You can also send the codes to your mechanic for evaluation. Once you have the codes from your code reader, you can research the diagnostics data online or in the mechanical manual for your car. The OBD2 scanner is a simple and effective tool to use. Automotive voltmeters read the electrical system of the car and test relays and fuses. This code reader provides stats and sends the results to PC software. Another tool is the Bluetooth scanner, which also plugs into the car.
The end of the tool plugs into a fitting under the driver's side dashboard.
One of these diagnostic tools is an OBD2, or on-board diagnostic, hand-held scan tool.
There are several types of diagnostic tools available, including scan tools you can hold and those that work wirelessly. No matter your mechanical experience, the check engine light doesn't have to be daunting. These can help you determine what may be the problem, and if it requires going to a mechanic. When you're not sure what's wrong with your car, an automotive diagnostic scan tool may help.
