Hello,
We are facing a problem where TCAN was working fine, however after some time it stopped communicating.
During debugging it was found that there is no nominal voltage on CAN Line, further we tried to restart system however it didn't help.
Later on debugging we found that, we are unable to read registers of TCAN IC and there is no crystal output.
Later we just disconnected choke, which was connected on CAN lines of TCAN IC and found that TCAN is again working fine. We got that nominal voltage on CAN lines.
Can anyone please help me to understand what actually happened to crystal and TCAN IC with respect to choke. Also on connecting same choke again it is working fine as expected.
