Searching for an answer to this problem there is not much that is mentioned on what resolves the issue, today I did a job where i needed to replace a faulty
ICC, and once i fitted the new unit i got the "CODE" come up on the screen, long story short, the bottom right bolt that holds the
ICC unit to the car is an earth point, and once i screwed the bolt in the "CODE" went away, just thought this info would be useful for someone in the future.
