About car diagnostic tools

It is common for cars to develop problems and if you want your car to be in perfect working order then you need to diagnose your problems. For easy understanding, car diagnostic tools can be classified into two main groups: low-tech and high-tech tools.

Low-tech diagnostic tools

These are ideal for older cars that are not computer controlled. Some of the basic tools that are included in this category are: 12V Test Light, Timing Light, Vacuum Gauge, Mechanical Stethoscope, Vacuum Pump, Fuel Pressure Gauge, Leak Detector, and Compression Gauge.

High-tech tools

Two main categories of high-tech diagnostic tools are: scan tools and code readers. Code readers are the most basic computer tools used to extract codes from the car's computer. When the code is extracted, you can have a starting point for your diagnostic procedure.

In addition to helping you extract codes, car code reader also give you basic access to live or frozen data from your car computer.

The scanning tools, on the other hand, are code readers but with additional functionality. Basic scanning tools allow you to read and erase codes from car computers. The tools also allow you to view all the data available on the car computer.

Scanning tools have also been shown to have the ability to provide you with more information about codes.

You should be aware that the information displayed by the tools depends on the quality of the tool; therefore if you have a high quality tool you will see a lot of information; however, if you have a low-quality tool, you will have access to basic information. You should be aware that scanning tools that provide more information are usually more expensive.

While code readers and scan tools are the most important high-tech diagnostic tools, there are others, like multimeters, that are great. A multimeter is a device that is used to check problems in the electrical system of the car. For example, you can use it to check whether the item in your heated O2 sensor is good or not.
