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 – Replacement of components13B
If no communication is possible with the injection computer during reprogramming or programming:
●Clear the programming using command RZ019 Reinitialise programming.
●Clear any faults using command RZ001 Fault memory.
●Enter the V.I.N. using command SC013 Enter VIN code.
●Perform a powerlatch.
●Perform a detection of the cruise control - speed limiter and the air conditioning:
– 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.
– Air conditioning in the ON position.
●For Kangoo II, program the values for fast idle speed (if equipped) and vehicle speed restriction (if equipped)
using commands SC041 Modification of commercial vehicle idle speed and SC040 Speed limiter.
●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.
If the injection computer is faulty, contact the Techline (and refer to the fault finding log).

COMPUTER REPLACEMENT AND PROGRAMMING OPERATIONS
The system can be programmed via the diagnostic socket using the RENAULT CLIP diagnostic tool (see
Technical Note 3585A, Computer programming and reprogramming procedure).
While the computer is being programmed the fan assemblies are triggered automatically.
Before any replacement and programming of the computer:
– When possible, back up the old computer data (engine adaptives) in the diagnostic tool, by performing
command SC003 "Computer data backup".
After the computer has been programmed:
– Switch the ignition off and then on again.
– Use the diagnostic tool to carry out the following procedures:
– Run command RZ019 Reinitialise programming.
– Run command SC001 Write saved data to restore the engine adaptives,
– Start the engine. Important: the starting phase can last up to 30 seconds.
– Stop the engine (to initialise the computer) and wait 30 seconds.
– Switch on the ignition again and use the diagnostic tool to carry out the following steps:
– Run command SC013 Enter VIN code.
– After the injection has been programmed, stored faults may appear on other computers.
– Clear the fault memory of these computers.
– Carry out a road test followed by a complete check with the diagnostic tool.
After the computer has been programmed:
– Switch the ignition off and then on again.
– Use the diagnostic tool to carry out the following procedures:
– Use command RZ019 Reinitialise programming.
– Use command SC001 Write saved data to restore the engine adaptives.
– Select the UCH field,
– In the repair mode, perform command SC017 Programming injection immobiliser code and follow the
indications provided by the diagnostic tool (command SC017 Programming injection immobiliser code is
accessible in the menu "Secure programming").
– Switch the ignition off and then on again.
– Select the INJECTION field and check ET006 Code programmed.
If ET006 is "YES":
– Start the engine. Important: the starting phase can last up to 30 seconds.
– Stop the engine (to initialise the computer) and wait 30 seconds.
– Switch on the ignition again and use the diagnostic tool to carry out the following steps:
– Perform command SC013 Enter VIN code.
– After the injection has been programmed, stored faults may appear on other computers.
Clear the fault memory of these computers.
If ET006 is: "NO":
– Rerun command SC017 Programming injection immobiliser code and follow the instructions provided by the
diagnostic tool.
– Repeat the method described above.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).

Check the continuity, insulation and the absence of interference resistance on the following connections:
–3YD between components 1290 and 120,
–3AAM between components 1290 and 120,
–3TL between components 1290 and 120.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Connect a pressure gauge (fitted with a manual pump) to the sensor.
