5. FAULT FINDING LOG
You will always be asked for this log:
– when requesting technical assistance from Techline,
– for approval requests when replacing parts for which approval is mandatory,
– to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– use the proper tools.
7. FAULT FINDING
Stored faults are managed the same way for all sensors and actuators.
A stored fault is cleared after 128 recurrence-free starts.IMPORTANT!IMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the fault finding procedure, ensures a
record is kept of the procedure carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDING IS
CARRIED OUT.

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.

Defect modes
Motorised throttle valve
In defect mode, the motorised throttle valve can have 6 different statuses.
Type 1
The throttle opening is less than the Safe mode position. The throttle is no longer activated and is
automatically in Safe mode. The ESP, distance control and cruise control/speed limiter systems are
disabled. The automatic transmission is in "Safe mode".
Type 2
The throttle opening is no longer actuated. The engine speed is limited by injection cut-off.
Type 3
Defect mode is associated with restructuring of the pedal setpoints (constant pedal setpoint for each gear).
Type 4
The associated defect mode restricts the throttle opening. The maximum throttle valve opening threshold
results in a speed below 54 mph (90 km/h).
Type 5
The computer no longer processes torque changes requested by the ESP, distance control, cruise control/
speed limiter and automatic gearbox systems.
This defect mode results from a computer malfunction, or a fault with the manifold or turbocharging
pressure sensor.
The system then only uses the accelerator pedal signal.
The ESP, distance control and cruise control/speed limiter systems are disabled. The automatic
transmission system is in Safe mode.
Type 6
The turbocharging valve no longer works.

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.
