Code requirement and bypass switch are "0" and one of the bypass inputs is high
The Down leveling valve driver was on when it was not commanded on by software OR the down level valve driver was commanded on by software and no ooutput was seen at the DL output (Area 7).

You might have to replace your main IO board. Sometimes the hoistway and car door bypass switches go bad and it’ll give you this fault.
