Can bus without termination resistor

WebCAN bus reading 120 ohms? Tip #1: Measure the resistance. The most common CAN-Bus issue is too much or too little termination resistance. In a low speed CAN each device should have a 120 Ohm resistor. In a high speed CAN-Bus (>100Kbit, used in automotive) only each end of the main loop should have a 120 Ohm resistor. WebA CAN bus terminator can be used for termination of any high speed (ISO 11898-2) CAN bus system. The 120 Ohm terminating resistor is setup between pin 2 (CAN low) and pin 7 (CAN high). In general, ISO 11898-2 CAN networks must be terminated at each end using 120 Ohm terminal resistors.
