish or replace. In general, the antifreeze should be changed every two years.
9, the engine
Owners often find OBD2 Code Scanner winter car engine as if the person is depressed, the work is not hard. Because of low winter temperatures, resulting in antifreeze, motor oil and other effects have diminished, the engine is less than ideal working environment. Antifreeze, motor oil, gear oil, in accordance with the provisions of the time or mileage replacement, must not improvise. Dirty driving environment, the best time to change the oil in the winter than the time specified in the instructions on the advance. In addition, winter is the best choice for manufacturers stipulate grade gasoline in the fuel, so that the power will be better, such as the usual 90 gasoline, winter can be exchanged for 93 gasoline.
10, a windscreen
Winter wiper should regularly scrub, snow ensure that scrape the windshield. Out at dawn wiper to the snow stick in the windshield, do not use hot water to rinse directly so easy to make the windows burst because of temperature changes, wiper deformation. The correct method is air conditioning to the hot air hair mode for the front windshield until the wiper naturalized open. In addition, the glass of water should also replace antifreeze.

The car thread locking measures

Car thread obd2 android Vice securely connected or not directly affect the use of the car and this locking measures in the design of the car, friction locking spring pad locking, the preload locking or specially since locking threads, etc.; mechanical locking with locking cotter pin, locking plate locking fuse locking.

1, spring washer should be good elasticity, suitable size
Spring washers are easy to install, low manufacturing cost, and is widely used in the automobile. It is the use of the elastic deformation of the gasket, so that the axial direction of the screw vice tensioning gasket beveled tip also contribute to the anti-loosening. However, car code reader this washer during use due to heat or long compression lose their elasticity. Therefore, before installing spring washer, you should check whether the failure of its flexibility. Check is to look at the two ends of the gasket at the interface whether or shifted up and down a certain angle, this washer hexyl VALID if the stagger angle is small or not staggered. Washer size should correspond with matching bolt size washer outside diameter slightly kid nut outer diameter appropriate.

2 cotter pin length should be appropriate and engine connecting rod connecting bolts loose, cause connecting rod bearings Songkuang, the engine produces abnormal noise, or even damage to the engine-related parts. Decomposition abnormal sound check some of the connecting rod bearing failure, often found individual locking nut on the bolt connecting rod cotter pin has gone, the reason is mostly due to the cotter pin is car diagnostic tool too long, high-speed movement of the crank arm scraping hit break, finally shedding. The method of determining this cotter pin of the correct length is a cotter pin inserted through the corresponding hole of the lock nut, the percussion hammer in place by hand, the cotter pin projecting does not exceed the length of the crank arm plane, and then required the cotter lock i.e. can.

3, Disc spring washer assembly should be directed to
The disc spring gasket on the mechanical surface will not produce more scratches, thus increasing use in the car, but if improperly installed, will not serve to prevent the thread loose collaboration with. For example the second axis of the: Dongfeng EQ1090 car transmission rear flange locking spring gasket installed between the nut and OBD2 Code Scanner the flange dish dread, if improperly installed resulting in the nut loose, cause the speedometer drive gear slipping the odometer speed indication and Mileage errors. Meanwhile, around the second shaft traverse so as third gear skip shift occurs. The correct orientation should be of the belleville spring washer concave surface facing the connecting member, the convex surface facing the nut. Thus tighten the nut, since the belleville spring washer is deformed by force, the support surface by reaction force play lockup role.

4, the insurance should be correct wire taut direction
Some parts of the chassis of the vehicle (eg, shift forks and shift fork shaft connecting bolts) insurance wire to prevent screw loosening, it is commonly used in the threaded locking bolt group. The insurance wire locking more reliable insurance wire size selection and penetration of the screw holes taut direction, but the installation should pay attention. Insurance wire is too rough is not easy to go through, the diameter should be slightly smaller than the diameter of the perforations, when a slight resistance can be interspersed. Wire penetrate right direction of the difference between insurance: the to a bolt Loosen insurance wire in a taut state, that unscrew the two screws tighten a bolt will be its adjacent right otherwise incorrect.

5, the locking MB star plate should be locked in the side plane of the nut
Larger pieces on the car nut locking constant locking of the locking plate, such as automotive steering knuckle lock nut transmission the second axis of the front locking nut. Locking tabs lock nut torque required to tighten the locking tabs off to the one side of the plane of the nut with a hammer to fit snugly against. Locking plate must not be attached to the edges and corners of the nut, so that is not good to play the role of the locking.

The car modification Mistakes knew

Today, many of obd2 android my friends in the car owners love their cars "beauty" or "face" to carry out some simple car modification was to the comfortable and beautiful people in order to enhance the dynamic performance.
The face of the numerous conversion projects, experts recommend choosing modification projects for their actual needs and body condition.
Myth One: The converted audio "the more the better."

