Matco Tools Automotive Code Readers and Scanners

Running a diagnostic test with a code reader can help pinpoint problems with your engine. Matco Tools makes a variety of scanner products that can help you discern where things have gone wrong inside an automotive system. Having a code reader or scanner available can also help you make decisions about the type of repair your vehicle requires.

What does a Matco Tools code reader do?

Code readers are computer diagnostic tools that use auto codes to identify problems in a car's system. These tools also allow the mechanic to clear the diagnostic data once it has been written down or addressed. Auto codes are associated with specific areas of the engine and can indicate parts that require a repair or replacement. By resetting the code reader, you can turn off the check engine light and remove the data that was just accessed. Once the tool is reset, you can verify the accuracy of your repair by running another scan.

What does a Matco Tools scanner do?

Scanners can read diagnostic codes and clear them just like a code reader tool. Scanners may also include:

  • Advanced playback and data reading features.
  • Built-in scan and testing equipment.
  • Extensive databases filled with diagnostic procedures and information about troubleshooting.
  • Smartphone or tablet interfaces.
How do you use a code reader on a vehicle?

When you scan your engine with a Matco Tools product, you will know what is wrong without having to turn to a professional mechanic. Plug the code reading device into the computer system of your car or truck, and it will return an automotive repair code. Auto repair codes may be standard or specific to a manufacturer and model. An owner's manual can tell you where to plug in your tool when the connection is hidden or difficult to see. Here are some basic steps to follow to begin scanning your car or truck:

  • Find a tool that is designed for the specific year, make, and model of your vehicle. Cars made before 1996 require an OBD-I reader. Vehicles produced after 1996 will require an OBD-II diagnostics device.
  • Turn off your car.
  • Locate the diagnostics connection on your automobile. Look for a rectangular or trapezoid plug with sixteen pins in two rows of eight. OBD-I connections can be found in a variety of locations, including under the dashboard, near a fuse block, or in the engine compartment. OBD-II connections are usually located to the left of the steering column and under the dashboard.
  • Slide the reader's plug into the connector and make sure the connection is snug.
  • Turn on your vehicle to engage the tool and begin the scan.
  • Supply any data the device requests. Some readers will ask for the make and model information or the VIN.
