CAN communication busses have become increasingly common in both OE and aftermarket applications, and particularly in the world of aftermarket standalone ECUs, we’re seeing more and more devices which communicate via CAN. This communication will require a properly designed CAN bus though if you want trouble free operation. In particular one of the common failing points is a CAN bus that either doesn’t have any terminating resistors, or one that has been fitted with multiple terminating resistors in the wrong locations. In this webinar we’ll find out what a terminating resistor is, how the CAN bus should be constructed, and see how to add terminating resistors where necessary.