Some of my friends car code reader think that when the modified car stereo multi-install wireless remote control, multi disc converter auxiliary facilities can enhance the actual effect of the car stereo. In fact, the host of the sound is the soundtrack of the entire sound system, to determine the sound quality of the core. Speakers, crossover expanding device (AMP), overweight speakers (Sub Juan woofer) also have a significant impact on the overall effect of the audio, if ignored any more, even if the number of installations of more complex functions ancillary facilities for practical effects in terms of improving sound to no avail. Therefore, instead of doing some modification, it is better to costly and laborious practical to choose a good host.
Myth: soundproof thoroughly
Some car owners do cars do sound excessive pursuit of sound insulation, sound insulation requirements will be extreme, even hope can not hear the sound of the engine.
We can imagine, if the driver car diagnostic tool can not hear the sound from the road and power systems, will lose access to the relevant information on road conditions and vehicle condition and judgment, to affect traffic safety. The ultimate purpose of the modified car noise, not to eliminate all sound, but to eliminate the noise. Therefore, do not the car interior space transformed into an out-and-out "Silent World" penny wise and pound foolish.
Myth: blind installation of the tail
Retrofit tail now also become a fashion, but not all models are suitable for mounting tail, because the tail of the role is to increase the stability of the body, the more crucial for large displacement of the car, but for small-displacement models Install the tail will have a certain impact on the speed. In addition, the rear wing is a spoiler components, simple installation of the tail in order to achieve exaggerated or aesthetic effect, it will play some negative role. Because the role of the tail is to raise under pressure in the case of high-speed vehicle dynamic balance of features and body, but after careful adjustment to achieve the desired effect. Blind installation of the tail can be counterproductive in the car at high speed, such as cause car unidirectional balance problems affect car safety.
Myth: loaded "surrounded by" OBD2 Code Scanner demolition bumper
Some of our friends to make the vehicle more elegant shape, installed for the car surrounded by large. Retrofitting "surrounded" does make the vehicle lines look more smooth, but some friends over "beauty", the installation is not surrounded by large components installed in the original car's bumper, and select demolition out of the original car bumper, then install.
So if the car is beautiful, but the people in the car also will become unsafe. Remove the original car bumper, means that if the car in case of a collision, the lack of bumper protection, and the cars are likely to suffer more serious injuries.
Myth: installation of large-diameter exhaust pipe car will run faster.
The pursuit of speed is the dream of many of my friends, some owners believe that the installation of large diameter exhaust pipe can let the car has more power, also appears on the sound style.
An auto repair MB star experts said, simply replace the exhaust pipe for the power upgrade with little effect. Under the premise of the engine does not do the conversion, only to replace the exhaust pipe, and can not play the role of power improved significantly, and this is even harder for small displacement naturally aspirated car. From the actual operation, the most obvious effect is simply modified the exhaust pipe of large diameter to form a sound momentum, but it will cause noise pollution.

Automotive transmission disassembly points

Automobile transmission disassembly precautions:

1, first remove car diagnostic tool the gimbal screws, transmission and drive shaft universal joint separation; then remove the clutch cover screws, so that the transmission and clutch; remote manipulation of the transmission, the control mechanism is the transmission body separation last removed the transmission from the car.

2, sludge and dirt, cleaning transmission outside attention to the protection around the head of the shaft. Latest the car cushion rankings released 10 strong

3, unscrew the MB star the decentralized oil drain plug, put the net transmission lubricants, and then screw the oil drain plug.

4, looking for a clean and dust-free venues removal tool and Copper Rod, began to disassemble the transmission. The disassembly sequence is generally: the transmission cover, the first shaft, the second shaft, an intermediate shaft, the reverse gear shaft.

5, demolished parts, optimistic about the parts of the original direction and position after the demolition, if necessary, make a record; the removed parts disassembly sequencing, sub-site emissions neat, if necessary, available line or wire parts order strung together; gear sets of the original orientation and position on the shaft, to prevent loading the wrong or missing equipment.

Disassembly of car code reader all parts should be clean, and do the appropriate checks, can not continue to use should be replaced; demolition of oil seals, gaskets generally should not continue to use and should be replaced.

7, before assembling various bearings, oil seals, shaft keyway, the bore of the gear and transmission case bearing bore with gear oil or engine oil, and to replace the paper pad soaked in oil. Taobao car cushion

8, the assembly sequence disassembly sequence the contrary, that after the removed parts first load, so that all parts are installed to the original position, the installation process often turn the mating parts, pay attention to the direction of oil seal and shall not be damaged.

9, install obd2 android transmission cover, should check the site filled with a seamless parts, the shaft and fixed gear axial movement throughout the pad of paper is intact, whether the gear engagement within all tooth width; using hand struck the sliding gear, to see whether the axial movement of the engagement to the whole tooth width; hand rotation of the first axis, respectively try each block should be flexibility to smooth rotation, no jam phenomenon. Adding the right amount of oil in the gearbox body in accordance with the regulations.

10, the fork mount and secured to the corresponding fork shaft, and then loaded transmission cover the corresponding holes in the fork shaft. Installing fork shaft to pay attention to the self-locking mechanism and interlock mechanism to be loaded into the corresponding holes in the fork shaft side of the three grooves response to the direction of the positive self-locking mechanism Ball fork shaft has a groove side of positive interlock mechanism. Each fork shaft are installed in place after it was placed in the neutral position, the slide gear in the shift power transmission mechanism is also placed in the neutral position, the transmission cap is mounted to the transmission casing, each fork precisely mounted to the corresponding gear dial tank fitted with connecting bolts, in accordance with the provisions of the order and the provisions of the torque tighten the bolts, hanging with the shift lever into different block, followed by checking the success Guadang not linked on gently back and forth rotation The first axis, still hanging on Remove the cover check.

11 installed, OBD2 Code Scanner to make a trial run, each block should be flexible rotation, no oil leakage, oil spills and jam phenomenon, is not allowed in any gear gear jump, the phenomenon of chaos gear shift should be lightweight and comfortable not abnormal noise and overheating....
