ALARM SYSTEM AND HORN

86-4-22 DESCRIPTION AND OPERATION

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. 

Single point entry
Single point entry (SPE) allows the driver to unlock the driver's door while leaving all other doors locked.

There are two configurations for single point entry:

l

SPE not active.

l

SPE active.

To use SPE, press the unlock button on the handset once.  Depressing the unlock button a second time in the space 
of one minute unlocks the remaining doors.  SPE is also possible by turning the key in the driver's door lock to the 
unlock position once.  Turning the key to the unlock position again within one minute unlocks the remaining doors.

In order for SPE to operate, the following conditions must be met:

l

The ignition is off.

l

All doors are locked.

Speed related locking
For added protection the vehicle doors can automatically lock when the vehicle exceeds a specific road speed.

There are two configurations for speed related locking:

l

Speed related locking not active.

l

Speed related locking active.

Speed related locking causes the doors to automatically lock when the vehicle exceeds a speed of 4 mph (7 km/h).  
When the ignition is switched off, the doors are automatically unlocked.  Depressing the instrument panel mounted 
central door unlocking switch disables the speed related locking for the duration of the journey.

Speed related locking only activates once per ignition cycle.  If speed related locking activates and a door is then 
unlocked, the door does not automatically re-lock.
