GENERAL OPERATION
Type 'E' Infrared Remote Control Rolling 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 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 al-
low the fuel to the engine. This type is for diesel only vehicles and will al-
low up to four or 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 al-
low 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 that 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 integrated control unit.
