In the event of an defective wire in the low-speed CAN communication of vehicle, the problem had to be solved by relying on fault codes or using expensive measuring equipment. An experiment was conducted to analyze waveforms of communication circuits with wire conditions such as normal, short circuits in the main body, and mutual short circuits. When the controller drives the CAN transceiver and transmits a message, the voltage and current waveforms were measured using an OEM oscilloscope to check for abnormalities in the circuit. As a result, it was confirmed that when a defective wire occurs in low-speed CAN communication, the CAN driver can switch to the fail-safe mode to exchange normal messages.
