Engine immobiliser
The SIM 32 computer manages an engine immobiliser program:
–The Verlog 4 type immobiliser function is managed by the UCH computer and the engine management computer.
Before any customer request, the engine management computer and UCH exchange authentication frames via the
multiplex network to determine whether or not to start the engine.
After more than five consecutive failed authentication attempts, the engine management computer goes into
protection (antiscanning) mode and no longer tries to authenticate the UCH. It only leaves this mode when the
following sequence of operations is carried out:
–the ignition is left on for at least 60 seconds,
–the signal is cut off,
–the injection computer self-supply cuts out when it should (the time varies according to engine temperature).
After this, only one authentication attempt is allowed. If this fails again, repeat the sequence of operations described
above.
If the engine management computer still fails to unlock, contact the Techline.
Impact detected
If an impacthas been stored by the injection computer (ET077 Impactdetected), switch off the ignition for10 seconds,
thenswitch it back on so that the e ngine can b e started. Then clear the faults using commandRZ0 01 Fault memory.
Fuel supply
Fuel is supplied by the fuel pump. It is controlled each time the ignition is switched on, for 1 second, to provide a
certain pressure level in the circuit, and thereby achieve correct engine starting, particularly if the vehicle has not
been used for a long time. When the engine is running, the fuel pump relay is always controlled.
Injection
The injectors are controlled according to several modes. The engine is started in "semi-full group" mode (injectors
1 and 4, then injectors 2 and 3 simultaneously). This is to ensure correct engine starting whether or not it is correctly
phased, then it enters sequential mode.
It can sometimes, though rarely, happen that the engine starts when incorrectly phased. Then, after it has changed
to sequential injection mode and as long as the cylinder 1 recognition program has not taken place, the injectors are
offset by two cylinders: injection occurs in 4-2-1-3 order instead of the expected 1-3-4-2.
Injection timing is continuously calculated. It can be zero in the event of cut-off whilst decelerating or overrevving for
example.
Engine phasing
SIM 32 D4F 764 injection systems are equipped with a delayed continuous inlet camshaft dephaser.
The injection receives the position of the camshaft dephaser given by the camshaft sensor signal.
This position does not recognise whether the camshaft dephaser is in defect mode or not.
There are two types of defect mode associated with the various types of camshaft dephaser faults:

–The Verlog 4 type immobiliser function is managed by the UCH computer and the engine management computer.
Before any customer request, the engine management computer and UCH exchange authentication frames via the
multiplex network to determine whether or not to start the engine.
After more than five consecutive failed authentication attempts, the engine management computer goes into
protection (antiscanning) mode and no longer tries to authenticate the UCH. The engine management computer only
exits this mode if the following sequence of operations is respected:
–the ignition is left on for at least 60 seconds,
–the signal is cut off,
–the injection computer self-feed deactivates when it should (the time varies according to engine coolant
temperature.
Following this sequence of operations, a single authentication attempt is authorised. If this fails again, repeat the
sequence of operations described above.
If the engine management computer still fails to unlock, contact the Techline.
Impact detected
If an impact has been stored by the injection computer (ET077 Impact detected), switch off the ignition for
10 seconds, then switch it back on so that the engine can be started. Then clear the faults using command RZ001
Fault memory.
Fuel supply
Fuel is supplied by the fuel pump. It is controlled each time the ignition is switched on, for 1 second, to provide a
certain pressure level in the circuit, and thereby achieve correct engine starting, particularly if the vehicle has not
been used for a long time. When the engine is running, the fuel pump relay is always controlled.

The injectors are controlled according to several modes. In particular, the engine is started in semi-full group mode
(injectors 1 and 4, then injectors 2 and 3 simultaneously), to ensure a correct start whether or not it is correctly
phased, then it enters sequential mode.
It can sometimes, though rarely, happen that the engine starts when incorrectly phased.
Then, after it has changed to sequential injection mode and as long as the cylinder 1 recognition program has not
taken place, the injectors are offset by two cylinders: injection occurs in the order 4-2-1-3 instead of the expected
order 1-3-4-2.

Air conditioning function
The SIM32 computer manages a "Cold Loop" type air conditioning system:
–request for air conditioning by logical link,
–acquisition of pressure in the air conditioning circuit,
–vehicle speed
–air conditioning compressor control,
–fan unit control for the requirements of this function.
The injection computer reconstitutes the power absorbed by the air conditioning compressor and fast idle speed
requests by using the pressure acquired in the air conditioning circuit.
These signals are necessary for adapting the engine management (idling speed regulation, air flow correction, etc.),
for several reasons:
–air conditioning compressor efficiency,
–more engine ruggedness due to torque hesitation caused by the compressor clutching and declutching,
–helping the alternator.
Fan unit 1 and/or 2 requests are reconstituted according to the pressure in the air conditioning circuit and the vehicle
speed. In summary, there are more fan unit requests when the speed is low and the pressure is high.
OCS - Customised Oil Change Interval (does not concern Vdiag 44 and 4C).
This program takes into account the driving style of the user to warn him of the need for an oil service. It counts the
number of revs per minute since the last oil service, corrected by a factor dependent on the oil temperature. When
this number of revs per minute exceeds a certain threshold, the customer is alerted by a message on the instrument
panel informing him that an oil service is required.
After the oil service, the user must reset the oil service interval on the instrument panel.
To find out if the engine concerned uses this programming, consult ET840 Customised Oil Change Interval.
OBD
The OBD programs are as follows:
–catalytic converter fault finding,
–upstream sensor operational fault finding,
–misfire fault finding,
–fuel supply system fault finding.
The misfiring and fuel supply system fault finding is performed continuously. The operational fault finding for the
upstream sensor and the catalytic converter can be only be carried out once per journey, and can never take place
at the same time.

