Types of Car Diagnostic Tools
Car diagnostic tools come in various shapes and sizes, each with its own set of capabilities. Understanding the different types can help you choose the right tool for your needs.
Basic Code Readers
Basic code readers are entry-level tools primarily designed to retrieve DTCs. They are a cost-effective option for DIYers looking to understand basic engine problems.
OBD2 Scanners
OBD2 scanners offer more advanced functionalities than basic code readers. They can access live data streams, allowing you to monitor various sensor readings in real-time. This helps in identifying intermittent issues that might not trigger a DTC. Some popular choices include the elm327 bluetooth obd2 car diagnostic scanner tool and the bluetooth obd2 car diagnostic interface tool.
Professional Scan Tools
Professional scan tools are used by mechanics and technicians in repair shops. They provide comprehensive diagnostic capabilities, including bi-directional control, which allows you to activate certain components for testing purposes. The snap on professional car scan tool is a well-known example in the professional field.
