i cannot start my rover due to the alarm not allowing it to start.light flashes on dash,and it will not start.can it be bypassed,cut a wire,some simple solution.i dont even want this alarm.

 

It is not so simple to defeat immobilization, but it can be done.
The security system is designed to protect all the gold that Land Rover owners must transport to the dealership. There are many parts to the system and there is no single wire to easily access and snip. A skilled auto electrician could disable the alarm "spider" with full knowledge of the system and drawings from the RAVE manuals.

Normally you can reset the system with an emergency key access code, which should be recorded in your owners documents somewhere. Or you will be in for a trip by wrecker to the dealership, where you will be relieved of several Ben Franklins. The dealer may be able to program the system for lower levels of security.

Here is some info on the system from the RAVE service manual download:

Passive immobilisation

Passive immobilisation prevents the vehicle from being started unless the authorised key is used to start the vehicle.
There are only two configurations for passive immobilisation:

l

l

l

l

l

Passive remobilisation

Whenever the vehicle is immobilised, passive remobilisation of the engine occurs when the ignition is switched on,
allowing the vehicle to be started.
There are three configurations for passive remobilisation:

l

l

l

Emergency key access

If the handset fails to operate, the engine can be remobilised by using the key to enter a unique four digit Emergency
Key Access (EKA) code.
There are three configurations for emergency key access:

l

l

l EKA with super locking on receiving good passive remobilisation exciter coil signal.

The code is recorded on the security information card and is entered as follows:

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 unlock, the alarm
disarms and the vehicle is remobilised 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.

If the above procedures can't get you or your mechanic in the right direction, this is probably a dealer item for you. While you are spending the time and money for this, get a brand new battery. Weak battery can trigger alarm, so can loose or corroded terminals.

 

I think you're confusing this with the alarm from the D1. The "spider" is a D1 thing, not a D2.

If you find someone who is successful at permanently disabling the D2 alarm, please let us all know because from everything I've read about it, the level of integration between the alarm ECU, and the BCU/ECU make removing or permanently disabling the D2 alarm virtually impossible...

 

Thanks Savannah, your Emergency key access worked for me on my 99 discovery 2!