PRESENT

STOREDACCELERATOR PEDAL POSITION SIGNAL
1.DEF: Signal incoherent
NOTESConditions for applying the fault finding procedure to stored faults:
If the customer complains of intermittent faults typical of defect mode type 3
(no accelerator pedal, cruise control or speed limiter), and that the ESP indicator
light comes on but the injection system displays no present faults, apply this fault
finding procedure.
Special notes:
This fault finding procedure enables an accelerator pedal mechanical seizure type fault
to be displayed whilst the pedal is depressed (when the driver's foot is lifted, the pedal
position remains the same). In this case, the driver will brake.
This program enables an inconsistency in the driver's behaviour, such as the brake
pedal and accelerator being depressed simultaneously to be detected (but enables
heel/toe points and left foot braking to be performed without displaying a fault).
There are two possible cases:
1. The fault finding procedure detects constant acceleration then braking with the
acceleration still maintained => change to reversible type 3 defect mode (see
System operation) which no longer recognises the accelerator pedal => warning
light does not come on, fault is not stored. If the accelerator pedal changes position
before the end of a time delay (approximately 31 seconds), it exits defect mode
and returns to normal mode.
2. If the accelerator pedal does not change position for the entire time delay
(approximately 31 seconds), it goes irreversibly into defect mode (requires the
ignition to be switched off to exit it). The warning light comes on and the fault is
stored. This fault finding procedure has no relation with the throttle position.
An accelerator fault (locking, for example) is needed to show the stored fault.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.

ET051THROTTLE STOP PROGRAMMING–Completed
–Not completed
STATUS
DEFINITIONDONE: This status indicates that the throttle stop programming has been completed.
NOT DONE: This status indicates that the throttle stop programming has not been
completed.
NOTESThere must be no present or stored faults.
Special notes:
When programming is in progress, the injection system prevents the engine from
starting, until the operation is completed.
Conformity check: Engine stopped and ignition on, or engine running at idle speed, and engine coolant
temperature > 80˚C.
COMPLETED
or
NOT
COMPLETEDThis status does not change according to the ignition or engine status but according
to the programming of the component.
In the event of a fault, program the throttle stops (see Configurations and
programming).
Even though this programming is automatic, take particular care when performing the first motorised throttle stop
programming operation. This can be carried out on several occasions:
–when a computer is switched on for the first time,
–at the end of computer programming (see Configurations and programming).
The air temperature should be greater than 0˚C, during programming, then, at the end of programming, switch off
the ignition and wait 30 seconds for the end of Power Latch so that the computer can store the programmed stops.

ET556DRIVER'S DEACTIVATION OF THE CRUISE CONTROL/SPEED LIMITER
STATUS
DEFINITIONSTATUS 1: This status indicates that the cruise control/speed limiter function is
deactivated each time the brake pedal is depressed.
STATUS 2: This status indicates that the cruise control/speed limiter function is
deactivated after the suspend button is pressed.
STATUS 3: This status indicates that the cruise control/speed limiter function is
deactivated after the clutch pedal is depressed.
STATUS 4: This status indicates that the deactivation of the cruise control/speed
limiter function is deactivated after the gear lever is put into neutral.
NOTESCruise control remains deactivated as long as the vehicle speed does not exceed
a speed V >18 mph (30 km/h).
IMPORTANT
Certain deactivations are stored by the computer.
To reinitialise this status, run RZ001 Fault memory.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
STATUS 1 Brake pedal depressed
If status ET556 becomes STATUS 1 if the cruise control function is deactivated when
the brake pedal is depressed.
Run fault finding on the ABS circuit (see 38C, Anti-lock braking system).
STATUS 2 Cancel button pressed
Status ET556 changes to STATUS 3 when driving, with cruise control active, if the
driver presses the cruise control/speed limiter 0 button.
If status ET556 becomes STATUS 3 without pressing cruise control/speed limiter
button 0, run fault finding on the cruise control/speed limiter control button R/0.

STATUS 3 Cruise control or speed limiter fault
If status ET557 is STATUS 3, consult the interpretation of status ET042 Cruise
control/speed limiter, to test the cruise control system components and find the
faulty component.
If status ET557 changes to STATUS 3, deal with the faults present or stored in the
computer.
If the fault is still present, contact the Techline.
STATUS 4 Invalid vehicle speed
If status ET557 changes to STATUS 4 if the vehicle speed received by the computer
is not consistent with the request.
In the event of any faults, run fault finding on the ABS computer (see 38C, Anti-lock
braking system).
If the fault is still present, contact the Techline.
STATUS 5 Traction control request
If the vehicle being diagnosed is fitted with traction control, the cruise control function
is deactivated each time traction control is selected.
Status ET557 changes to STATUS 5, when driving, with cruise control active and
traction control requested.
Status ET557 changes to STATUS 5 without a traction control request (see 38C,
Anti-lock braking system).
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
