In standby mode of TJA1042, CAN BUS line is biased to 0V.
Hi,
this is known and expected behavior. The datasheet explicitly says that the bus is biased to GND in standby mode to minimize current consumption:
The application hints AH1014 then also describes how to deal with this situation using SPLIT pin. Of course, this needs to be handled by nodes which are not in standby mode:

Hi
Thank you for your reply.
Voltage drop occurs in standby mode, and it is necessary to use standby mode due to current consumption.
Also, there is no SPLT pin because TJA1042T / 3 is currently used.
Is it possible to pull up to the CAN bus line with a resistor like 100K?
