For vehicles with key/radio frequency remote control, use the key to switch off the ignition.
For vehicles with a Renault card:
– press the Start button twice briefly (less than 3 seconds),
– ensure that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.
Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of faults should be considered when using the diagnostic tool after the + after ignition
feed is switched on (without any action 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 on these lines (corrosion, bent pins, etc.),
– the resistance of the faulty component,
– 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:
– carry out 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 repairs.
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
bycustomer complaints.
A synopsis of the general procedure to follow is provided on the following page in the
form of a flow chart.

Fault finding – Function13B
MANAGEMENT OF PRE/POSTHEATING
Pre-postheating management involves controlling the heater plugs and the heater plugs indicator light on the
instrument panel (via the multiplex network). The heater plugs are activated by a preheating unit and the power is
provided by the battery.
When the ignition is switched on, the preheating period is activated; the indicator light comes on for a period
dependent on the battery voltage, atmospheric pressure and coolant temperature.
When the coolant temperature is below a certain threshold, a postheating function enables combustion stability,
and thereby engine operation, to be improved (reduction in unburned fuel and pollutant emissions).
MANAGEMENT OF ENGINE COOLANT TEMPERATURE
Engine cooling is guaranteed by a 2-speed fan assembly (GMV) (slow: GMV1 and fast: GMV2).
The injection computer requests the UPC to actuate them via the multiplex network.
To provide cooling:
– Engine running:
GMV1 is activated when the coolant temperature exceeds 96°C and is deactivated when it drops below 94°C.
GMV2 is activated when the coolant temperature exceeds 104°C and is deactivated when it drops below 102°C.
If the engine coolant temperature exceeds the warning threshold of 120°C, the injection computer requests the
instrument panel computer, via the multiplex network, to switch on the coolant temperature warning light. The
warning stops if the coolant temperature drops below 117 ° C.
If the engine coolant temperature exceeds the threshold of 11 5 ° C, the injection computer requests the UPC
computer, via the multiplex network, to switch off the air conditioning compressor so as to reduce the load on the
engine and attempt to limit its rise in temperature. The cut-off request is cancelled if the coolant temperature drops
below 110°C.
If a fault in the coolant temperature sensor circuit is detected, the injection computer requests that the coolant
temperature warning light is lit and that GMV2 is activated.
In addition to engine management, the injection computer centralises the cooling requirements for the air
conditioning and automatic gearbox/sequential gearbox functions (if fitted to the vehicle).
OTHER HOSTED FUNCTIONS
The other functions hosted by the computer are:
– Multiplex line.
– ADAC (Trip Computer).
– Trip Computer Display.
– Engine immobiliser.
– Airbag.
– Engine stop management.
– Starter management.
– Air conditioning.
– Cruise control/speed limiter.

COMPUTER REPROGRAMMING OPERATIONS
The system can be reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic tool (see
Technical Note 3585A, Computer programming and reprogramming procedure).
Note:
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.
– Main switch in rest position (the computer then detects the rest position).
– Switch in Cruise control position to activate the Cruise control function.
– Switch in Speed limiter position to activate the Speed limiter function.
While the computer is being reprogrammed the fan assemblies are triggered automatically.
Before reprogramming the computer:
– Save the computer data to the diagnostic tool (engine adaptives) by performing command SC003 Save
computer data.
After any computer reprogramming operation:
– Switch the ignition off and then on again,
–Use the diagnostic tool to carry out the following procedures:
– run command RZ019 Programming reinitialisation.
– run command SC001 Write saved data to restore the engine adaptives,
– run command SC013 Enter VIN,
– start the engine (warning: the start-up phase may last up to 30 seconds),
– after injection computer reprogramming, stored faults may appear in other computers. Clear the fault memory of
these computers,
– carry out a road test followed by another check with the diagnostic tool.
DO NOT CARRY OUT ANY INJECTOR CODE WRITING ON THE SIEMENS SID304 AND 301 INJECTION
SYSTEMS.IMPORTANT
Switch on the diagnostic tool (mains or cigarette lighter supply).
Connect a battery charger.
Switch off all the electrical consumers (lights, interior lighting, air conditioning, radio CD, etc.).
Wait for the engine to cool (engine coolant temperature < 60 °C and air temperature < 50 °C).

●For Vdiag 45, 49 and 4D, carry out a particle filter regeneration using command SC017 Particle filter
regeneration (see Interpretation of commands).
●For Clio III, Modus, Megane II and Scenic II vehicles:
– If the configuration reading LC106 O.C.S. is" WITH" (check in the instrument panel computer), perform
an engine oil change and initialise the value of the oil service interval using the instrument panel.
●For Kangoo II:
– Change the engine oil and initialise the value of the oil change interval using the instrument panel.
IMPORTANT
The injection computer retains the immobiliser code for life.
The system has no security code.
It is forbidden to perform tests with computers borrowed from the Parts Department or from another vehicle
which must then be returned.
These computers are hard-coded.

REPLACING THE EGR VALVE (EXHAUST GAS RECIRCULATION VALVE)
After replacing the EGR valve, the computer must store the offset of the new valve (to 0 km), as well as the offset
measured at the time of the last engine cut-off (power-latch). With these data, the computer can detect clogging or
blocking of the EGR valve.
When the valve is replaced, clear the stored offsets so that the program uses the new valve’s offset value. The data
associated with this programming is combined under the EGR programming function.
Procedure to follow after replacement of the EGR valve:
– Select the CLEAR menu.
– Run fault clearing command RZ002 EGR adaptives,
– switch off the ignition,
–wait 30 seconds (auto-supply phase of the computer),
– start the vehicle to allow programming of the EGR valve,
– view parameters PR400 New EGR valve offset and PR129 Last EGR valve offset,
– if the reinitialisation was correctly performed then 0.6 V < PR400 = PR129 < 1.9 V.
REPLACEMENT OF PUMP, INJECTORS, RAIL + RAIL PRESSURE SENSOR OR COMPONENT OF THE LOW
PRESSURE CIRCUIT (DIESEL FILTER etc.).
After replacement of one of these components, carry out clearing using RZ004 Pressure regulation adaptives.
REPLACEMENT OF THE PARTICLE FILTER (Only Vdiag 45, 49, 4D)
After replacement of the particle filter, clear the fault DF308 Clogged particle filter if it is present or stored using
command RZ001 Fault memory. 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.
