Thread: Discovery my Discoveries Immobiliser

Hoi Folks,

I've just landed a nice 1999 Discovery 2 with a v8 engine off a young lad, knowing full well it needs a little work - however the immobiliser issue has me beat so far and I NEED some help!

I'll lay out the issue as such:
It was initially something different (I suppose I'll elaborate if the remedy to this situation has no effect on the original issue), however as of yesterday, the car often won't crank. The lack of cranking is accompanied by the hazard lights self flashing for approx 20 clicks and then a rest period of approx 10 seconds.
This process carries on until either the car is locked or started.
And that's the thing, if you sit there and try, it will eventually just start.

I have disabled the horn
I have also pressed the Inertia switch, to cite no improvement.

What would you suggest, Aussie Rovers?

Hey TrunkMonk

When you did the EKA code did you follow this procedure to the letter?
As this should turn the immobiliser off??
You’ll need to reconnect the horn

Do you have access to a Nanocom?

EKA CODE INSTRUCTIONS


1 - Using the key, turn the driver's door lock to the UNLOCK position and hold in this position for at least 5 seconds.

An audible warning is then emitted to indicate that the body control unit is ready to accept the code. Return the key to the centre position. It is now possible to use the key to enter the separate numerical values of the four digits that make up the EKA code.

2 - Enter the first digit of the code. If the first digit is 4, turn the key to the UNLOCK position 4 times. Ensure the key is fully returned to the centre position after each turn of the key.

3 - Enter the second digit of the code. If the second digit is 3, turn the key to the LOCK position 3 times. Ensure the key is fully returned to the centre position after each turn of the key.

4 - Enter the third digit of the code. If the third digit is 2, turn the key to the UNLOCK position twice. Ensure the key is fully returned to the centre position after each turn of the key.

5 - Enter the fourth digit of the code. If the fourth digit is 1, turn the key to the LOCK position once. Ensure the key is fully returned to the centre position after each turn of the key.

6 - Finally, turn the key to the UNLOCK position and back to the centre position, a double bleep will indicate that the code has been entered correctly. A single bleep indicates that the code has been entered incorrectly.

Then, before opening the door, wait 5 minutes for the alarm and immobiliser to be de-activated. During the 5 minute wait for the alarm and immobiliser to be de-activated, the alarm indicator LED in the instrument pack continues to flash (one flash every 2 seconds).
DO NOT OPEN THE DOOR OR ATTEMPT TO ENTER THE CAR until the full delay period has elapsed.

When the 5 minute wait has elapsed, the alarm indicator LED stops flashing. Immediately open the door, insert the key in the ignition switch and turn the switch to position II. If the ignition switch is not turned to position II within 30 seconds of the end of the 5 minute wait, the engine is automatically immobilised again.

The EKA code will not be recognised if there is an interval of 10 seconds or more between key turns or if the key is held turned for 5 seconds or more during the procedure.

In some system configurations a successful EKA code entry is indicated by the audible warning device pulsing twice for a period of 50 ms on, 200 ms off. The theft deterrent LED is switched on for 1 second, all doors emobilised allowing the engine to start.

If an incorrect code is entered, an audible warning is emitted and the procedure must be repeated. Up to a maximum of 10 attempts to enter the code is possible. After 10 attempts, the BCU will not allow any further codes to be entered for a period of 10 minutes.
