Frequently Asked Questions (FAQs)
Q: Why does the automatic scanning fail?
A: The success of automatic scanning depends on several factors:
- Ensure the diagnostic instrument and ECU are correctly connected, and the ECU is powered before initiating automatic scanning.
- If the ECU remains powered without communication for a period (seconds or minutes), it may enter hibernation mode and become unresponsive—requiring a power cycle.
- Some ECUs do not actively transmit CAN signals; in such cases, manual configuration of the device is necessary.
- CAN FD is not supported for automatic scanning—manual setup is required.
Q: Where can I check the wiring diagram of the CAN driver?
A: Download the OBDSTAR APP from the Apple App Store or Google Play Store. The app includes wiring diagrams for Dash, Audio, Gear Lever, and more.
Q: What does the 120Ω resistor do?
A: If the ECU does not include a built-in 120Ω resistor, you must switch the unit’s resistor switch to ON to ensure proper CAN line communication.
Q: Is the FlexRay protocol supported?
A: No, it is not supported.
