2. Role of components, operating strategy
Engine immobiliser
The Verlog 4 type immobiliser function is managed by the UCH computer and the engine management computer.
Before any starting request, the engine management computer is protected.
When a starting request is made, the injection computer and the UCH exchange authentication data via the multiplex
network; this determines whether the engine start is authorised.
After more than 5 consecutive failed authentication attempts, the engine management computer goes into protection
(antiscanning) mode and no longer tries to authenticate the UCH computer. It only exits this mode when the
following sequence of operations occurs:
– the ignition is left on for at least 20 seconds,
– the message is switched 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 impact has been stored by the injection computer, switch off the ignition for 10 seconds, then switch it back on
so that the engine can be started. Clear the faults.
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) and the automatic gearbox.
Each inter-system (ESP and automatic gearbox) sends a request for torque via the multiplex network to the injection
computer. It arbitrates between the inter-system torque requests and the driver's request (pedal or cruise control/
speed limiter). The result of the arbitration gives the torque setpoint. The torque structure uses the torque setpoint to
calculate the throttle position setpoint, the advance and, if there is turbocharging, the turbocharger valve setpoint
(wastegate) for engines fitted with a turbocharger. WARNING
Disconnect the injection computer when carrying out any welding work on the vehicle.

6. Defect modes
Motorised throttle valve
In defect mode, the motorised throttle valve can have 6 different statuses.
Any entry into type 1 to 5 defect mode always leads to the application of type 6. Type 1The throttle opening is less than the Safe mode position. The throttle is no longer activated and is
automatically in Safe mode. The ESP, distance control and cruise control/speed limiter systems are
disabled. The automatic transmission is in "Safe mode".
Type 2The throttle opening is no longer actuated. The engine speed is limited by injection cut-off.
Type 3Defect mode is associated with restructuring of the pedal setpoints (constant pedal setpoint for each
gear).
Type 4The associated defect mode restricts the throttle opening. The maximum throttle valve opening
threshold results in a speed of below 54 mph (90 km/h).
Type 5The computer no longer processes torque changes requested by the ESP, distance control, cruise
control/speed limiter and automatic gearbox systems. This defect mode results from a computer
malfunction, or a fault with the manifold or turbocharging pressure sensor. The system then only uses
the accelerator pedal signal. The ESP, distance control and cruise control/speed limiter systems are
disabled. The automatic transmission is in "Safe mode".
Type 6The turbocharging valve no longer works.

Fault finding - Replacement of components
1. COMPUTER REPLACEMENT OR REPROGRAMMING OPERATIONS
The system can be programmed and reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic
tool (Consult Technical Note 3585A or follow the instructions provided by the diagnostic tool).
Whenever the computer has been programmed, reprogrammed or replaced:
–Switch off the ignition.
–Start and then stop the engine (to initialise the computer) and wait 30 seconds.
–Switch the ignition back on and use the diagnostic tool to carry out the following steps:
– use command VP020 Enter VIN.
– deal with any faults declared by the diagnostic tool. Clear the computer memory.
– program the flywheel sensor target and throttle stops,
– carry out a road test followed by another check with the diagnostic tool. IMPORTANT
–Switch on the diagnostic tool (mains or cigarette lighter supply).
–Connect a battery charger (during the entire computer (re)programming procedure, the engine fan
assemblies are triggered automatically).
–Observe the engine temperature setpoints given on the diagnostic tool before (re)programming.
–Cut off all the electrical consumers (interior lighting, air conditioning, radio, etc.).
Operations to be carried out before the injection computer is reprogrammed:
Before reprogramming the injection computer, move the main Cruise control/Speed limiter switch to the rest
position. The information about the cruise control or the speed limiter displayed on the instrument panel
disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the Cruise control/Speed limiter function will not be operational.
The procedure for resetting the function is as follows:
Vehicle ignition on.
– Position the main switch in rest position (the computer then detects the rest position).
– Position the switch in Cruise control position to activate the Cruise control function.
– Position the switch in Speed limiter position to activate the Speed limiter function.
IMPORTANT
It is not possible to try an injection computer coming from the Parts Department because it will no longer be
possible to use it on another vehicle.

NOTESPriority when dealing with a number of faults:
Deal firstly with fault DF084 Actuator relay control circuit or DF046 Battery voltage
if they are present or stored.
Special note:
–level 1 fault warning light illuminated.
– throttle valve defect mode types 1, 2 or 4.
Check the cleanliness and condition of the throttle valve connections.
Check the cleanliness and condition of the pedal potentiometer connections.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Repair if necessary.
Sensor feed No. 1 is reserved for the following components:
– inlet manifold pressure sensor
– turbocharger pressure sensor (F4RT 774 and 776 only)
– pedal potentiometer gang 2,
– coolant pressure sensor,
– Cruise control/Speed limiter buttons,
– upstream and downstream O
2 sensors.
To locate any internal fault on one of the sensors with a 5V supply (short circuit), disconnect each of the sensors
on the list above in turn, checking after each disconnection whether the fault changes status from present to stored.
If the faulty sensor is located, check its connections and that it is in order.
