In order to meet different types of vehicle fault diagnosis interface, we designed flexible drive circuit after comprehensive analysis of structural features about all currently existing vehicle fault diagnostic interface communication circuit in the process of designing auto diagnostic tool. The so-called flexible drive circuit is a drive circuit that can configure flexibly. All kinds of structure elements have been preset in system and…

If you see a "check engine" or a "service engine soon" light in your instrument cluster; your car has stored a diagnostic trouble code. This means the computer system on your vehicle has detected a problem with the various systems it controls. Your car has many different sensors that monitor the various vehicle systems.



If the trouble code light has been illuminated your vehicle enters into "limp mode" this means it is running on a predetermined program that causes poor mileage…

Today's car is a very advanced machine. Long gone are the days when your mechanic would take the whole day inspecting the engine and other components in order to diagnose the vehicle's fault. With the installation of the car computer on most vehicles, diagnoses have become simpler and faster.



Most vehicles manufactured between 1992 and 1995 have an On Board Diagnostics I (OBD I) facility while those manufactured after 1996 have the OBD II. OBDs are defined as the electronic…

On most vehicles the connector is located at the driver's compartment. Once the diagnostic code scanner is plugged in you can retrieve auto diagnostic codes the engine computer has stored in its memory. These auto diagnostic codes are the same codes the dealer and repair shops use to replace sensors and clear codes.



Correct computer system function is essential for your car's engine to operate properly. Many engine run-ability problems can be…

Basic setting method and steps

The whole control system of a vehicle is composed of many subsystems (sensors, actuator elements, power supply, controller) circuit composed. Therefore,…

In actual use, different vehicles can use the same diagnostic connector, such as OBD II, but pin of diagnosis signal might be distributed in different pins. In order to be compatible with different pins, output connector DB15 internal connection channel switching matrix of car diagnostic tool can realize arbitrary switching of 2-way 13 channels through channel switching matrix.

 Change-over switch…

Public data line is used for connection to F3-D truck scanner, Data line is used for communication with ECU as well as information communication with other vehicle electronic devices, such as electronic instrument panel and other devices. Some engines have two public data lines: one is in the whole wiring harness (engine side data line); another is separated from ECU harness,…
