Can bus short to ground

WebAug 29, 2024 · 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. Measure with a multi-meter the resistance … WebThe waveform below shows both the signal when CAN High and CAN Low are tested with respect to ground and the differential voltage between CAN High and Can Low. …
