Car diagnostic tools are used by professional mechanics and car owners to help them figure out what’s wrong with their vehicles. They connect to a vehicle’s onboard diagnostic (OBD) port and communicate with a computer program to display information about what is going on inside the car. They can also provide instructions on how to fix the issue.
There are a variety of different car diagnostic tools available on the market, from basic code readers to full-blown scanners and analyzers. Using these tools can help a mechanic identify and troubleshoot problems more efficiently. The type of car diagnostic tool a mechanic uses will depend on the complexity of the problem at hand and the level of expertise required to solve it.
A basic code reader, sometimes called an OBD-II generic tool triage tool, can quickly read and clear engine or PCM codes. These tools are best for a quick diagnosis of the vehicle’s issues and are commonly used to address check engine lights. The code reader will also give a basic description of the engine or system code in question to help the mechanic determine what the problem might be.
Some more advanced scanners can record and compare live data from multiple sensors. These tools can help to determine what is causing the vehicle to run poorly, such as air flow or fuel economy issues. They can also help diagnose more serious problems, like a leaky gas tank or transmission issues.
Other diagnostic tools can also monitor the internal temperature of a vehicle. A noncontact infrared thermometer can be used to check for things such as a broken coolant sensor or a thermostat that is overheating and restricting airflow. These are issues that can be easily fixed with a simple tool and could greatly improve the performance of the vehicle while reducing fuel costs.
Most automotive diagnostic tools require the user to enter a vehicle identification number before they can begin to scan for errors. This number is located on a sticker that is normally in the lower corner of the windshield on the driver’s side or under the hood next to the engine. Some scanners will ask for this information before displaying any OBD2 error codes while others will automatically pull this information from the car’s onboard system.
There are also professional diagnostic tools that combine a scope and meter into one piece of equipment. These tools are typically too expensive for home mechanics to own, but can help a mechanic pinpoint a problem quickly and accurately.
