Stable characteristics, high reliability. 1. The MOST Diagnostic Kit helps quickly identify fault points, whether related to the motherboard transceiver or cable connection issues. 2. The optical fiber loop allows removal or addition of a single vehicle component without affecting the car's fiber-optic network. 3. It can diagnose and locate fault points at any node within the MOST (Media Oriented Systems Transport) system. 4. In cases where the Bluetooth phone module causes intermittent sound or no o when the stereo is on, disconnecting the fiber head from the phone module and connecting it to the fiber loop deactivates the Bluetooth phone function, restoring normal o immediately.
