Hi@LincoIn
I tested the configuration file in your appendix,and I think there is no problem with this configuration.
and this test using S32K142EVB(because S32K148EVB does not use UJA1169).
When I press the SW3 button, the SBC enters sleep mode. When I send a frame with an ID of 0x1A0, the SBC can be awakened and the received content will be forwarded at the same time.
Only 0x1A0 can wake up SBC,other like 0x1A2 can not wake up SBC.

So I guess this is not a configuration problem,please check your hardware or other.
and one more thing to confirm.

only UJA1169TK/F,UJA1169TKX/F,UJA1169TK/F/3 supported CAN partial networking according to the Datasheet.
BR!
Jim,
