Urgency
Make it clear to stop immediately, inspect as soon as possible or observe; safety related signals always take priority.
AI VEHICLE FAULT TRIAGE
AI fault triageAssess the risk first.Then decide whether to keep driving.
Abnormal noise, vibration, leakage or other abnormalities can be directly described without a fault code. AI will combine the vehicle model, power type, mileage, fault occurrence conditions and recent maintenance records to first classify risks and then sort out the key points for inspection and maintenance communication.
One important principle
A trouble code identifies an abnormal condition detected by the vehicle. It does not prove that a specific part has failed. OBD data is diagnostic evidence, not a final diagnosis.

WHAT YOU GET
A preliminary screening to sort out six key pieces of information
Possible cause sequence
Use "more likely, possible, need to be eliminated" to express the relative order and do not falsify the precise probability.
Car owner safety self-examination
Only observation items that do not require disassembly, contact with high temperatures, high voltage electricity and leaking liquids are listed.
Maintenance shop key inspections
Organize communication checklists such as freeze frames, live data, electrical, pressure or mechanical inspections.
Approximate cost range
Estimates are based on preset maintenance project intervals, and AI guesses are not regarded as quotations.
Must be professionally confirmed
Make it clear which conclusions must be confirmed by manufacturer's information, professional equipment and actual testing.
COMMON OBD CODES
Common OBD trouble codes
If there is a code, you can check it first to determine the meaning; if there is no code, just describe the symptoms above.
BEFORE CLEARING CODES
Before clearing the code, save the diagnostic evidence first
- Save all code reportsInclude the current code, the pending code and the permanent code. Don’t just record the first one.
- Save freeze frameRecord the rotation speed, load, water temperature, vehicle speed and fuel correction when reporting the code.
- Record fault light statusSteady light and flashing represent different risks, while recording jitter, abnormal noise, odor and power changes.
OBD FAQ
OBD trouble code frequently asked questions
Can a trouble code identify a failed part?
No. A code identifies an abnormal system, monitoring condition, or signal relationship. A diagnosis also needs related codes, freeze-frame data, live data, and physical testing.
Can I still drive it if the engine check light is on?
Stop the vehicle when the fault light flashes or is accompanied by severe shaking, sudden power drop, excessive water temperature, smoke or strong odor. When it is always on and running smoothly, it is only recommended to be cautious and take a short trip for inspection.
Why is it not recommended to clear the code immediately?
Clearing the code or powering off may clear the frozen frame and part of the self-learning information at the same time, making intermittent faults more difficult to reproduce. Diagnostic information should be saved completely first.
