GENERAL OPERATION
All systems have the same end function, immobilizing the vehicle until the
correct code is presented to the immobiliser unit.
Type 'A' Infrared Remote Control Fixed Code - Petrol
This system uses a combined immobiliser and central door locking control
unit with a remote infrared transmitter contained in the plastic keyhead.
The transmitted code is fixed and when received by the control unit re-
ceiver it will generate a door open signal and simultaneously pass the
code to the EMS-ECM. The EMS-ECM compares the received code against
a stored code and if verified it will allow the engine to be started. This
type is for petrol only vehicles and will allow up to seven keys to be used.
Type 'B' Infrared Remote Control Fixed Code - Diesel
This system uses a combined immobiliser and central door locking control
unit with a remote infrared transmitter contained in the plastic keyhead.
The transmitted code is fixed and when received by the control unit re-
ceiver it will generate a door open signal and simultaneously pass the
code to the Coded Solenoid Valve. The Coded Solenoid Valve compares
the received code against a stored code and if verified it will allow the fuel
to the engine. This type is for diesel only vehicles and will allow up to four
keys to be used.
Type 'C' Infrared Remote Control Rolling Code - Petrol
This system uses a combined immobiliser and central door locking control
unit with a remote infrared transmitter contained in the plastic keyhead.
The transmitted code is rolling to reduce the chances of the code being
captured and used to enter the vehicle. The code when received by the
control unit receiver it will generate a door open signal and simultaneously
pass the code to the EMS-ECM. The EMS-ECM compares the received code
against a stored code and if verified it will allow the fuel to the engine.
This type is for petrol only vehicles and will allow up to seven keys to be
used.
Type 'D' Key Recognition - No Infrared Remote - Petrol
This system uses key recognition only with no remote control of entry. A
transponder in the keyhead reacts to a transmitted signal from a coil
wrapped around the ignition key barrel. If the transponder code is the
same as the stored code the EMS-ECM receives a signal to allow the en-
gine to run. This type is for petrol only vehicles and will allow up to seven
keys to be used.
