Not automatically. Conventional high-speed CAN networks commonly use 120-ohm termination at the two physical ends of the main bus. Since the Speedwire Systems hub includes a built-in terminating resistor, check the complete network design before adding another resistor. Too much termination can cause problems.

62. Where should CAN bus terminating resistors be installed?

For a conventional high-speed CAN network, termination is generally placed at the two physical ends of the main bus. The exact arrangement depends on the network topology and equipment. Follow the hub and connected-device documentation.

63. How many terminating resistors should a CAN bus network have?

A typical high-speed CAN bus uses two terminating resistors, usually 120 ohms each, at opposite ends of the main bus. The final arrangement must account for any built-in termination in the connected devices or hub.

64. Can incorrect CAN bus termination prevent an ECU from communicating?

Yes. Missing, excessive, or incorrectly located termination can degrade the signal and cause communication faults. Check the complete network rather than assuming the problem is the ECU itself.

65. How do I test CAN bus termination with a multimeter?

With the system powered off and the network in a suitable isolated state, measure resistance between CAN High and CAN Low according to the equipment manufacturer’s procedure. A conventional network with two 120-ohm terminators in parallel often measures approximately 60 ohms. Built-in termination and connected circuitry can change the reading, so interpret the result using the actual network diagram.

66. What resistance should I expect across CAN High and CAN Low when the network is powered off?

For a conventional high-speed CAN network with two 120-ohm terminating resistors connected in parallel, approximately 60 ohms is a common reading. Other configurations can produce different results. Confirm that the system is safely powered down and consult the manufacturer’s diagnostic procedure before testing.

67. Can too many terminating resistors cause CAN bus problems?

Yes. Additional termination can reduce the effective resistance of the network and place excessive electrical load on the CAN transceivers. Only install termination required by the designed network.

68. How do I troubleshoot intermittent CAN communication in a race car?

Inspect connectors and wiring, check power and ground stability, verify termination and network topology, and review communication error logs. Look for faults that occur with vibration, temperature changes, or electrical loads. If the problem persists, test individual network sections using the manufacturer’s diagnostic guidance.
