Extended Profile

      This position is achieved when vehicle is off road in standard or high profile and the chassis is grounded, leaving wheels unsupported.  Initial ECU reaction is to deflate (lower) affected springs.  After a timed period ECU detects no height change, therefore it re-inflates springs in an attempt to regain traction.  The RAISE lamp will flash in this mode.  After ten minutes the system will return to high profile, unless LOWER switch is pressed.
