OBDSTAR MT203 FAQs:

Q: Can the device be upgraded?
A: Yes, you can download the software from the official website "Service-Download-One Click Upgrade Tool", and then connect the device to the computer with USB to upgrade it.

Q: Why does the automatic scanning fail?
A: The success of the automatic scanning depends on a number of factors:

1. Make sure that the diagnostic instrument and ECU are connected correctly first, and the ECU is powered up before the automatic scanning is performed;
2. ECU power on for a period of time (a few seconds or minutes) did not communicate, may enter the hibernation mode, can not communicate, need to re-power on;
3. Part of the ECU will not take the initiative to send CAN signals, at this time you need to manually set the device;
4. CANFD currently doesn't support automatic scanning, please set it manually.

Q: Where to check the wiring diagram of CAN driver?

A: You can download the OBDSTAR APP from the Apple Store and Google Play Store. There are wiring diagrams for Dash, Audio, Gear Lever, etc. in the APP.

Q: What does the 120Ω resistor do?
A: If the ECU itself does not come with a 120Ω resistor, you need to switch the unit's resistor switch to ON for the CAN line to communicate properly.

Q: Is the Flexray protocol supported?
A: It is not supported.
