An OBD2 Code Reader is typically a basic device that reads and clears generic engine fault codes (DTCs) and checks emissions readiness (I/M). A Diagnostic Scan Tool is more advanced, often offering full system access (ABS, Airbag, Transmission), live data streaming, specialized reset functions (oil, EPB), and sometimes bidirectional control.
For basic troubleshooting and clearing the Check Engine Light, no. However, if you perform advanced repairs, component testing (like injector testing or cycling the ABS pump), or require complex resets and programming, a bidirectional scan tool is necessary as it allows the tool to send commands to the vehicle's systems.
While the majority of the featured products are automotive OBD2 scanners, the category of 'Diagnostic Test Measurement Tools' also includes specialized devices like drug test cups (Identify Diagnostics) and rapid health tests (BinaxNOW), which are used for diagnostic measurement in different fields.
I/M (Inspection/Maintenance) Readiness refers to whether the vehicle’s emission control systems have completed their self-tests. If all monitors are 'Ready,' the vehicle is prepared for an emissions test. This feature is crucial for states that require annual smog checks.
Investing in a high-quality diagnostic test measurement tool is the smartest way to save time and money on vehicle maintenance. Whether you choose a simple, reliable code reader like the ANCEL AD310 or a professional-grade bidirectional scanner like the TOPDON ArtiDiag900 Lite, having the ability to accurately measure and diagnose issues puts control back in your hands.
