Application Areas Of OBDII
The introduction of the latest OBDII products launched by Jingbang Technology can be applied to three fields: individuals, enterprises, and 4S stores
Individual users: It is convenient to manage their own vehicles, facilitate the evaluation of vehicles and save costs; at the same time, it also increases the understanding of vehicle driving habits, safe operation skills, and car knowledge.
4S shop users: OBDII can be installed on the user's vehicle to form a remote service diagnosis network. OBDII can provide detailed vehicle data, thus realizing vehicle remote diagnosis service and improving the service quality of enterprises to customers. When the user's car breaks down, the rescuers of the 4S store can also obtain the real-time location information of the faulty vehicle and arrive at the scene in a timely and accurate manner.
OBDII is an on-board automatic diagnosis system, which is a terminal product that detects the operating parameters of various systems of the car and reads the data. It is to integrate the inspection, maintenance and management of automobiles to meet the requirements of environmental protection. The OBD system will enter the engine, gearbox, ABS and other system ECUs (computers) to read fault codes and other related data, and use a small vehicle communication system. For example, the GPS navigation system or wireless communication is used to automatically notify the vehicle's identity code, fault code and location and other information to the management equipment and platform.
How OBDII Works
When the car is in normal operation, the input and output signals (voltage or current) of the electronic control system of the car will change regularly within a certain range; when the signal of the electronic control system circuit is abnormal and exceeds the normal variation range, And this abnormal phenomenon will not disappear within a certain period of time (3 consecutive strokes), the ECU judges that this part is faulty, the fault indicator lights up, and the monitor stores the fault in the internal RAM in the form of a code ( Random Access Memory: Random Access Memory), the stored fault code can be read by fault display light or OBD II scanner during maintenance. If the fault no longer exists, the monitor will instruct the fault display light to go out after it has not received the relevant signal for 3 consecutive times. After the fault display lamp goes out, the engine warm-up cycle is about 40 times, and the fault code will be automatically cleared from the memory.
