1. OPERATING SAFETY
Activation of the warning lights
The SIM32 injection system manages the illumination of three warning lights according to the severity of the faults
detected, to inform the customer and to assist with fault finding.
The injection computer manages the activation of the warning lights 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 activation commands are sent to the instrument panel.
Warning light illumination principle
When the ignition is switched on, the OBD (On Board Diagnostic) warning light is illuminated for approximately
3 seconds and is then extinguished.
If there is an injection fault (severity level 1), the SERVICE warning light is illuminated.
It indicates a reduced level of operation and a limited safety level.
The user must carry out repairs as soon as possible:
–motorised throttle valve,
–accelerator pedal potentiometer,
–inlet manifold pressure sensor,
–computer,
–actuator feed,
–the computer power supply,
–turbocharger pressure sensor (for D4FT 780).
For faults requiring the driver to stop the engine quickly, the severity level 2 warning light is illuminated.
If a fault causing excessive exhaust gas pollution is detected, the orange OBD warning light engine symbol is
illuminated:
–the light flashes if the fault could lead to a risk of destroying catalytic converter (destructive engine misfire). If this
happens, the vehicle must be stopped immediately.
–the light is permanently illuminated if the emission control standards are not met (pollutant engine misfire,
catalytic converter fault, oxygen sensor fault, inconsistency between the oxygen sensors and a fuel vapour
absorber fault).
Mileage travelled with fault
The parameter PR106 Mileage counter fault warning light illuminated displays the mileage covered and
illuminates one of the injection fault warning lights: fault severity level 1 (amber) and 2 (red). The parameter
PR105 Mileage counter OBD fault warning light illuminated displays the mileage covered and illuminates the
OBD warning light.
This counter is reset to 0 using the diagnostic tool via the command RZ001 Fault memory.

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.

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).
