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.
The On-Board Diagnostic (OBD) Test is divided into three special tests: Key On Engine Off Self-Test (KOEO), Key On Engine Running (KOER) Self-Test and Continuous Memory DTCs Self-Test. The OBD test checks the integrity and function of the powertrain control system and outputs the test results when requested by the WDS or equivalent. It also provides a quick end check of the powertrain control system. It is usually performed at the start of each diagnostic procedure with all the accessories off and is performed at the end of most troubleshooting tests for verification of repair and to make sure no other faults were incurred while servicing a previous fault.
