The expected response for each PID is given, along with information on how to translate the response into meaningful data.

The real time (Live Data) vehicle operating information (values/status) that the vehicle’s computer supplied to the Scan Tool for each sensor, actuator, switch, etc., is called Parameter Identification (PID) Data. The “Mode 01” data stream is defined as the “Live Data” stream, which indicates “real time” sensor readings and switch status of the vehicle’s systems. The scan tool modes and other OBD2 requirements are defined in a document called SAE J1979. The Society of Automotive Engineers (SAE) created guidelines for managing this information, and developed a list of 'diagnostic modes' that scan tools would need to support. Follow the on-screen instructions to download and install the upgrade.Ī: When Onboard Diagnostics II (OBD2) was first conceived as a means of monitoring vehicle emissions, it was obvious there would be a significant amount of information to manage and monitor.
