Dashboard DTC Hub is an independent automotive reference for dashboard warning lights and diagnostic trouble indicators. We compile information from OEM owner's manuals, SAE J2402 standards, NHTSA documentation, and certified technician field experience so drivers can understand what their dashboard is telling them — before it becomes a more expensive problem.
Every warning light on this site is documented from primary automotive sources. We cross-reference OEM documentation with SAE and NHTSA standards to ensure accuracy. Repair cost estimates are based on national averages from multiple data sources and may vary by location, vehicle condition, and shop rate.
This site is built for everyday drivers who see a warning light and need to know: Is this serious? Can I keep driving? What will it cost to fix? We provide clear, actionable answers — no mechanical knowledge required.
