Abstract
A controller area network (CAN) includes a CAN bus with a CAN-H wire, a CAN-L wire, a pair of CAN bus terminators located at opposite ends of the CAN bus, each terminator having a corresponding known terminator resistance value, a plurality of nodes including controllers wherein at least one of said controllers is a monitoring controller. The monitoring controller includes a detection control routine for detecting the presence of a wire-open fault on the CAN bus, including determining a CAN bus resistance, and determining a wire-open fault on the CAN bus based upon the determined CAN bus resistance and the terminator resistance values.
