Will CG100X Read Honda Civic 2022 S6J336x Chip?

Honda Civic 2022 (11gen)  
Most are locked MCU.
78100 - T21 - A730 - M1
Family: S6J336x
Full chip name: S6J336AHTB


Tips for all S6J chips:
If your Dflash read shows all FFFF, the chip might be encrypted.
How to confirm if the chip is encrypted? Try reading the Pflash.
If Pflash reads successfully but Dflash doesn't, the chip is encrypted.
If neither Pflash nor Dflash reads, you're having a connection issue.
*If MCU is not encrypted, CG100X reads it without problem. If encrypted, it reads all FFF.
