AI Fault Code Severity and Descriptions help fleet managers interpret Diagnostic Trouble Codes (DTCs) more effectively by leveraging onboard diagnostics (OBD-II) for light-duty vehicles and the J1939 protocol for heavy-duty vehicles. This feature leverages AI to provide actionable insights by:
-
Categorizing faults as High, Medium, or Low severity based on risk.
-
Translating complex fault codes into clear, human-readable descriptions.
-
Highlighting potential risks and suggesting resolution steps.
Important
Fault code severity and description are generated by AI and are experimental. Verify the accuracy of the information before taking any action.
Changes to settings may take time to sync in low-connectivity areas.
