OBD stands for On-board Diagnostic, a standard jointly established by SAE and ISO, defining the standard method of exchanging digital data between the computer system installed on the car. Related to exhaust emissions (Emission) and data scanners, both in terms of hardware, software, installation location, detected malfunction code (Malfunction Indicator Light: MIL) and display it to the driver or mechanic to know the problem. In 1988, the California Air Resources Board (CARB) has set a requirement that all cars must have a system that can distinguish between exhaust emissions (emission system) and engine control system (powertrain system), which is called the OBD-I system. Meanwhile, CARB has established the OBD-II standard and made it mandatory for all cars in the United States since 1996 to provide new guidelines for mechanics in solving engine and emission control system repair problems. The data obtained from OBD-II devices is divided into 3 main groups: 1. DTC (Diagnostic Trouble Code) refers to diagnostic trouble codes used to predict the damage that has occurred. For example, when the diagnostic trouble code is read as P0068 according to the specified standard, it means that the fuel temperature is too high, etc. 2. Real-time operation data is data obtained from the engine operation sensor to measure the efficiency of the operation or to process the damage along with the DTC code or other data such as engine speed, radiator temperature, common rail pressure, whether the problem occurred while the car was running or not (each model and brand of car will have different values). 3. Operation data for each period is reading real-time data at the beginning of the time cycle and locking that data until the time cycle is complete before reading the data again. This information is used to adjust the engine's performance. OBD-II Protocol The automotive industry has collaborated with The Society of Automotive Engineers (SAE) to establish technical standards and regulations for OBD-II. These standards define the format of the data to be communicated, the testing methods, and the definition of diagnostic trouble codes that are the same for all vehicles regardless of the make or model of vehicle. The communication standards or protocols used in OBD-II devices are modified or added for each vehicle manufacturer. But if summarized, it can be divided into 4 main groups: 1. ISO 9141 has a transmission speed of 10kb/s, used with most European and Japanese cars. 2. J1850 PMW (Pulse Width Modulation) has a transmission speed of 100kb/s, used in Ford and Mazda cars. 3. J1850 VPM (Variable Pulse Modulation) has a transmission speed of 100kb/s, used with GM cars. 4. CAN (Controller Area Network) has a transmission speed of 1-10Mb/s, used with cars launched in 2008. Different protocols cannot be used together because they are different in terms of hardware, electrical signal level and software. ***The characteristics of the OBD-II plug will be the same standard with the same pin definition.
