PID/Data Monitor and Record

The PID/Data monitor and record option allows the IDS or equivalent tester 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 and resistances calculated by the restraints control module (RCM) and occupant classification sensor (OCS) and sent to the IDS or equivalent tester for display. Many of the PIDs supported by the modules are calculated periodically and are, therefore, not true real time readings.

To retrieve PIDs, follow these steps:

1. Connect the IDS or equivalent tester to the data link connector (DLC).
2. Turn the ignition switch to the ON position.
3. Follow manufacturer's instructions for the IDS or equivalent tester being used.
4. Select either the RCM or OCs module.
5. Record all PIDs that are to be retrieved and initiate PID retrieval. PIDs are updated continuously on the display.
