6. CAN-Bus Troubleshooting Guide

The CAN-Bus Troubleshooting Guide is a guide to find and eliminate the most frequent hardware-error
causes in the wiring of CAN-networks.

Figure. 17: Simplified diagram of a CAN network

6.1 Termination

The termination is used to match impedance of a node to the impedance of the transmission line being
used. When impedance is mismatched, the transmitted signal is not completely absorbed by the load
and a portion is reflected back into the transmission line. If the source, transmission line and load
impedance are equal these reflections are eliminated. This test measures the series resistance of the
CAN data pair conductors and the attached terminating resistors.

To test it, please

1. Turn off all power supplies of the attached CAN nodes.
2. Measure the DC resistance between CAN_H and CAN_L at the ends of the network
(see figure above) and the middle (if the network cable consists of more than one line
section).

The measured value should be between 50

and 70

. The measured value should be nearly the same

at each point of the network.

If the value is below 50

, please make sure that:

- there is no short circuit between CAN_H and CAN_L wiring
- there are not more than two terminating resistors connected
- the nodes do not have faulty transceivers.

If the value is higher than 70

, please make sure that:

- there are no open circuits in CAN_H or CAN_L wiring
- your bus system has two terminating resistors (one at each end) and that they are 120

each.
