WebThis handy sheet shows steps to test the bus with multimeter: termination resistance, CAN HIGH & LOW voltages levels and Node transceiver test. Check it out! Summary of the … 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.
WebResistance is the opposition or hindrance to the flow of electrons in a circuit. Connectors, switches, and wires all offer some resistance. For example, twisted pair wire typically contains 120 ohms of impedance, and the CAN bus has a 120-ohm resistor at each end. These resistors are often located inside two control modules to normalize voltage ...
