Serious help with alfaobd

[joemo]

*** Solved and solution is in post #9 *** Special thanks to Daverous for his fix over 2 years ago.

Hoping someone can help me on this one. I spent over 5 hours tonight in alfaobd trying to fix the issue. This all started with a simple tire size change. Next thing I know I had errors everywhere. Parking sensors were not working etc. I learned a ton about alfaobd but I am stuck on one issue yet. I am getting the parking brake error C10D0

I know there is nothing wrong hardware wise. The brake works just fine. No error was on until I started meddling like the kids from Scooby Doo. I do not have a backup, which is one major lesson I learned from this.

When I go into ABS, I can read the error and clear it but it comes right back again. Hoping someone from here will give me some insight.

I have a 2020 Big Horn.

Thanks

What size did you adjust your tire to?

What size did you adjust your tire to?

I adjusted based on mm but then reverted back to the original size I had before I started all this.

If you go over 2710, things get funky.
Did you put the original number back in and let the truck sleep for 10 mins?

I just went out to take a look after like 25 and its still the same error and clearing it brings it right back. I will have to check tomorrow morning. Thanks

You saved your raw BCM file before making any changes right?

I mentioned in the 1st post I did not back up. Lesson learned.

I followed another guide but I do can't seem to find this option:
BCM> MY2020>Chassis- Electonic Parking Brake> Yes

And solved!
Sometimes a night of sleep is all you need.
I found another thread yesterday with the same issue but his solution didn’t "seem" to work for me.

ABS>DT 2019+> ECS In Plant Mode> Disable
ABS>DT 2019+ > EPB In Plant Mode> Disable
BCM> MY2020>Chassis- Electonic Parking Brake> Yes
ABS > DT 2019> Service Procedures > Assembly Check *** this was the one that I did not due to an error. This needs to be run with the parking brake DISENGAGED.

Once I disengaged the parking brake and ran the assembly check, error is gone.

I did make a backup now of my BCM.
