Clearing Range Rover ECU fault codes

As applied to a 1990 NAS Range Rover Classic:

Clearing Fault Codes
1. Switch ignition on.
2. Disconnect serial link mating plug, wait 5 seconds, then reconnect.
3. Switch ignition off, wait for main relay to drop out.
4. Switch ignition on. The display should now be reset. If there are other faults, the next one will be displayed. Otherwise the display will be black.
5. If there is more than one fault repeat steps 1 to 4, to clear each fault until the display is blank.
