Like my SatNav which tells me my average moving speed was only 34mph.
OBD readers and SatNavs are great gadgets but I don't trust some of the average statistics they can show.
The EKA relates to a DIY means of resetting the immobiliser/security low level issues to enable the car to a driveable mode.
The four digit code is translated into a specific number of turns with the key in the drivers door lock, clockwise & anti clockwise (Lock & Unlock positions)...e.g a code of say 1234 would signify 1 turn to lock, 2 turns to unlock, 3 turns to lock and 4 turns to unlock.
As the Freelander uses a different CCU to say, the P38, which has the EKA function & codes and has a Becm it is more than likely that the EKA is not a requirement on the Freelander.
Zero is not used in EKA codes due to the fact that zero turns of the key is not possible..likewise alpha characters (A-Z) are not used.
EKA codes can be changed in the Body ECU to suit user preferences and I have done this many times for P38 owners who have either lost the code or wished to change to a memorable number. I had one owner who had the original code of 9847 which was a pain in the ass..especially when it was p***ng rain-I changed it to 1212 !!!
