EOBD SOFTWARE DEMONSTRATION

Initial display

The following picture (Picture 1) illustrates the initial display of the program.

Picture 1: The initial display of the program.

To communicate with the vehicle, the user must connect the diagnostic 16-pin plug to the diagnosis 16-pin fuse of the vehicle.It is important that the ignition switch is ON, so as to have electricity power on the ECU. The green LED on the diagnostic connector will turn on.

By clicking the "Start..." button at the upper left corner of the window, the user can select one of the three communication methods that are available. This selection depends on the communication protocol used by the vehicle. During the data transmission process between the diagnostic program and the vehicle's ECU, the red LED on the diagnostic connector blinks, confirming the process.

As soon as communication with the vehicle has been established, the screen display looks like the one illustrated in Picture 2 and contains the following frames:

Vehicle Status: This frame indicates the status of the "Check Engine" indicator lamp. The green color means that the indicator lamp is off, and no trouble codes have been stored in the vehicle's ECU. When there are stored fault codes (that cause the illumination of the indicator lamp), the color changes to red, while the number of the stored faults is shown.

Supported Tests: The systems that can be tested on the vehicle are presented here. Depending on the vehicle's manufacturer, they may be more than those specified by the European Committee.

Continuously Monitored Systems: In this frame the user can view the systems that are continuously monitored by the vehicle ECU, so as to provide the capability of fault code recording, as well as to ensure that all tests have been completed.

Fuel Systems: In this frame you can view the status of the fuel systems, when the vehicle is equipped with more than one independent fuel systems, for example when there are two oxygen sensors present before catalyst.

Ox Sensor Position: Here the user can be informed about the existance of more than one oxygen sensors before the catalytic converter. This could happen on V or Boxer engines (one oxygen sensor per cylinder bank) or engines with 4-2-1 exhaust manifolds.

Picture 2: The display of the program after establishing communication with the vehicle.

Live Data

This screen (Picture 3) illustrates live data in real time. You can see data refreshing and it is possible to freeze data values for further evaluation. Then, by clicking Refresh.., all data values refresh.

Picture 3: Live Data display.

Freeze Frame Data

This screen (Picture 4) enables you to obtain some additional information about a stored fault at the moment of its appearance, such as vehicle speed, engine load, engine rpm etc., provided that this is supported by the vehicle itself.

Picture 4: Freeze frame data.

Oscilloscope

On this screen (picture 5), you can monitor, both graphically and numerically, the function of the sensors that are being checked, in real time. This is very important for sensors such as oxygen sensor, throttle position sensor, manifold absolute pressure (MAP) sensor etc. By examining those sensors, you can see if they are responding properly or not, even if there is no stored fault.

Picture 5: Oscilloscope.

The user can select from a table the sensors to be checked. On the main part of the screen you can see a graph of the sensors' output as a function of time, while on the lower part you can read the output value and its normal operation limits. It is important that this function of the diagnostic program enables you to monitor up to 5 sensors simultaneously. By combining those data you can make some useful conclusions about vehicle condition (for example engine load / MAP sensor output, engine speed / ignition spark timing / throttle position sensor, etc.).

Oxygen (λ) sensors

This screen (Picture 6) gives you a guide of the voltage output of a typical oxygen sensor as a function of time, in order to have a reference for its correct voltage in conjunction with the air/fuel ratio (rich or lean), its switch time etc.

Notice: The original displays of the product may be slightly different from the ones presented in this demonstration.

HARDWARE

For EOBD communication with the vehicle, you need only one hardware device: the 16-pin Electronic Connector (corean - european - japanese vehicles), which is shown in the picture on the left.
This connector has 16-pins as indicated by the EOBD standardization, and two built-in leds, which inform you if the connector has power (green LED) and when data is being exchanged between your computer and the car's processor (red LED).

REQUIREMENTS

To be able to use our products, you must have a PC with the following specifications:

Minimum System Requirements

Processor: Pentium^® I, 233 MHz or equivalent
