Have you ever found yourself stranded on the side of the road, the engine sputtering and your heart pounding, wondering if you’ll ever reach your destination? A common reason for breakdowns in older vehicles is a faulty electrical system. Understanding how to diagnose and repair these issues can save you a lot of stress and money in the long run.
What is OBD?
OBD stands for On-Board Diagnostics. It’s a system built into most vehicles since 1996 that allows mechanics and technicians to access and interpret diagnostic trouble codes (DTCs). These codes provide insights into why your car is experiencing problems, giving you a roadmap for fixing it.

From simple sensor malfunctions to complex engine issues, understanding OBD codes can help you pinpoint the source of the problem and find the right solution.
