All light duty vehicles (i.e. less than 8,500 pounds) sold inNorth Americasince 1996, as well as medium duty vehicles (i.e. 8,500-14,000 pounds) beginning in 2005, and heavy duty vehicles (i.e. greater than 14,000 pounds) beginning in 2010,citation neededare required to support OBD-II diagnostics, using a standardizeddata link connector, and a subset of the SAE J/1979 defined PIDs (or SAE J/1939 as applicable for medium/heavy duty vehicles), primarily for state mandatedemissionsinspections.Typically, anautomotive technicianwill use PIDs with ascan toolconnected to the vehicles OBD-II connector. The technician enters the PID The scan tool sends it to the vehiclescontrollerarea network(CAN)-bus, VPW, PWM, ISO,KWP. (After 2008, CAN only) A device on the bus recognizes the PID as one it is responsible for, and reports the value for that PID to the bus The scan tool reads the response, and displays it to the technicianContents Modes Standard PIDso Mode01o Mode02o Mode03o Mode04o Mode05o Mode09o Bitwise encoded PIDs Mode 1 PID00 Mode 1 PID01 Mode 1 PID41 Mode 1 PID 78 Mode 3 (no PID required) Mode 9 PID 08 Mode 9 PID 0Bo Enumerated PIDs Mode 1 PID03 Mode 1 PID12 Mode 1 PID1C Fuel Type Coding Non-standard PIDs CAN (11-bit) bus formato Queryo Response See also References External linksModesEditThere are ten modes of operation described in the latest OBD-II standard SAE J1979. They are as follows:Mode (hex)Description01Show current data02Show freeze frame data03Show stored Diagnostic Trouble Codes04Clear Diagnostic Trouble Codes and stored values05Test results, oxygen sensor monitoring (non CAN only)06Test results, other component/system monitoring (Test results, oxygen sensor monitoring for CAN only)07Show pending Diagnostic Trouble Codes (detected during current or last driving cycle)08Control operation of on-board component/system09Request vehicle information0APermanentDiagnostic Trouble Codes(DTCs) (Cleared DTCs)Vehicle manufacturers are not required to support all modes. Each manufacturer may define additional modes above #9 (e.g.: mode 22 as defined by SAE J2190 for Ford/GM, mode 21 for Toyota) for other information e.g. the voltage of the traction battery in ahybrid electric vehicle(HEV).1Standard PIDsEditThe table below shows the standard OBD-II PIDs as defined by SAE J1979. The expected response for each PID is given, along with information on how to translate the response into meaningful data. Again, not all vehicles will support all PIDs and there can be manufacturer-defined custom PIDs that are not defined in the OBD-II standard.Note that modes 1 and 2 are basically identical, except that Mode 1 provides current information, whereas Mode 2 provides a snapshot of the same data taken at the point when the lastdiagnostic trouble codewas set. The exceptions are PID 01, which is only available in Mode 1, and PID 02, which is only available in Mode 2. If Mode 2 PID 02 returns zero, then there is no snapshot and all other Mode 2 data is meaningless.When using Bit-Encoded-Notation, quantities like C4 means bit 4 from data byte C. Each bit is numerated from 0 to 7, so 7 is the most significant bit and 0 is the least significant bit.ABCDA7A6A5A4A3A2A1A0B7B6B5B4B3B2B1B0C7C6C5C4C3C2C1C0D7D6D5D4D3D2D1D0Mode01PID(hex)Data bytes returnedDescriptionMin valueMax valueUnitsFormulaa004PIDs supported 01 - 20Bit encoded A7.D0 = PID $01.PID $20See below014Monitor status since DTCs cleared.
