Can TJA1043 detect short circuit to battery voltage with CANH, CANL and change ERR PIN

TJA1055 (Low Speed Fault Tolerant CAN Transceiver) can detect short-circuit to battery voltage on pin CANH and CANL respectively in normal and low power mode. In the datasheet, however, TJA1043 seems to detect short-circuit by monitoring the differential voltage of CANH and CANL. Is that right? or is TJA1043 also capable of detecting short-circuit of each CANL and CANL seperatively?

 

And one more question is that what is the voltage of CANL and CANH in normal mode and sleep mode?
