Try a 'hard reset'. Disconnect both battery cables from the battery, hold the positive and negative cables together for 10 seconds to do a complete discharge of all circuits, wait 10 minutes and then reconnect the battery.
From memory of when I had a Freelander, there are some cables/connectors either under the passenger carpet or just above where the passengers feet go that can be easily disconnected by a heavy footed clumsy passenger. Might be with having a look in that area if the hard rest doesn’t cure it.
