Engine immobiliser
The immobiliser function is managed by the UCH and engine management computers.
Before any driver request (card + button press), the engine management and UCH computers exchange
authentication CAN frames to determine whether or not to start the engine.
After more than five consecutive failed authentication attempts, the engine management 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 60 seconds,
– ignition 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 it too fails, the sequence of operations described above must
be repeated.
If the engine management computer still fails to unlock, contact the Techline.
Impact detected
If an impact has been registered by the injection computer (Impact detected), switch off the ignition for 10 seconds
then switch it back on to start the engine. Then clear any faults.
WARNING
Disconnect the injection computer when carrying out any welding work on the vehicle.

2. OPERATIONAL SAFETY
Warning lights illumination
The S3000 injection system manages the illumination of three warning lights and the issuing of warning messages
according to the severity of the faults detected, to inform the customer and to direct fault finding.
The injection computer manages the illumination of warning lights and warning messages displayed on the instrument
panel. These warning lights illuminate during the starting phase and in the event of an injection fault or engine
overheating.
The warning light illumination signals reach the instrument panel via the multiplex network.
Warning light illumination principle
During the starting phase (START button pressed) the OBD (On Board Diagnostic) warning light comes on for
approximately 3 seconds then goes out.
If there is an injection fault (severity 1), the INJECTION FAULT written message lights up followed by the SERVICE
warning light. It indicates a reduced level of operation and a limited safety level.
The driver should carry out repairs as soon as possible.
Components involved:
– motorised throttle valve,
– accelerator pedal potentiometer,
– inlet manifold pressure sensor,
–computer,
– actuator feed,
– computer feed.
If there is a serious injection fault (severity 2), the red engine symbol and the word STOP appear (display with
information display only), with the ENGINE OVERHEATING written message followed by the STOP warning light
and a buzzer. If this happens, the vehicle must be stopped immediately.
When a fault causing excessive pollution in the exhaust fumes is detected, the orange OBD warning light, an engine
symbol, will be lit:
–flashing in the event of a fault which might irreparably damaged the catalytic converter (destructive misfire). If this
happens you must stop the vehicle immediately,
–constantly in the case of non-compliance with the anti-pollution standards (pollutant misfire, catalytic converter
fault, oxygen sensor faults, inconsistency between the oxygen sensors and canister fault).
Mileage travelled with fault
This parameter serves to measure the distance travelled with one of the injection fault warning lights on: level 1 fault
warning light (amber), coolant temperature overheating warning light, or OBD warning light.
The counter can be reset to 0 using the diagnostic tool.

Defect modes
Motorised throttle valve
In defect mode, the motorised throttle valve can have 6 different statuses.
Type 1
The 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 2
The throttle opening is no longer actuated. The engine speed is limited by injection cut-off.
Type 3
Defect mode is associated with restructuring of the pedal setpoints (constant pedal setpoint for each gear).
Type 4
The associated defect mode restricts the throttle opening. The maximum throttle valve opening threshold
results in a speed below 54 mph (90 km/h).
Type 5
The 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 system is in Safe mode.
Type 6
The turbocharging valve no longer works.

Fault finding – Replacement of components
1. PROGRAMMING, REPROGRAMMING OR REPLACING THE COMPUTER
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 for 30 seconds,
–switch on the ignition again and use the diagnostic tool to carry out the following steps:
– run command VP010 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.
2. REPLACING OR REMOVING THE TDC SENSOR
When the TDC sensor is replaced or removed, the flywheel target has to be programmed.
3. REPLACING THE MOTORISED THROTTLE VALVE
When the throttle valve is replaced, the throttle stops must be programmed.IMPORTANT
–switch on the diagnostic tool (mains or cigarette lighter supply),
–connect a battery charger (during the entire computer (re)programming procedure, the motor-driven fan
assemblies are triggered automatically),
–observe the engine temperature instructions of the diagnostic tool before (re)programming.
IMPORTANT
It is not possible to test an injection computer from the Parts Department because it can no longer be fitted on any
other vehicle.
IMPORTANT
Never drive the vehicle without having programmed the throttle stops.

Fault finding – Configurations and programming
1. CONFIGURATION
Computer configuration by automatic detection
The computer can automatically configure itself based on the sensors or vehicle options it detects.
2. PROGRAMMING
Programming the flywheel target
Accelerate up to 4000 rpm in 3rd gear then decelerate to power take-up* speed. Then repeat immediately.
Check the programming with ET089.
Programming the throttle end stops
After replacing the computer or motorised throttle valve, after switching on the ignition, wait 30 seconds for the
computer to memorise the MAXIMUM and MINIMUM stops.
Check the programming with ET051.
* This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque.

NOTESPriority for dealing with a combination of faults:
Deal with fault DF012 Sensor feed no. 2 voltage first, if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the ignition is switched on or with then engine
running at an engine speed above 600 rpm.
Special note:
– the OBD warning light is lit,
– Throttle valve defect mode types 5 and 6.
Check the cleanliness, condition and the assembly of the turbocharging pressure sensor.
Repair if necessary.
If the fault is still present, manipulate the harness so that the status changes (present  stored).
Look for any damage to the wiring harness, and check the condition and connection of the injection computer
and turbocharging pressure sensor connectors.
Repair if necessary.
If the fault is still present, check for + 5 V on track G1 and that the earth is present on track E1 of connector B of
the injection computer.
Contact the Techline if it is not correct.
If the fault is still present, disconnect the battery and the injection computer.
Check the insulation, continuity and the absence of interference resistance on the following connections:
Computer connectorB, track E1 Track 2 of the pressure sensor
Computer connectorB, track F1 Track 3 of the pressure sensor
Computer connectorB, track G1 Track 1 of the pressure sensor
Repair if necessary.
If the fault is still present, deal with the other faults then proceed to the conformity check.
AFTER REPAIRFollow the instructions to confirm the repair:
Deal with any other faults.
Clear the stored faults.
