OBD Diagnostics for Long-Term Vehicle Health Scoring and Predictive Ownership

OBD diagnostics go beyond fault codes—they enable long-term vehicle health monitoring. By tracking trends, owners can predict problems before failures occur.

What Is Vehicle Health Scoring?

Data Used in Health Analysis

• Fuel trim trends

• Temperature stability

• Misfire counts

• Voltage consistency

How Health Scores Are Built

Multiple parameters are combined into:

• Reliability indicators

• Maintenance forecasts

• Risk assessments

Predictive Maintenance Using OBD

Early Warning Signs

• Gradual efficiency loss

• Increasing correction values

• Temperature drift

Advantages Over Reactive Repairs

• Reduced downtime

• Lower repair costs

• Planned maintenance

Benefits for Owners and Fleets

• Better resale decisions

• Extended vehicle lifespan

• Improved cost control

• Higher reliability

Conclusion

OBD health scoring transforms diagnostics into a predictive ownership tool.
