My suspension goes up and down as selected, however, while driving occasionally I get a suspension fault error. It may or may not go out dduring that driving session, but once the engine is shut off and then turned back on the suspension fault error will not be illuminated. Any thoughts guys

 

Need codes.

But in my experience, this is a sign of two things. Either the compressor is weak and it can not fill the reservoir as needed - this can happen when driving. But typically this means it needs a reason to run and if you are not messing with the height it can mean a leak, often at a strut. So the compressor runs to keep the strut aired up but depending on heat/frequency of compressor run time it fails to keep up. If you are lucky, it is just a strut leak and the compressor is fine. That code will be singular, "too many transitions". Annoying LR decided that even though the truck knows EXACTLY which strut is leaking, the code will not say. At least I have not found anything. I think the only way to know for sure is to watch the valve blocks in live view on a GAP tool and see which one seems to operate a lot.

 

Thanks Dakota Traveler for your reply is was helpful.
