6. Defect modes
Motorised throttle valve
In defect mode, the motorised throttle valve can have 6 different statuses.
Any entry into type 1 to 5 defect mode always leads to the application of type 6. Type 1The 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 2The throttle opening is no longer actuated. The engine speed is limited by injection cut-off.
Type 3Defect mode is associated with restructuring of the pedal setpoints (constant pedal setpoint for each
gear).
Type 4The associated defect mode restricts the throttle opening. The maximum throttle valve opening
threshold results in a speed of below 54 mph (90 km/h).
Type 5The 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 is in "Safe mode".
Type 6The turbocharging valve no longer works.

Camshaft dephaser:
The camshaft dephaser ET083 Camshaft dephaser in defect mode may assume two different statuses.
●Status 1
This defect mode covers all faults that affect the dephaser position measurement. The dephaser is set to the
minimum stop and the camshaft angle measurement is forced to 0.
Tooth signal fault.
Tooth/camshaft signal consistency diagnostic.
●Status 2
This defect mode covers all faults affecting the dephaser (pulley and solenoid valve). The dephaser is set to
the minimum stop.
Electrical fault finding on the solenoid valve.
Dephaser position fault finding procedure.
7. Operational safety
Warning lights illumination
The S3000 Injection system manages the illumination of three warning lights and the display of warning messages
according to the severity of the faults detected, with the aim of informing the customer and guiding 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 (level 1), the message CHECK INJECTION is lit, 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 (level 2), the red engine symbol and the word STOP (display with information
display only), appears with the message ENGINE OVERHEATING 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 gases is detected, the orange OBD warning light engine
symbol is lit:
–flashing in the event of a fault which might cause destruction of the catalytic converter (destructive misfires). If this
happens, the vehicle must be stopped immediately.
–constantly in the case of non-compliance with the anti-pollution standards (polluting misfires, catalytic converter
fault, oxygen sensor faults, inconsistency between the oxygen sensors and canister fault).

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.

Fault finding - Replacement of components
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.
* This is the moment when, during deceleration with no load, the engine drops to idling speed and recovers torque. LC158Air conditioning heating resistor management
