Engine immobiliser
The immobiliser function is divided between three coded computers (the UCH, the injection computer and the key).
The key and the UCH are linked by a magnetic field which is created by the transponder ring.
When the + After ignition is switched on, the key sends its identifier to the UCH via the transponder ring, located on
the ignition switch. The UCH runs through an authentication procedure with the key via the transponder ring. If the
key is allocated to the vehicle, then operation of the starter motor is authorised and the injection system is unlocked.
The injection computer has no reference code in its memory: the code which is transmitted is stored.
If the key code and the UCH code do not match, the system remains locked. The red engine immobiliser warning
light flashes (quickly). The vehicle cannot be started.
If the anti-theft tracking unit is fitted to the vehicle and the does vehicle not start, the customer should be asked the
following questions. This is to ensure that the information given by their access supplier via GSM conform with what
is noted in the computer:
– Who is your vehicle detection service supplier?
– Which activation option did you choose? (with locating system/without locating system)
– Did you request remote blocking? (If yes, this is why the engine does not start).
If the vehicle detection service cannot be activated, ask the owner:
– What is the server name of the vehicle detection service supplier?
– What is the APN address of the vehicle detection service supplier?
This is to ensure that the information given by their access supplier via GSM conform with what is noted in the
computer.
Recognition of keys in normal operationIMPORTANT
When the vehicle battery has a low charge, the drop in voltage caused by operating the starter could reactivate the
immobiliser. If the voltage is too low, the engine cannot be started, even by pushing the vehicle.

Starting
The UCH controls the command and supply part of the start-up function and the starting and charging process is
controlled by the UCH. For this function to operate normally, the protection function must have been successfully
completed.
*Powerlatch: Time required for injection computer supply after + 12V after ignition cut-off to the ignition switch. IMPORTANT:
When the vehicle battery has a low charge, the drop in voltage caused by operating the starter could reactivate the
immobiliser. If the voltage is too low, the engine cannot be started, even by pushing the vehicle.
Note:
If several, i.e. three or four, attempts have been made using a key not allocated to the vehicle, the injection
computer locks. Insert a key allocated to the vehicle for 20 seconds in + after ignition feed, then switch off the
ignition and wait for the end of power-latch* (20 minutes) to allow the injection computer to unlock.
