TDA4VH-Q1: TDA4VH-Q1: Validation of CAN3 and CAN5 doesn't work

Part Number: TDA4VH-Q1

Tool/software:

Hi.

I'm using TDA4VH-Q1 evm board. I'm trying to control MCAN3 or MCAN5 using MCU2_1 which is R5F. 
I changed pinmux just like below and checked the MCAN3_H, MCAN_L pin is up to 2.5V.

However, I couldn't receive any can message from it. Please help me if there with this.
