Parameter Identification (PID): Description
WARNING: This page is about a different car, the 1998 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
PID mode allows access to certain data values, analog and digital inputs and outputs, calculated values, and system status information. There are 2 types of PID lists available. The first is Generic OBD-II PID list. This is a standard set of PIDs that all scan tools can access. The second is a Ford specific PID list that can be accessed by using New Generation Star (NGS) scan tool. When accessing any PIDs from the specific PID list, the values are continuously updated.
