Stupid question about can

Post by W/0AKLUE »

Hello all, first time poster here. My question is fairly simple i think. Does a module on a can network broadcast? As in if i built a can network and connected a single power steering module to it and powered it would it announce its presence and transmit or idle at 2.5v until it was communicated with? Thanks in advance and i know it's not a well worded question. 2016 ford fusion se 2.0L

Depends how the module is programmed. Both options are possible. But can with one module won’t work as acknowledge bit cannot be sent.
Safety critical modules don’t rely on can as a single on off command medium.
It’s like designing a safety critical function in an airplane to rely on a single sensor input, no serious company does that.
