I purchased a used 2011 RAM 2500 with IBC. No matter where I set the gain, I get an IBC indication of 30 when I step on the brake. There is no difference if the brake is lightly touched or heavy.

Is this normal? What does the 30 mean?
This 30 indication is new and not what I see on other RAM trucks with IBC.

Ruled out trailer problem, because other trucks do not have issue with my trailer. My indication travels with the truck to other trailers.
