PARAMETER IDENTIFICATION
Parameter Identification (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 EEC-V specific PID list that can be accessed by using World Diagnostic System (WDS) scan tool. When accessing any PIDs from the specific PID list, the values are continuously updated.
