Engine immobiliser
This Verlog 2 type immobiliser function is managed by the UCH computer and the injection computer.
Before any starting request, the injection computer is protected.
When a starting request is made, the injection computer and the Passenger Compartment Control Unit (UCH)
exchange authentication data via the multiplex network. This determines whether the engine start is authorised or
denied.
After more than five consecutive failed authentication attempts, the injection computer goes into protection (anti-
scanning) mode and no longer tries to authenticate the UCH computer. It only leaves this mode when the following
sequence of operations is carried out:
– the ignition is left on for at least 20 seconds,
– the message is switched off,
– the end of the injection computer self-feed is adhered to (the length of time varies depending on engine
temperature).
After this, one and only one authentication attempt is allowed. If this fails again, repeat the sequence of operations
described above.
If the injection computer still fails to unlock, contact the Techline.
Impact detected
If an impact has been stored by the injection computer, turn off the ignition for 10 seconds, then switch it back on to
start the engine. Clear the faults using the control RZ001 Fault memory.
ENGINE SPEED MANAGEMENT
Engine speed management is based on the following programs:
– Engine speed management when starting
– Engine speed management according to engine vibrations
– Idle speed management
– Engine speed restriction
– Engine speed management according to its status
Engine speed management when starting
This programming is used:
– To set the injection timing when starting, using the TDC (Top Dead Centre) sensor
– To calculate the amount of fuel to be injected into the cylinders to avoid flooding the engine.
Preventive correction of engine speed linked to vibrations
Programming that enables user comfort to be optimised during acceleration or deceleration which causes a harsh
change in engine torque and therefore vibration in the driveshaft. Torque management is important during these
situations.
Curative correction of engine speed linked to vibrations
This programming is used to absorb the oscillations in engine speed caused by vibration in the driveshaft.WARNING
Disconnect the injection system computer when carrying out any welding work on the vehicle.

Idle speed management
This programming is used to calculate the adapted idle speed according to the conditions of use (cold engine, air
conditioning requests, electrical consumer use etc.).
Air supply
This is managed by a motorised throttle valve which is controlled by the injection computer.
The injection computer also performs the following tasks using the motorised throttle:
– management of valve oscillations which can produce undesirable torque,
– management of valve movement subject to mechanical faults when the valve reaches its mechanical boundaries,
– management of acoustic faults by limiting throttle opening at a certain engine speed and when stopping the engine.
Torque management
The torque structure is the system for managing engine torque. It is necessary for some functions such as the
electronic stability program (ESP), automatic transmission (BVA) or sequential gearbox (BVR).
Each computer (ESP, sequential gearbox, automatic transmission) sends a request for torque via the multiplex
network to the injection computer. This arbitrates between the various torque requests and the driver's request
(made via the accelerator pedal or the cruise control/speed limiter).
The result of this arbitration gives the torque setpoint. The computer then calculates the throttle position setpoint, the
ignition advance and the wastegate setpoint (if a turbocharged engine) in order to provide the necessary torque.
Ignition management
Management of ignition advance enables the combustion quality to be managed and therefore engine operation to
be optimised. For a positive advance, the ignition point will be before TDC*, however the advance can have a
negative value.
TDC*: Top Dead Centre.
Fuel supply management
The fuel pump ensures the supply of fuel. It is activated for one second each time the + after ignition feed is switched
on. It ensures the correct level of pressure in the circuit and thereby achieves correct engine starting, particularly if
the vehicle has not been used for a long time. When the engine is running, the pump relay is controlled and
therefore the pump is always active.
The petrol vapour absorber enables petrol vapour to be collected in order to limit its release into the atmosphere.
Richness adjustment
Richness is managed using the upstream and downstream oxygen sensors located on the exhaust. For the sensors
to be operational quickly, they need to be heated by the exhaust gas and by a resistor internal to the sensor. These
sensors reflect the efficiency of combustion and, using information sent to the computer, they enable the quantity of
fuel injected to be managed in order to meet the emission control standards and to ensure optimum engine
operation.

Engine temperature management
The engine is cooled by a 2-speed fan assembly.
To cool the engine, the first speed of the fan assembly is activated if the coolant temperature exceeds 99°C or 94°C
(F4R400/402/403 engines), then the second speed is activated if the temperature exceeds the 102°C or 97°C
(F4R400/402/403 engines). A "very high temperature" warning light illuminates on the instrument panel if the
temperature exceeds 118°C or 113°C (F4R400/402/403 engines).
