How to use a scanner for car diagnostics: main functions and features
New car models are increasingly equipped with various electronic sensors and systems. That is why the use of an autoscanner for diagnostic purposes is becoming increasingly relevant. Its functionality is growing every year, but there are a number of basic options that are in demand by almost every car owner. It is them that we will consider.
The main features of the scanner
Let's start with the fact that there are many scanner models. You can get acquainted with their differences and technical characteristics on the specialized website cartools .com.ua. For example, we will consider the capabilities of a dealer scanner, since it has the widest functionality.
The most requested function is reading and deleting errors. They appear in the memory of the electronic control unit as a result of self-diagnosis. This option is currently provided for almost every component of the electronic system. During the operation of the car, the sensor equipment constantly exchanges information with the computer, so the autoscanner can quickly fix a malfunction or error that has arisen.
As for other auto mechanisms, for example, actuators, an open circuit or a short circuit in it is mainly recorded here . For the purpose of additional diagnostic capabilities, there is an option to activate these mechanisms. For the convenience of reading errors, many models of autoscanners are equipped with the Freeze Frame function. By and large, this is a freeze frame of the main system characteristics at the time the error occurred.
The second main possibility is reading parameters. Thanks to it, on the display of the device you can see the main parameters of the car. At the same time, for the convenience of specialists and ordinary specialists, information can be presented in various forms:
- graphic;
- digital;
- according to certain selected features.
Continuing the topic of activation, we can say that it is used not only for diagnostics, but also for checking newly installed mechanisms. Some varieties of autoscanners support the display of technical specifications that are affected by the activation of a new component. For example, when the throttle actuator is activated, the device provides information about the angle of its opening and the speed of the crankshaft.
Additional functionality
After serious repair interventions, elements often need to be adapted. And for some of them, you will need to set the initial operating parameters. These mainly include three components.
- Steering position sensor.
- Throttle assembly (electronic type).
- Fuel level sensor.
Encoding and initialization can also be done with advanced scanner models. In this case, encoding can be performed in relation not only to the computer itself, but also to a separate element that is under its control. Additionally, coding is used to customize some parameters (lighting, door control, trunk opening).
Programming is an important option. It is mainly used when replacing the electronic control unit. Despite the fact that almost all manufacturers of the ECU is a universal component, there may be differences in some safety and environmental requirements. It is on the basis of this that the appropriate software is loaded into the block.
If we talk about ease of use, then almost every modern auto diagnostic scanner has such an important option as wireless data transmission. It is implemented using Bluetooth, Wi-Fi and GSM technologies. This allows you to significantly simplify synchronization with third-party devices and equipment.
The scanner can be used without direct contact with the car. This is realized thanks to the remote diagnostics function. In particular, it is available in EasyDiag devices. The possibilities for processing information here are very wide. You can print reports using the integrated printer, several wired interfaces are supported at once, separate software modules are selectively installed.
