nected or wires cut it will operate for approximately 3 minutes. To disconnect

2. Disconnect Sounder within 15 seconds
3. If Triggered, Re-connect.
4. Disarm Alarm system
5. Turn Ignition on and repeat steps above.
INERTIA SWITCH
The inertia switch has been incorporated into the alarm system to activate the
central locking mechanism’s if the vehicle is involved in an accident.
ENGINE IMMOBILISER (Optional)
When the alarm system is armed, the Passive Immobilisation function is en-
abled. Two types of immobilisation are used :-
1. Electronic Engine Immobiliser (Used on MFI-T16 and 300TDi with EDC en-
gines)
This system is controlled by the Engine Management ECU and the Alarm ECU.
When the vehicle is immobilised, the alarm ECU sends a signal to the EMS ECU
which prevents starting, and until it receives a de-immobilise signal it will not
start.
2. Remote Smart Spider (Used on MFI-T16 and 300TDi without EDC engines)
This system is controlled by the alarm ECU and the Engine immobilisation ECU
(Spider).
The alarm ECU sends a signal to the spider ECU to disable vehicle start, which it
then interrupts the starter circuit, fuel pump circuit and ignition coil (If fitted) or
the fuel pump shut off solenoid in the case for the 300TDi engine (without EGR).
NOTE : The vehicle can only be started using the Plip key or the EKA code.
PASSIVE IMMOBILISER
The immobiliser system will be enabled when the following conditions apply :-
• 30 seconds after ignition is switch off and drivers door has been opened.
• 5 minutes after ignition is switched off.
• 5 minutes after disarming the alarm system.
PASSIVE IMMOBILISER COIL
A coil is mounted in the steering column which sends a magnetic field which is
picked up by the plip key, and if received, it sends a signal to the alarm ECU to
mobilise the vehicle.
