PID/Data Monitor Item Table

PID/DATA MONITOR ITEM TABLE

Description

The PID mode allows access to PCM information. This includes analog and digital signal inputs and outputs along with calculated values and the system status. There are 2 types of PID lists available and both are used throughout this information. The first is generic (J1979) OBD PID list. This is a standard set of PIDs that all scan tools must be able to access. The second is a Mazda-specific (J2190) list which can be accessed by an appropriate scan tool. When accessing any of these PIDs, the values are continuously updated. The generic or Mazda PID list provides definitions and values in appropriate units. For more information, refer to the Society of Automotive Engineers (SAE) document J2205.

Generic OBD PID List

An X in the Freeze Frame column denotes both a mode 1 and mode 2 PID (real time and freeze frame).

Generic OBD PID List (Part 1):

Generic OBD PID List (Part 2):

- 1 OL = Open Loop, have not satisfied conditions for closed loop.
- 2 Percent engine load adjusted for atmospheric pressure.
- CL = Closed loop using HO2S(s) as feedback for fuel control
- OL DRIVE = Open loop due to driving conditions (heavy acceleration).
- OL FAULT = Open loop due to fault with all upstream HO2S sensors.
- CL FAULT = Closed loop fuel control, but fault with one upstream HO2S sensor on dual bank vehicles.
