Enter “System Selection”, you can also diagnose the vehicle according to the system according to your needs after selecting the model.

DIAGNOSIS FUNCTIONS

Diagnostics functions supported by the scan tool are listed below:

• Read ECU Information
• Read/Clear Trouble Code
• Read Live Data
• Freeze Frame
• Actuation Test (Bi-Directional Control) Special functions

READ ECU INFORMATION

This function is to read ECU version information and is the equivalent of “System Identification” or “System Information in some electronic control systems.  These equivalent terms all refer to reading ECU-related software and hardware versions, models and production date of diesel engines, part numbers, etc. This information is helpful when recording maintenance records and ordering new parts

READ TROUBLE CODE

In the process of diagnosis, if the device shows System is OK or No Trouble Code, it means there is no related trouble code stored in ECU or some troubles are not under the control of ECU. Most troubles are mechanical system troubles or executive circuit troubles. It is also possible that the signal of a sensor may be inaccurate but within limits, which can be examined using Live Data.

CLEAR TROUBLE CODE

It allows for clearing current and historical trouble codes stored in the ECU memory, under the premise that all the troubles have been resolved.

Some troubles are immediately detected by the ECU with the key in the run position and without the engine running. Other troubles are not detected until very specific test conditions are met such as engine coolant temperature within a range, speed within a range for a duration of time, throttle percentage within a range, etc.

• If the trouble codes are erased when the trouble remains unresolved, the trouble code will reappear in the ECU the next time the ECU performs the specific diagnostic test for that trouble.
• If the trouble is resolved but there is a stored trouble code, sometimes the ECU will detect the resolution and clear the
• If the trouble is resolved and the user clears the trouble codes, the trouble history will be cleared.
• If the user intends to have another colleague or mechanic investigate the problem, it is not recommended for the user to clear the trouble code since doing so may erase information helpful to others who may investigate the issue.

READ LIVE DATA

Real-parameter identifications (PIDs) of the running engine such as oil pressure, temperature, engine speed, fuel oil temperature, coolant temperature, intake air temperature, etc. Based on these parameters, we can predict directly where the problem lies, which helps to narrow the scope of maintenance. For some vehicles, during their actual operation, the problems such as performance characteristics or sensitivity reduction, can be evaluated using live data.

Click the magnifying glass on the top right, you can search for related PIDs based on keywords

Custom

The scan tool includes support to select and show multiple PIDs. Click Display All to display all PIDs
Combine
The scan tool includes support to select multiple PIDs and click Combine to combine different graphs into one chart.

Data recording
The scan tool supports recording the current data values in the form of text. You can view the recorded files in Reports->Data Replay.

Pause
Click this button to pause the recording timeline

FREEZE FRAME

When the signal of the sensor is abnormal, the ECU will save the data at that moment of failure to form a freeze-frame. It is usually used to analyze the reasons that may lead to component(?) failures. The live data items supported by vehicles of different brands are not the same, so the freeze frames displayed when diagnosing vehicles of different brands may also be different. Some vehicles may not have the option of a freeze-frame which means that the model does not support this function.

Take Renault Duster ii ph as an example. After selecting the system to enter the lower freeze frame menu, the device will list all the fault codes under the system. Users can click on a fault code, such as DF1068 to view the freeze frame recorded by the car when the fault code occurs, including context when the fault appeared, and current context and additional data.

Context when fault appeared: record the live data when fault appeared to help the user to know the vehicle status. *Some vehicles don’t support this function; users will get a prompt when they click the menu.
Current context : Displays the current live data stream associated with the DTC
Additional data : record other data related to the fault

ACTUATION TEST (BI-DIRECTIONAL CONTROL)

Actuation test, also known as bidirectional control, is a generic term used to describe sending and receiving information between one device and another. This function is used mainly to judge whether these actuating components of the engine are working properly.

The vehicle engineers responsible for designing computer control systems programmed them so a scan tool could request information or command a module to perform specific tests and functions. Some manufacturers refer to bidirectional controls as functional tests, actuator tests, inspection tests, system tests or the like. Reinitialization and reprogramming also can be included in the list of bidirectional controls.   This function allows the device to send information to and receive information from, vehicle control modules. For example, in the case of OBD II generic information Mode 1 (which relates to data parameters), the scan tool user initiates a request for information from the powertrain control module (PCM), and the PCM responds by sending the information back to the scan tool for display. Most enhanced scan tools also can actuate relays, injectors and coils, perform system tests, etc. Users could check the individual part to see what is working properly by actuation test.

SPECIAL FUNCTIONS

Usually, special functions provide various reset or re-learning function menus for most vehicle systems. You can easily and quickly solve some faults through special functions for your car. After some functions are successfully executed, fault codes will be generated, which need to be cleared manually after the car is running for a little while which could include a single start of the engine or multiple warm up cycles.
Under each system, you can view the special features supported by that system. Different models and systems often have different special functions. Even for the same system of the same model, the years and ECU type may lead to different special functions supported.
