SCBC light after firmware update

[17CX5MD]

2017 CX5 touring, A while back, I updated my software to the newest version, 74.00.324. Since then, I've had a SCBS and a parking brake fault light on. I've replaced the battery and the brake switch, and the lights are still on. If I scan codes, I get u0323 Software Incompatibility With Instrument Panel Control Module. Everything functions normally including the auto hold, but I cannot get the lights to go out. Anyone have this issue or something similar? About to just pop open the gauge cluster and tape over the lights as a last ditch.

I would send a private message to @Candurin. He might have a fix for you.

Thread 'Mazda TPMS - Brake fault after replacing battery...Help!'

Nov 6, 2022

Seems this has been a pretty common problem, but no one seems to have a good solution other than very expensive fixes by bringing to a Mazda dealer. After replacing the battery in a 2016 CX-5, the e-brake fault light and TMPS fault lights are on. Never a problem before replacing the battery and all systems seem to be working without issue, just the lights remain on. I've seen posts about this in multiple Mazdas, different models and years, but still not a post with a solution that works. I've seen the other posts in the community, but some of the solutions seem very extreme, like...

The only issue is that this is likely a PCM issue and not anything a CMU update would address. Additionally, they are already on the latest FW.

I did mention that in my DM response, it wanted to share here in case anyone else experiences the same.
