Read and clear this fault code yourself with the EAS Unlock V4 for the P38 Range Rover.
Target Heights Incorrect
When re-calibrating the EAS heights, the EAS computer has its own set of internal limits. If those internal calibration target heights are exceeded, then the EAS computer will throw this fault code. Try the re-calibration again, but this time lessen the ammount of change you are putting in the new target height values.
