During the process of repairing automotive electrical modules, it is common to encounter situations where the communication line voltage is normal, but communication is not possible. The conventional solution requires using a CAN analyzer connected to PC software to check for communication data, which demands a certain level of technical expertise from the user. The WOYO CAN LIN PWM Tester is a digital tester specifically designed for automotive electronics. It is compact, easy to use, and meets the needs for rapid testing applications. The tester can detect the communication status of CAN and LIN lines both online and offline, displaying data, ID, and baud rate. Features:1.Automatic CAN-High and CAN-Low Identification; 2.Automatic Baud Rate Detection:CAN Baud Rates: 50, 83, 100, 125, 150, 200, 250, 300, 400, 500, 666, 800, 1000 kbpsLIN Baud Rates: 2400, 4800, 9600, 14400, 19200 bps 3.Voltage Measurement Function:Capable of measuring voltages below 20V, indicating whether the signal is a pulse or a constant voltage. 4.Equipped with Remote Indicator:Adapts to more repair scenarios, making it convenient to monitor CAN/LIN signal status remotely. The WOYO CAN LIN Tester provides a reliable and efficient solution for diagnosing communication issues in automotive electronic systems without requiring extensive technical knowledge, making it an ideal tool for both professional and DIY mechanics. 5.
