Abstract
A controller area network (CAN) includes a CAN bus having a CAN-H wire, a CAN-L wire, and a pair of CAN bus terminators located at opposite ends of the CAN bus. The CAN further includes a plurality of nodes including controllers wherein at least one of the controllers is a monitoring controller. The monitoring controller includes a detection control routine for isolating faults on the CAN bus including measuring a CAN-H wire voltage, measuring a CAN-L wire voltage, and isolating a short fault based upon the CAN-H wire voltage and the CAN-L wire voltage.
