Hey...
now, I am not shorting the bus physically. I am using a CAN Stress
tool, to induce the error in the ECU transmission. After sometimes,
the ECU goes into the bus off. And the CANalyzer is in listen mode. I
am observing error frames continously on the CANalyzer trace window. I
am not sure why the error messages should come on bus. When the ECU
goes into Bus Off, I stop all the communication in the software for
1000 ms. And then reinitialize it. So as per my understanding, During
those
1000 ms I should not receive any error frames.....
am I correct ?? or soemthing else is expected ??

Does it mean, when bus is shorted there will not be any kind of frames
on the Bus?? Not even error frames ???
Yes - if the bus is physically shorted, no signal of any kind can get
through. The CANalyzer sees nothing until you remove the short.
