Faults
Faults are displayed as present or stored (they appeared in a certain context and have since disappeared, or they
are still present but cannot be diagnosed in the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used after the
+ after ignition feed is switched on (without acting on the system components).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
– the electrical lines which correspond to the fault,
– the connectors for these lines (for oxidation, bent pins, etc.),
– the resistance of the component detected as faulty,
– the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool when the data
is inconsistent. Therefore, this stage is used to:
– perform fault finding on faults that do not have a fault display, and which may correspond to a customer complaint.
– check that the system is operating correctly and that there is no risk of a fault recurring after repair.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
Customer complaints.
A summary of the overall procedure to follow is provided on the
following page in the form of a flow chart

Camshaft dephaser
Its role is to modify the valve timing.
The camshaft dephaser is continuously variable in operation.
In applications without a camshaft sensor, the engine phasing is controlled by software. This is the case on engines
that do not have a camshaft dephaser.
This information can be displayed by reading configuration LC008 Camshaft dephaser.
A first strategy called "Memo phasing" is applied to phase the engine management on starting according to the data
recorded when the engine last stalled. Wait for the end of auto-feed (power latch and therefore this data being
saved) before disconnecting the computer.
Then, a second program confirms the first decision. It is based on torque analysis.
The injection computer actuates a camshaft dephaser that varies according to the engine:
–K4M engine
Continuous variable inlet camshaft dephaser between 0 and 43° of the crankshaft, controlled by a solenoid
valve supplied by an opening cycle ratio circuit through the injection computer.
–F4R and F4R-T engines
Inlet camshaft dephaser controlled by a solenoid valve with an all or nothing supply from the injection
computer.
Camshaft position sensor (non-LPG K4M only)
The role of the camshaft sensor is:
– to locate the computer cylinders so that the computer correctly synchronises the sequential injection,
– checks the position of the inlet camshaft.
Motorised throttle valve
The throttle valve carries out idling speed regulation and engine air intake modulation functions. It comprises an
electric motor and two throttle position potentiometers.
When the engine is idling, the throttle position is regulated according to the idling speed setpoint. This setpoint takes
into account the major power consumers (air conditioning) and operating conditions (air temperature and coolant
temperature).

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).

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.
