Warning lights and fault codes
- Dashboard warning light meanings can vary by vehicle brand, model, year and market.
- An OBD-II fault code points to a system or condition, but it does not always identify the exact failed part.
- Diagnosis should include proper inspection, scan-tool data, service information and safety checks.
When to stop driving
If a red warning light appears, the vehicle overheats, brakes or steering feel unsafe, smoke appears, or the vehicle loses power severely, stop safely when it is safe to do so and seek professional help.
