Common Diagnostic Scanning FAQ’s
An automotive scan tool is an electronic tool used to interface with, diagnose, and sometimes reprogram the vehicle’s control modules.
The tool is connected to the vehicle’s data link connector, or DLC, and is used to read out diagnostic trouble codes, or DTC’s. Some scan tools will display live data stream, have bidirectional controls, and may be capable of calibrating or programming the modules within specific parameters.
Most typical scan tools, however, do not have the ability to fully reprogram modules because it needs specific software and a pass-through device.
It provides a quick and accurate assessment of your vehicle. A technician using a diagnostic scanning tool will be able to scan your vehicle’s onboard computer and document and decipher any trouble codes, as well as check for any manufacturer service notification codes.

Although there are many problems associated with vehicles, there are some common codes that frequently occur during diagnostic scans.
- Oxygen Sensor codes: A faulty oxygen sensor can cause your gas mileage to increase or cause your car to randomly stall.
- Engine misfire codes: Engine misfires happen if one or more of the cylinders are not working properly. If your car is vibrating or shaking during idle and your car’s fuel efficiency is not as great as it should be, you may be having an engine misfire problem,
- Evaporative system codes: The EVAP system is in charge of containing and removing vapors produced when the fuel is burned. A loose gas cap is most frequently the culprit in tripping this code.
- Exhaust gas recirculation code: The EGR controls the engine’s emission of smog-causing nitrous oxides. Problems will occur if the oil has not been changed in a while or the car is taking too many short trips and is not being allowed enough time to warm up, which can cause carbon buildup.
- Catalytic Converter codes: The downstream oxygen sensor monitors the catalytic converter. It can become contaminated and increase the tailpipe emissions if the engine is burning oil or leaking coolant internally. It can also become contaminated due to age.
Your scan tool will display any diagnostic fault codes that are present in numerical order. The technician scanning your vehicle will write down the codes and look up the definition of the code if they need it. Most codes do not tell you what part needs to be replaced, only that a problem is occurring within a certain circuit or system. Sometimes further diagnostics are needed to find the source of the problem.
