Product Description

Full OBD2 Functionality
The TOPDON ArtiDiag900 Lite is capable of accessing and utilizing all standardized functions provided by the OBD2 system, as well as scanner/software features including certain manufacturer‑extended capabilities:
Read DTCs – Retrieve diagnostic trouble codes stored in the vehicle’s ECU.
Clear DTCs – Clear stored fault codes from the ECU after repair and turn off the malfunction indicator light.
Real‑time Data Stream – Read live data from vehicle sensors and the ECU, typically displayed in numerical or graphical form.
Readiness Status Test – Check vehicle readiness before annual inspections, especially for emission tests.
Freeze Frame Data – Read and display freeze frame data.
On‑Board Monitor Test Results – Access more detailed non‑continuous monitor test results.
Actuator Test – Active control of actuators for functional verification.

Full System Diagnostics
TOPDON ArtiDiag900 Lite communicates via the vehicle's standard diagnostic interface with all onboard electronic control units, reading their status information, fault codes, and data streams while performing functional tests. This enables a comprehensive health check of the vehicle's entire electronic/electrical architecture, accurately locating any electronically controlled faults—no matter which subsystem they occur in.
Access All Modules, No Blind Spots – Reaches every electronic control unit in the vehicle.
Reads Both Generic and Manufacturer-Specific Codes – Retrieves not only universal OBD2 codes but also detailed, manufacturer‑specific fault codes with enhanced precision.


Active Test (Bidirectional Control)
TOPDON ArtiDiag900Lite isn't just a code reader. Its Active Test (Bidirectional Control) capability allows you to take command. Send direct instructions to the vehicle's ECU to cycle actuators (like fuel injectors, relays, or window motors) or simulate sensor signals—all while the vehicle is parked. This lets you verify component functionality on the spot, turning guesswork into precise diagnosis.
Mastering Active Test is a game-changer. It drastically cuts down diagnostic time and eliminates unnecessary “swap-and-pray” part replacement, making it one of the most valuable skills for today's professional technician.
