Parameter Identification (PID) Access

The PID mode allows access to certain data values, analog and digital inputs and outputs, calculated values and system status information. This includes analog and digital signal inputs and outputs along with calculated values and system status. There are two types of PID lists available. The first is the Generic OBD II PID list. This is a standard set of PIDs for all manufacturers which all scan tools musts be able to access. The second is a Mazda specific list which can be accessed by the NGS Tester. When accessing any of these PIDs, the values will be continuously updated. For a complete list of all PIDs, Refer to POWERTRAIN CONTROL MODULE (PCM) INSPECTION.
