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.

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.

RUN OBD TEST: CATALYTIC CONVERTER
NOTESIMPORTANT:
Do not perform this test with a new catalytic converter.
Repair all the electrical faults and clear them from the memory.
Program the flywheel target ET089 Programming the engine flywheel target.
Check the appearance and condition of the catalytic converter.
Check there are no air leaks, thermal shock, misfiring, coolant or oil consumption.
It is preferable to run this command with a warm engine. This reduces the time it takes
for the catalytic converter to heat up.
The purpose of this command is to determine the condition of the catalytic converter
Procedure:
– Engine stopped.
– Run command SC006.
– Start the vehicle without losing the + after ignition feed
– Wait for the command result.
At the end of this test, four different results are possible:
–Status 1: Fault finding not carried out/impossible to obtain the necessary conditions.
–Status 2: Component in an average condition.
–Status 3: Component in good condition.
–Status 4: Component in poor condition.
When the command is complete and after the result has been read, stop the engine and start it again to obtain the
conditions relating to normal use.
If the result is Status 1: check for any faults, and the engine flywheel target programming using ET089.
If the result is Status 2 or Status 4: replace the catalytic converter.
If the result is Status 3: the catalytic converter is in good condition.

RUN OBD TEST: O2 SENSOR
NOTESRepair all the electrical faults and clear them from the memory.
Program the flywheel target ET089 Programming the engine flywheel target.
It is preferable to run this command with a warm engine. This reduces the time it takes
for the catalytic converter to heat up.
The aim of this command is to detect a fault causing the EOBD* threshold for pollutant emissions to be exceeded.
There are two kinds of oxygen sensor damage:
– mechanical damage to the component (breakage, cut in wire) which leads to an electrical fault,
– chemical or thermal damage to the component leading to a slower response time of the sensor and to the
increase in the average reaction time.
Procedure:
– Engine stopped.
– Run command SC007.
– Start the vehicle without losing the + after ignition feed
– Wait for the command result.
Fault finding is entirely autonomous. When completed, the throttle control ceases and the engine returns to idling
speed regulation operation.
At the end of this test, four different results are possible:
–Status 1: Fault finding not carried out/impossible to obtain the necessary conditions.
–Status 2: Component in an average condition.
–Status 3: Component in good condition.
–Status 4: Component in poor condition.
When the command is complete and after the result has been read, stop the engine and start it again to obtain the
conditions relating to normal use.
If the result is Status 1: check for any faults, and the engine flywheel target programming using ET089.
If the result is Status 2 or Status 4: replace the sensor.
If the result is Status 3: the sensor is in good condition.
