Description
JDiag • Automotive diagnostic tool T200
The JDiag T200 is a professional-level OBD-II diagnostic tool for automotive technicians. It supports a wide voltage input (8-30 V) and operates with a 2.4-inch color TFT screen (320×240), enabling clear display under varied lighting. Built for OBD-II compliant vehicles, it reads generic, manufacturer-specific, pending and permanent diagnostic trouble codes (DTCs), displays live sensor data, performs emissions readiness tests, and monitors battery and OBD interface voltage. It includes mode-6 and mode-8 diagnostic functions for more advanced system tests.
