Hello Subhash, Thank you for providing these screenshots. Based on this information, it seems that the MCU is correctly configured to provide the correct CAN TX signal, but there appears to be an issue with the CAN Transceiver implementation since this isn't being reflected on the CAN_H/CAN_L terminals. Can you provide schematic of the TCAN1043A configuration? After quickly reviewing the associated Datasheet I have the following questions: 1) Can you confirm the state of the nFault pin during this operation? 2) Do you have the WAKE pin pulled permanently high or low to prevent unwanted LWU request? 3) What is config for EN and nSTB pins? Best Regards, Zackary Fleenor
