Other Discovery 3 2005

Hi
My rear parking sensors have stopped working recently.

If I TURN IGNITION ON (WITHOUT STARTING ENGINE) PLACE GEAR IN REVERSE AND TURN HAND BRAKE OFF THE SENSORS WORK.
WHEN I PLACE GEAR IN PARK THEN TURN ENGINE ON (ENGINE RUNNING) SELECT REVERSE THE SENSOR DOES NOT WORK.

HELP PLEASE.
