3. INTERSYSTEM ENGINE FUNCTIONS
The intersystem connections relating to the particular requirements of the injection are as follows:
–The instrument panel computer requests illumination of the OBD warning light to warn of an emissions control fault.
–Requests illumination of the Severity level 1 warning light to warn of an operational safety fault related to the
injection system.
–Requests illumination of the Severity level 2 warning light to warn of an operational safety fault or engine
overheating.
–Requests activation of the fan assemblies (GMV) for engine cooling, but also for the air conditioning system and
sequential gearbox (BVR) functions.
–Request for air conditioning compressor switch-off for engine programming requirements such as starting,
performance, anti-stall, overspeed, etc.
–Passenger Compartment Heating Resistor cut-off or setting request for engine programming requirements such as
starting, performance, anti-stall, overspeed, etc.
–Request for gradual engagement of electrical consumers and to limit power: This last function is made possible by
the alternator being operated. This is used to improve the engine handling in critical operating phases, mainly when
idling and when starting. These requests are sent by the UCH via the CAN network where they are converted before
being sent to the alternator.

Injection computer:
The injection computer manages the entire system.
Its role is to define the engine optimum operating mode and to inform the driver (via the instrument panel, information
display, and buzzer) and to communicate with the other computers.
Fuel vapour recirculation solenoid valve:
The fuel vapour absorber works like a ''sponge'' for petrol vapours and enables gases coming from the tank to be
collected.
Upstream oxygen sensor:
This sensor measures the amount of oxygen in the exhaust gas.
The voltage supplied to the computer by the sensor indicates the amount of oxygen in the exhaust gas - a rich
mixture or a lean mixture - and a program is adopted accordingly.
Downstream oxygen sensor:
This sensor measures the amount of oxygen in the exhaust gas.
The voltage supplied to the computer by the sensor indicates the amount of oxygen in the exhaust gas - a rich
mixture or a lean mixture - and a program is adopted accordingly.
Pinking sensor:
The sensor detects engine knocking and sends its electrical signal to the injection computer.
Oil pressure sensor:
This sensor measures the engine oil pressure.
Turbocharger:
The turbocharger is used to supply the engine with more air.
Turbocharger pressure sensor:
This sensor indicates the pressure at the turbocharger air cooler outlet before the damper valve.
Ignition coil:
This acts both as an energy storage battery and a transformer. It generates high voltage ignition pulses and the
energy required to ignite the mixture.
Motorised throttle valve:
The motorised throttle valve supplies the engine with varying mixtures of fuel and air according to the load required.
This electronic control detects the position of the accelerator using a sensor (potentiometer) to inject the mixture.

1. COMPUTER REPLACEMENT OR REPROGRAMMING OPERATIONS
Computer replacement or reprogramming for engines with the OCS (customised oil change interval)
function.
For Vdiag 44 and 4C, commands SC001 and SC003 are not accessible.
The system can be programmed via the diagnostic socket using the RENAULT CLIP diagnostic tool (refer to
Technical Note 3585A, COMPUTER PROGRAMMING AND REPROGRAMMING PROCEDURE or follow the
instructions given by the diagnostic tool). Only in Vdiag 54 and certain engines in Vdiag 50:
For Vdiag 50, the procedure below should be followed only if ET840 Customised Oil Change Interval is ACTIVE.
Certain variables linked to the O.C.S and the details of the last four oil services are saved by the computer.
However, all data saved is cleared during a reprogramming operation. When replacing or reprogramming the
computer, it is necessary to save the data from the old computer so it can be written to the new computer
(or reprogrammed). To do this before changing (or reprogramming) the computer, it is necessary to run the request
SC003 Save computer data, and after it has been changed (or reprogrammed), it is necessary to run the request
SC001 Write saved data.
For Vdiag 50, if ET840 Customised Oil Change Interval is INACTIVE, commands SC001 and SC003 should
not be used.
Operations to check before reprogramming the injection computer:
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:
Ignition switched on and main switch in rest position (the computer detects rest position at that moment).
Switch in Cruise control position to activate the Cruise control function.
Switch in Speed limiter position to activate the Speed limiter function.
IMPORTANT:
–Switch on the diagnostic tool (mains or cigarette lighter supply).
–Connect a battery charger.
–Switch off all electrical consumers (lights, interior lighting, air conditioning, radio, etc.).
–Wait for the engine to cool (engine coolant temperature below 60˚C and air temperature below 50˚C).

Disconnect the battery and the fuel sender.
Check the condition of the fuel pump and sender unit connector (component code 199, for NEW TWINGO or
component code 833 (for E33, CLIO III or MODUS).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the universal bornier to check the insulation and continuity of the following connections:
●AP41 between components 199 and 247 (for NEW TWINGO),
●41B between components 199 and 247 (for NEW TWINGO),
●41A between components 833 and 247 (for E33, CLIO III or MODUS),
