Buyer’s Guide: Make an Informed Choice
Scanners are supposed to make your mechanical tasks of vehicle testing and repair easier. The problem is that not all scanners can do the same. All of them promise the same specs and try to lure you with almost similar prices. So, simply the features cannot be your answer to buying the perfect tool. Look into other aspects to find the one that gives the best performance.
Ask and answer
OBD I was stopped after 1996. OBD II took its place. But there are still cars that may have the OBD I model. Most scan tools will not provide you the necessary plugs to scan them. Look for a scan tool that can also comply with the older models and give you the widest range of vehicles.
Your vehicle scan tool can provide you with the generic scanning capabilities. Or, it can go beyond that to provide you with additional benefits. Choose wisely.
All manufacturers have made vehicles such that now all vehicles comply with OBD II norms. All your scanners will be able to function with them and retrieve data from the ECU. To go a step ahead, and command things beyond the ECU, your scanner needs to have access to the particular Manufacturer Specific Codes. So, when you decide to buy a scanner, look for one that complies with the particular manufacturer that you want.
Are you in the automobile industry or work in car repair and maintenance? You will need to have a report of the faults in the vehicle along with the tests and corrections that you did on it. While some scanners do not have such a developed interface, a few do. Invest in such a scan tool that allows you to show proof of your work. It is useful for your client as well as while claiming an insurance.
The best part about a bidirectional scan tool is its ability to illuminate the state of your vehicle without you having to take it apart. The icing on the cake can be a scanner which provides you with Live Data Values. The technique is used to convey the values of every component of your vehicle in real time.
The scanner scans the engine rpm, fuel pressure, coolant temperature sensor, and air injection. These are crucial to the health of your vehicles. They are also important for future reference and comparison. Learn to interpret OBD II values on.
Remember, every vehicle may, at some point of time, require you to use spare parts. With 69 million vehicle breakdowns occurring in the US every year, spare parts are even bigger necessity.
Most such parts, nowadays, are coded so that these codes can be used to calibrate them with the ECU. Spare keys, radios etc. are all coded these days. This bidirectional communication is what is useful in entering the codes. If your scanner does not have this facility, it will be of no use to you in future.
You may have made your decision by now, after going through our reviews. Tell us which one you chose and why. We believe the LAUNCH X431 Pro Mini is the clear winner. The considerations while buying a bidirectional scan tool include compatibility, reset engine light ability, response time, ABS/SRS system, and help database.
All these needs are met by the LAUNCH X431 Pro Mini Scanner. It is compatible with both the OBD I and OBD II systems. Plus, it has good response times and has 20 reset services including check engine light. The bidirectional communication capability allows it to configure the ABS/SRS system. If you ever encounter a problem, the lifetime tech support and its multilingual interface helps. It’s why this one is among the best bidirectional scan tools in the market.
The LAUNCH X431V+ is quite handy but lacks as much compatibility. The LAUNCH X431 V+ (Upgrade from X431 V Pro) falls short when it comes to providing a help database. This can be a major issue for many consumers.
The LAUNCH X431 V Pro is perfect except it has parts whose working is difficult to decipher. This makes the scanner difficult to understand completely. The LAUNCH X431 DIAGUN IV loses this race because of its difficult ECU coding. There are no clear guidelines available. This makes the entire function useless. The LAUNCH X431 V+ (Upgrade to X431 V Pro) is also perfect except for its inability to work with OBD I models. This makes it a less popular choice in the market.
