Having some issues with a tac20 that's about a 4hour drive 1 way.
2 stop unit
I can run on inspection fine.
If taken off inspection near the top floor it will level to top floor and will take the call to the bottom floor.
As it get to the bottom floor it levels then faults out with 1025 bp parity fault. It will not run again after this unless you take to top floor on inspection and repeat.
So far the leveling and BPP mag have been changed at the bottom floor using the template to ensure alignment and south (yellow side) facing out.
The selector has been changed and a new hoistway scan has been done and completed without error.
My next step was going to be reloading software but the thumb drive was not onsite.
Customer has alegitly found thumbdrive and im looking for any other suggestions before making the 4 hour 1 way trip to continue on

I'm using IMS
Thank you for any help
