These advanced diagnostic tools go beyond simply reading error codes; they allow you to interact with your vehicle’s systems, perform tests, and even program certain components. A broken down car is frustrating, and waiting for a mechanic can be even worse. Take control of the situation with a bi-directional scan tool from AutoZone.
Understanding Bi-Directional Scan Tools
Bi-directional scan tools, also known as scan tools with actuation or control functions, provide a two-way communication pathway between the tool and your vehicle’s onboard diagnostic system (OBD). Unlike basic code readers that only retrieve diagnostic trouble codes (DTCs), bi-directional scanners can command various vehicle systems to perform specific actions. This functionality allows for more in-depth diagnostics and troubleshooting. For example, you could use a bi-directional scan tool to activate a fuel injector, cycle an ABS pump, or control various other components. This capability allows you to pinpoint the source of a problem more efficiently than with a basic code reader.
How Bi-Directional Scan Tools Work with Your Car’s OBD System
Your car’s OBD system continuously monitors engine sensors for temperature, fuel levels, oxygen, and more. This data is fed to the engine computer, which uses it to detect malfunctions. When an issue is detected, the computer logs a DTC and illuminates the check engine light.
A bi-directional scan tool connects to the OBD port, typically located under the dashboard. It then communicates with the engine computer, allowing you to retrieve DTCs and view live data streams from various sensors. More importantly, it lets you send commands to test components and confirm diagnoses.
