STM32 F446ZE - Board MB1162B-02

[HKuma.1]

I 'm using this board for CAN communication with CAN1. I notice in User manual UM1871 Figure 14. MCU 1 CAN1_TX is connected via SB18 and it is open. For CAN1_RX it is mentioned in user manual that I have to close for Rx to work and not mentioned about Tx pin. Do I need to close SB18 for CAN TX to work and it is missed listed in user manual. Please respond.
