WebMay 6, 2024 · The CAN bus should be terminated at each end with a 120 Ohm resistor. This is placed across the two lines CAN-H and CAH-L. Two parallel 120 ohm resistors will give you 60 ohms which is what you should be reading anywhere on that bus. You did not specify the vehicle, some have a seperate CAN bus for the OBDII connector.
