OBD is the acronym for Onboard Diagnostics, the standardized system in vehicle computers that allows cars and trucks to run diagnostics. It was developed and adapted to strict specifications by the Society of Automotive Engineers. OBD-II is the standard in all vehicles manufactured in 1996 or later. It differs from the older ODB1 in that the 1996 standard implements protocols, error codes, and connectors supported by all vehicle manufacturers. This means that a single OBD2 scanner can retrieve diagnostic codes from any vehicle made in 1996 and beyond.
How OBD2 Works
Because they follow a specific set of standards, OBD2 scan tools are easy to use. They fit the same connector, which is present in all vehicles, as defined by SAE standard J1962. Often these connections are located under the dashboard near the driver’s seat, depending on the vehicle make.
Typically, the scanner is simply plugged into the connector, the vehicle is powered on (but not started), and you follow the simple menu on the display to retrieve any diagnostic codes saved to the onboard computer. These codes remain in memory until the problem is fixed or they are deliberately cleared.
Professional-level scan tools have much greater capabilities, and require some training. Diagnostic technicians can do much more, such as perform specific bi-direction tests on running vehicles, or connect to OEM-specific devices and controls to get feedback that won’t normally generate error codes.
If your Check Engine light is on, or your vehicle has been running rough, an Auto Scanner Tool can help you identify the problem. It’s definitely a good thing to keep handy. While you’ll have to spend thousands to get the diagnostic capabilities of a good auto shop, there are a number of OBD2 readers that are very affordable. Here are five of the most recommended diagnostic tools.
