The onboard diagnostics system (OBD-II) uses Parameter IDs (PIDs) to request data from the vehicle. There are standard PIDs that every scanner can read (like engine RPM or vehicle speed).
Proprietary software relies on strictly formatted initialization files (such as .ini , .json , or .xml ). If a power surge or improper shutdown cuts off a write cycle, these files become unreadable. Locate the installation directory of the affected software.

When a scan tool communicates with a vehicle, it sends requests using hex codes called PIDs (Parameter IDs).
Verify mapping between the data source and the reporting module. If a power surge or improper shutdown cuts
This deep-dive technical article explores why this code occurs, the underlying data ecosystems that generate it, and how fleet managers and station operators can resolve it. The Anatomy of Fleet Card Transactions
