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 re-
mote infrared transmitter contained in the plastic keyhead. The transmitted code is fixed
and when received by the control unit receiver it will generate a door open signal and si-
multaneously 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 re-
mote infrared transmitter contained in the plastic keyhead. The transmitted code is fixed
and when received by the control unit receiver it will generate a door open signal and si-
multaneously 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 re-
mote 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 engine to run. This type is for petrol only vehicles and will allow up to
seven keys to be used.

GENERAL OPERATION
Type 'E' Infrared Remote Control Rolling Code - Diesel
This system uses a combined immobiliser and central door locking control unit with a re-
mote 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 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 seven keys to be
used dependent upon the type of shielding on the Coded Solenoid Valve.
Type 'F' Key Recognition - No Infrared Remote - Diesel
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 Coded Solenoid VAlve
receives a signal to allow the engine to run. This type is for diesel only vehicles and will
allow up to four or seven keys to be used depending upon the type of shielding on the
Coded Solenoid Valve.
Type 'G' Key Recognition + IR Rolling Code - 2 ECMs - Petrol/Diesel
This system has both Infrared Remote Control and Key Recognition but have a separate
control for each function. There is no interaction between the two controllers except thst
they share common 'K' & 'L' diagnostic lines to the DLC and the Electric Door Button has
an input to both to allow the code to be entered manually. This systems appears in both
petrol and diesel vehicles and up to seven keys can be used.
Type 'H' Key Recognition + IR Rolling Code - 2 ECMs - Petrol/Diesel
Types 'H' and 'G' are exactly similar in their functionality but Type 'H' has a single inte-
grated control unit.
