Hi everyone, I am not a native speaker of English and have no idea what exactly these two descriptions mean. They are indicated in the list of parameters for the control module ABS. I think they appear in the course of diagnosis of any Dodge vehicle tested, but the one I have is a Durango. Can anyone help me clarify what "rolls" are in this context?I would appreciate your help a lot.
