Formerly, diagnostic and test tool is jus used by the car repair shop but today, many individual customers also start to choose this tool to solve the problem of their car. There are two main kinds of diagnostic and test tool on the market that is product for industrial customer such the car repair shop and product for individual customer with the certain difference about function as well as price.
If you are in demand to choose a diagnostic and test tool for personal demand but you do not know how to choose a quality tool then in this guide, we will introduce about the best diagnostic and test tool for personal demand.
Code reader can be considered as the most basic type of diagnostic and test tool. Main function of code reader is to access into system of the car and shows the fault codes. Normally, most of code reader just has ability to provide fault codes therein some better products will show code with a definition for user.
Price of code reader is usually cheap – a few dozen dollars however function of it is also limited and it is just a suitable choice for personal demand to help users read and clear fault codes of the car.
Code reader can also be used to turn off check engine light but you need to know that code reader can not be used to scan fault of the car because it is just designed with function to read and clear fault codes. It does not show any information about sensor or other systems of the car if you want to do this then you will need to use scan tool or diagnostic scanning tool.
And you also need to know that core reader just has ability to read fault codes of your car but it does not ability to help you find and determine exact position of this fault.
Through fault codes found by code reader, you just know that there is fault on the car but you can not know what caused it therefore code reader is just used to support to diagnose about fault of the car. In order to find and diagnose fault, you will need to use the other tools that is expensive than code reader many times.
Ability to show fault codes of each code reader is not the same. This thing is depending on function as well as design of each code reader. Most of code readers are designed to read fault codes on OBD II system however some older code readers will be designed with ability to read fault code on OBD I system therefore you need to determine OBD system of your car to choose a suitable code reader.
Scan tool is more modern than code reader. Scan tool also has ability to read and clear fault codes such as code readers but it also has other functions such as ability to show information about sensor and data system of the car, status of OBD II system or the basic operations such as air flow, loop status and so on but it can not implement the complicated jobs.
Price of scan tool is higher than code reader – a few hundred dollars. Although function of scan tool is better than code reader however it also has limit therefore it is just suitable for individual customer to service for personal demand to solve the simple faults of the car and it can not be used to solve the complicated problems of industrial customers.
