4. Engine coolant temperature management
Engine cooling is provided by 1 or 2 fan assemblies (depending on the vehicle layout). The injection computer
requests the UPC to actuate them via the multiplex network.
To provide cooling:
Engine running, GMV1 is requested when the coolant temperature exceeds 99 °C and stops when the coolant
temperature falls below 96 °C. GMV2 is requested when the coolant temperature exceeds 102 °C and stops when
the coolant temperature falls below 99 °C.
With the engine off, only fan assembly 1 may be activated to provide the anti-percolation function (if engine is
stopped when very hot). The anti-percolation function is active with the ignition off for a determined period. During
this period, fan assembly 1 is requested if the coolant temperature exceeds approximately 100 °C and is shut down
if the coolant temperature drops below around 95 °C.
If a fault is detected on the coolant temperature sensor circuit, then fan assembly 1 is requested to operate
continuously.
If the engine coolant temperature goes beyond the warning threshold of 11 8 ° C, the injection computer requests the
instrument panel computer via the multiplex network to illuminate on the coolant temperature warning light until the
coolant temperature falls back below 115 ° C.
In addition to the engine requirements, the injection computer centralises the cooling requirements for the Air
conditioning and BVA/BVR functions.
5. Air conditioning function
The S3000 computer manages a cold loop air conditioning system.
– air conditioning request via multiplex connection,
– acquisition of air conditioning circuit pressure,
– vehicle speed
– air conditioning compressor control,
– fan assembly control request by Protection and Switching Unit.
The injection computer recovers the power absorbed by the air conditioning compressor and the fast idling speed
request 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,
– sturdier engine to torque bucking caused by compressor activation,
– helping the alternator.
Requests for fan assembly 1 and/or fan assembly 2 are recovered based on the air conditioning circuit pressure and
the vehicle speed. In short, the lower the speed and the higher the pressure, the greater the fan assembly requests.

8. Mileage travelled with fault
These two parameters PR105 Distance travelled with OBD fault warning light on and PR106 Distance travelled
with fault warning light on are used to count the distance travelled with one of the injection fault warning lights lit:
level 1 fault warning light (amber) as well as the OBD warning light.
These counters can be reset to 0 using the diagnostic tool (clear faults command).
9. Inter-system engine functions
The inter-system connections concerning the particular requirements of engine management are as follows:
–OBD warning light illumination request by the instrument panel computer to prevent a pollution fault,
–level 1 warning light illumination request to warn of an operating safety fault relating to the injection system,
–level 2 warning light illumination request to warn of an operating safety fault or provide an engine
overheating alert,
– request for fan assembly activation for engine cooling, but also for the air conditioning and automatic
gearbox,
– air conditioning compressor shut-down request for engine programming requirements such as pulling away,
performance, anti-stalling, overspeed, etc.
– passenger compartment heating resistor shut-down or fixing request for engine programming requirements
such as pulling away, performance, anti-stall, overspeed, etc.

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.

2. PROGRAMMING
Programming the flywheel target
– Decelerate a first time with injection cut-off (i.e. feet off the brake, accelerator pedal and clutch pedals) between
3500 and 3000 rpm, in 3rd gear for a manual gearbox and 2nd for automatic transmission, for at least 5 seconds.
– Decelerate a second time with injection cut-off (i.e. feet off the brake, accelerator pedal and clutch pedals) between
2400 and 2000 rpm for K4 engines and between 1800 and 1400 rpm for R4R engines, in 3rd gear for a manual
gearbox and 2nd for automatic gearbox, for at least 5 seconds.
Check the programming using ET089 Flywheel target programming.
Programming the throttle end stops
When replacing the computer or the motorised throttle valve, with the ignition on, wait 30 seconds so that the
computer may program the MAX and MIN limits, then switch off the ignition and wait 30 seconds for the end of the
Power Latch, so that the computer may store the programmed limits.
Check the programming using ET051 Throttle stop programming.
