Air conditioning function
The SIM32 computer manages a "Cold Loop" type air conditioning system:
–request for air conditioning by logical link,
–acquisition of pressure in the air conditioning circuit,
–vehicle speed
–air conditioning compressor control,
–fan unit control for the requirements of this function.
The injection computer reconstitutes the power absorbed by the air conditioning compressor and fast idle speed
requests by 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,
–more engine ruggedness due to torque hesitation caused by the compressor clutching and declutching,
–helping the alternator.
Fan unit 1 and/or 2 requests are reconstituted according to the pressure in the air conditioning circuit and the vehicle
speed. In summary, there are more fan unit requests when the speed is low and the pressure is high.
OCS - Customised Oil Change Interval (does not concern Vdiag 44 and 4C).
This program takes into account the driving style of the user to warn him of the need for an oil service. It counts the
number of revs per minute since the last oil service, corrected by a factor dependent on the oil temperature. When
this number of revs per minute exceeds a certain threshold, the customer is alerted by a message on the instrument
panel informing him that an oil service is required.
After the oil service, the user must reset the oil service interval on the instrument panel.
To find out if the engine concerned uses this programming, consult ET840 Customised Oil Change Interval.
OBD
The OBD programs are as follows:
–catalytic converter fault finding,
–upstream sensor operational fault finding,
–misfire fault finding,
–fuel supply system fault finding.
The misfiring and fuel supply system fault finding is performed continuously. The operational fault finding for the
upstream sensor and the catalytic converter can be only be carried out once per journey, and can never take place
at the same time.

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).

–Check the cleanliness of the air filter.
–Replace the filter if necessary.
–Check that the air inlet circuit is not blocked.
The turbocharging system must be perfectly sealed, from the exhaust manifold to the turbocharger, from the
turbocharger to the heat exchanger and from the heat exchanger to the throttle valve.
Check that there are no air leaks:
–around the turbocharger pressure sensor,
–around the air temperature sensor.
Check absence of leaks in the wastegate capsule pressure circuit connected to the turbocharger system.
Check that the air-air heat exchanger is not clogged (presence of oil).
If there is oil in the heat exchanger, the turbocharger is certainly damaged.
Using a pressure/vacuum pump, check that the turbocharger protection and turbocharging valve capsule
diaphragms do not leak.
Check the condition the motorised throttle valve in terms of clogging.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

* OCS: Oil Control System.
PR873OIL OXIDATION SIGNAL
(except D7F800 and D4F772)
PARAMETER
DEFINITIONThis parameter indicates the distance of the vehicle when the oil dilution threshold is
reached.
NOTESOnly apply the interpretation of this parameter if the OCS* strategy is activated on the
instrument panel. Check the configuration reading LC106 OCS on the instrument panel
computer is WITH.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
The oil condition is calculated by the oxidation program in the injection computer, according to the number of
engine revolutions.
When this count reaches a certain threshold before the end of the oil service period, the injection computer
sends a signal to the instrument panel, which will display service due. Parameter PR873 corresponds to
the vehicle mileage at the time this signal is sent.
Then the instrument panel computer deducts 900 miles (1500 km) before displaying the message Service required.
IMPORTANT:
When the message Service due appears on the instrument panel, the customer must have the oil changed within
the remaining 900 miles (1500 km).
