Data Logger PID/Data

DATA LOGGER PID/DATA

The parameter ID (PID)/Data Monitor and Record option allows the scan tool operator to read the state of several PIDs to aid in diagnosing the system. PIDs are real time measurements of parameters such as voltages, resistances, etc., calculated by the restraints control module (RCM) and sent to the scan tool for display. Many of the PIDs supported by the RCM are calculated periodically and are, therefore, not true real time readings.

To retrieve PIDs, follow these steps:
1. Connect the scan tool to the data link connector (DLC).
2. Turn the ignition switch to the ON position.
3. Follow the manufacturer's instructions for the scan tool being used.
4. Select RCM.
5. Select DATA LOGGER.
6. Record all PIDs that are to be retrieved and initiate PID retrieval. PIDs are updated continuously on the display.
