PIDs can be retrieved with a scan tool or a data logger.

Explanation:
PIDs are the data points the vehicle’s ECU can report. You can retrieve them in real time with a scan tool, which queries the ECU and shows live values. You can also record them over time with a data logger, capturing the same PIDs for later analysis. Both methods access the same ECU data stream via OBD-II or CAN, so PIDs can be retrieved by either device. Therefore the statement is true. Limiting retrieval to only one device would be incorrect, and saying you cannot retrieve them would also be incorrect.
