CAN transceiver reset

CAN bus latched failure status doesn't allow normal working before eather a software reflashing or a power reset. It's just unacceptable that the device crash and there is no way to reset it softwarely or even have this feature build-in in the low level firmware layers. Every other components can achive that "return to normal state" when the fault disappears. 

We tested it today by shorting can bus conductors together. We where expecting that disabling and re-enabling components would get them "back to life" for the Parker IQAN system. Finally not, the bus error stays (bus-off), other components of the system (Motors, battery and controllers) get back to normal state and keep "talking" despite IQAN MC43-FS device is still flagging "Timout" on their Can messages and "No Contact" on Can its message outputs.

It's major ! With actual safety related involvment ! 

By chance, that time it happened on a charging infrastructure so while the vehicle where immobilized, but what could we do if an error occures while the vehicle is circulating on the highway ?! It's just not acceptable to permanently lose power (by controlling a drivetrain) while the error / fault is gone. It must have a way to reset the bus !

Thanks for following-up !
