Abstract
Methods and systems are provided for evaluating a CAN that includes a CAN bus and a plurality of modules configured to communicate over the CAN bus. A voltage sensor may be provided in electrical communication with the CAN bus. A number (N) of pairs of voltages may be read. Each pair may include a CAN high (CAN-H) value and a CAN low (CAN-L) value. The N pair of voltages may be processed through a comparison of the CAN-H values and the CAN-L values. Whether a fault signature is present in the CAN-H and CAN-L values may be determined from the processing.
