Data Logger PID/Data

DATALOGGER PID/DATA

The DataLogger PID/Data 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 and resistances, calculated by the restraints control module (RCM) sent to the scan tool for display.

To retrieve PIDs, follow these steps:
1. Connect the scan tool to the DLC.
2. Turn the ignition switch to the ON position.
3. Follow the manufacturer's instructions for the scan tool being used.
4. Select DataLogger.
5. Select RCM.
