Answer
The code you refer to is from the engine computer, which has nothing to do with the SLABS system - the source of the three lights.

Find a dealer or a Land Rover specialist with the T4 or Autologic system, and have them test the SLABS system and tell you what's wrong.

The OBD II scanner you used to get the engine code will not be helpful in this situation.
