Using Module PID
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Electronic modules connected to a network usually offer diagnostic scan tool measuring of internal data or operating values. This data is known as a parameter ID or PID.
- Using a diagnostic scan tool, PID input values, output states, and diagnostic states may be read.
- Monitoring PID information in the datalogger function of the diagnostic scan tool allows detailed, accurate testing without vehicle disassembly and cumbersome equipment.
- Datalogger displays are the "behind the scenes" information for almost every function on a modern vehicle.
- Controlling most module outputs with a PID is possible. For example, an output state command PID for a cooling fan, engine RPM, and many other module outputs are commonly available.
