WebDec 2, 2024 · There are various ways that the CAN bus fails. The most common failures are poor connections, opens, short to power, and short to ground. A module could also fail and bring down the whole CAN bus by shorting it to ground or power. If you’ve lost communication to only one module, it could be the module, a poor connection, wiring … WebMay 30, 2024 · CAN bus short to ground? Shorts and opens: The CAN controllers will tolerate a short circuit of one of the two lines to ground because of the characteristics of the differential bus. It cannot tol- erate both CAN bus wires shorted to ground or to each other. It will tolerate one of the CAN lines being open or disconnected.

WebAug 11, 2024 · Hence the capacitor C1: Provides the shortest path from digital ground to earth at very high frequencies (i.e. noise) by its nature. C1 is open at low frequencies or DC, but you want a path from your digital ground to the earth. Hence the resistor R3. 1M/1n pair is widely used for that purpose (e.g. ethernet chassis to earth).

These known good waveforms have the following characteristics: The CAN-L and CAN-H waveforms mirror each other about 2.5 V and have a 1 V peak to peak amplitude. The CAN-L waveform switches from 2.5 V down to 1.5 V and the CAN-H waveform switches from 2.5 V up to 3.5 V.
