![]() ![]() Returns numerous data, including Drive Condition ID and Engine Speed*ī5 is Engine Idle RequestB6 is Engine Stop Request*ģ codes per message frame, BCD encoded. Similar to PID 13, but = Ī0 = Power Take Off (PTO) status (1 = active) not usedĭistance traveled with malfunction indicator lamp (MIL) onįuel Rail Pressure (relative to manifold vacuum) (Includes malfunction indicator lamp (MIL) status and number of DTCs.) If Mode 2 PID 02 returns zero, then there is no snapshot and all other Mode 2 data is meaningless. The exceptions are PID 01, which is only available in Mode 1, and PID 02, which is only available in Mode 2. 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 last diagnostic trouble code was set. 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. The expected response for each PID is given, along with information on how to translate the response into meaningful data. The table below shows the standard OBD-II PIDs as defined by SAE J1979. Vehicle manufactures are not required to support all modes.Įach 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 a HEV). Control operation of on-board component/system Show pending Diagnostic Trouble Codes (detected during current or last driving cycle) Test results, other component/system monitoring (Test results, oxygen sensor monitoring for CAN only) Test results, oxygen sensor monitoring (non CAN only) Clear Diagnostic Trouble Codes and stored values They are, the $ prefix indicating a hexadecimal number: There are ten modes of operation described in the latest OBD-II standard SAE J1979.
