OBDstar MT203 CAN Driver / Gateway Simulator

The OBDSTAR MT203 is a CAN driver and gateway simulator designed primarily for automotive electronics maintenance, testing, and bench-level ECU repair. It’s used to simulate communication on vehicle CAN networks and replicate gateway functionality for modules that normally require a full vehicle harness or specific gateway modules to communicate with diagnostic tools.

 Key Functions & Features

🔹 CAN Drive Function

• Simulates CAN communication to “wake up” or activate modules such as dashboard, audio, gear lever, handbrake, AC panel, etc., during bench testing.

• This is useful when a control unit is detached from the vehicle network and won’t enter an operational state on its own.

 Gateway Simulation

• Many modern vehicles use gateway modules to manage communications between ECUs and diagnostic tools.
