OBD-II software resource for and users


. or OBD-II PIDs On Board “Parameter IDs”, are codes to request data from a used as a diagnostic tool. codes are part of SAE standard required to be implemented in all cars in North America since

Typically, an automotive technician use PIDs with a scan connected to the vehicle’s OBD-II

The technician enters the PID

The scan sends to the vehicle’s bus (CAN, PWM, ISO, KWP. 2008, CAN only)

A device on the bus the PID as one it is responsible for, and reports the for that PID to the bus

The scan tool the response, and shows it to the technician

There are ten modes of operation in the latest OBD-II standard SAE They are, the $ prefix a hexadecimal number:

$01. Show current

$02. Show freeze data

$03. Show Diagnostic Trouble Codes

The table below the standard OBD-II PIDs as by SAE J1979. The expected response for PID is given, along with on how to translate the response into data. Again, not all vehicles support all PIDs and there can be custom PIDs that are not in the OBD-II standard.

Note that modes 1 and 2 are identical, except that 1 provides current information, Mode 2 provides a snapshot of the data taken at the point the last diagnostic trouble was set. The exceptions are PID 01, which is available in Mode 1, and PID 02, which is available in Mode 2. If Mode 2 PID 02 zero, then there is no and all other Mode 2 data is
