The Standard OBDII Scan Codes.

 
The OBDii Scanner I have tried isOBD-2 and it is fine

Special *Codes* are used to identify the 4 Oxygen Sensors

A= Bank A of the engine.  Cylinder #1 is located on Engine Bank A
B= Bank B of the engine.
U= Upstream of the Catalytic Converter
D= Downstream of the Catalytic Converter

Example:
A D = Oxygen Sensor Engine Bank A, Downstream of the Catalytic Converter

Special Codes


As well as the standard codes each manufacturer has their own specific codes, and a unique header code/name from the ISO.
Rover specific header code names are 502 - 511
I don't have any information about usage on vehicles
Relevant codes could be
Rover     502 - 511
Lucas     850 - 860 CBS/ABS
          862 - 863 Diesal fuel engine control
          877       ditto
          939       ditto
Wabco     121 - 125 Breaking systems
SAGEM ?   795 - 799 Engine management
  ?GEMS?  837       Chassis
          880       On board electronics

There are 4 and 5 digit codes but none seem relevant to LR

Landrover specific diagnostic codes.

This list is the best I can find so far.
So don't bet your granney on it.
It duplicates the P1*** manufacturer codes 
from the table above.  The table is a 
subset of the SAE standard published in 
HS-3000 "On-Board Diagnostics for Light and
Medium Duty Vehicles Standards Manual".  See 
also ISO 9141 & 9141-2.
USING it may well be harmful to your vehicle!
so don't blame me when it all goes horribly wrong.
