3. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any material damage or personal injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– use the proper tools.
Procedure for disconnecting the battery:
– switch off the ignition,
– switch off all electrical consumers,
– Wait at least 1 minute for the electronic systems to switch off,
– disconnect the battery, starting with the negative terminal.

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.

Vdiag No.: 0F
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.

KEY ALLOCATION PROCEDURE
Establish dialogue with the UCH computer.
In the menu Special commands, validate the command SC015 Key allocation.
The tool displays Remove the key from the ignition switch.
The tool displays Please enter the After-Sales code.
With the ignition switched off, enter the secret After-Sales code and confirm it by pressing ENTER.
The tool displays Warning, keys not inserted will no longer be operational. Restart the procedure to
reallocate them: programming is in progress.
The tool displays Insert the key in the ignition switch and turn on the ignition, then press Enter: switch on
the ignition with a key from the vehicle or a blank key.
The screen displays 1 key programmed, then press Enter, then remove the key from the ignition switch.
The tool asks: Would you like to program another key?
To allocate the additional keys, switch on the ignition for a few seconds with the other vehicle keys to be
programmed (three maximum), then confirm.
The screen displays 2, 3 or 4 keys programmed then remove the key from the anti-theft contactor.
This message also appears where dialogue with the UCH is lost or the battery power supply fails.WARNING:
If none of the keys is available, it will be necessary to carry out a reallocation procedure for all keys.
IMPORTANT:
These must be old keys belonging to the vehicle or new, uncoded keys
The tool displays Writing data to memory, the UCH is coded and the keys are programmed.
Several seconds will elapse before this message appears, in order to exit the reallocation mode.
IMPORTANT:
The maximum delay between operations is 5 minutes, otherwise the procedure is cancelled. The tool then
displays the message Procedure interrupted: warning, the keys assigned to the vehicle are the same as
those assigned before the procedure was started. The keys submitted before interruption of the procedure
are no longer blank and can only be assigned to this vehicle.

Check the battery voltage with the starter motor activated and the + starter supply.
Check the condition of the starter exciter terminal. Repair if necessary.
Check for +12V at the starter excitation terminal, when the starter is activated.
Repair if necessary (ignition switch supply, correct operation of the ignition switch and ignition switch/starter
connection).
If the fault is still not resolved, check that the starter motor is operating correctly. Replace the starter motor if
necessary (see MR 374, Mechanical, 16A, Starting - Charging, Starter: Removal - Refitting).
