Parameter Identification (PIDs)

PID/DATA MONITOR AND RECORD

The PID/Data Monitor and Record option allows the diagnostic tool operator to read the state of several parameter IDs (PIDs) to aid in diagnosing the system. PIDs are real time measurements of parameters such as voltages, resistances, etc., calculated by the RCM and sent to the diagnostic tool for display. Many of the PIDs supported by the RCM are calculated periodically and are, therefore, not true real time readings. The following is a table of supported PIDs, expected range and units of measurement.

To retrieve PIDs, follow these steps:
1. Connect the diagnostic tool to DLC.
2. Turn the ignition switch to the RUN position.
3. Follow manufacturer's instructions for the diagnostic tool being used.
4. PIDs are continuously updated on the display.
