A question before ordering?An MFT Dev engineer checks the right configuration for your vehicles with you.
Ask an engineerThe OBDSTAR MT203 is a CAN and gateway simulator for bench work. It wakes up a dashboard, head unit, gear selector or climate control panel outside the vehicle, and it replaces the gateway so your diagnostic tool can talk to an ECU sitting on the workbench: airbag, dashboard, BCM, electric compressor, DC-DC converter, on-board charger. It works on its own, with any diagnostic tool.
- 3buses: standard CAN, fault-tolerant low-speed CAN, CAN FD
- Standalonebuilt-in screen and keypad, no tablet needed
- 120 Ωbuilt-in termination resistor, with switch
- Freeupdates via PC, no subscription
