All cars and light trucks built for sale in the United States after 1996 are required to be OBD-II compliant. There are five OBD-II prot

"Circuit/open circuit" is mostly used when fixed values or high or low detection of specific circuits is not feasible. It can also be used with both low and high fault codes, provided that all three circuit conditions are detectable.

As early as the early 1980s, many automakers in the developed countries of the automotive industry began to use EFI engines extensively.

The OBD interface is equipped within 1 meter of the driver's distance, usually below the dashboard or on the driver's side.

The first two bytes are the information part, the first one is the identifier, and the first 8 bits of the identifier are used as the receiving judgment, which should include the destination address of this packet.

The demands of automobiles in modern society are constantly increasing. These requirements include extremely high active safety and passive safety; comfort in riding; convenient and humanized driving

VIN is an abbreviation of English Vehicle Identification Number. Because the SAE standard stipulates that the VIN code consists of 17 characters, it is commonly called the seventeen-digit code. It contains information on the manufacturer, age, model, body type and code, engine code and assembly location of the vehicle. Correct interpretation of the VIN code is very important for us to correctly identify the model so that it can be properly diagnosed and repaired.

This correction applies to Google map China, Microsoft map china, MapABC, etc., because these maps are the same as the offset.dat file, which is 0.01 precision correction data. If you need it, please contact the website, non-free version.

BD is the abbreviation of English On-Board Diagnostics, and the Chinese translation is "Automatic Vehicle Diagnostic System".This system will monitor the car's exhaust gas from the runni

Turn the ignition key to the start position and if the “Service Engine” or “Check Engine” light is flashing briefly, your vehicle is equipped with an OBD system. Under normal circumstances, the "Service Engine" or "Check Engine" lights will automatically turn off after a short flash, indicating that everything is normal.

1, because EST527 has established a physical layer, data link layer and part of the application layer protocol for you, so as long as the OBD2 standard application layer protocol text, ISO15031-5 or SAE J1979 (the two protocols are the same content).

The bit synchronization of the CANBUS bus of the car is only generated when the node detects the transition from "recessive bit" to "dominant bit". When the edge of the jump is not

In the automotive electronics industry, CAN is used to connect engine control units, sensors, square brake systems, etc., with transmission speeds up to 1 Mbit/s. At the same time, CAN can be installed in automotive-themed electronic control systems, such as vehicle lights, Electrical windows, etc., are used instead of wiring wiring devices. CAN is a serial communication protocol, which can effectively support real-time control of segments with high security levels.

CANBUS adopts the structure of twisted pair self-checking, which can not only apply electromagnetic interference to the transmission of information, but also prevent external interference. The CAN system uses two high and low data lines, and the controller inputs the signal to colleagues. Two communication lines are sent, and the high and low levels are mirror images of each other. And each controller adds a terminating resistor, which has reduced the overshoot effect during data transmission.
