Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.working after noon till just after midnight.
Can I get all the codes stored?
There should be more than this one U code. A U code means there is a module failure or a communication wire between modules that is shorted.
Hello again Chris here,
Glad you got is resolved.
