COMPUTER REPLACEMENT, PROGRAMMING AND REPROGRAMMING OPERATIONS
Before reprogramming or removing the computer in After-Sales operations, save the following data to the
diagnostic tool:
– The C2I parameters (individual injector correction) and the engine adaptives using command SC003 Save
computer data.
The system can be reprogrammed with the diagnostic socket using the RENAULT CLIP diagnostic tool
(Consult Technical Note 3585A, Computer programming and reprogramming procedure, and follow the
instructions given by the diagnostic tool).
Any time the computer has been reprogrammed
– Use the diagnostic tool command SC001 Enter saved data to restore the C2I and the engine adaptives.
– Use command AC028 Static test to reinitialise the computer (fan assembly, etc.).
– When changing the pump, refer to the high pressure pump replacement procedure (consult Technical Note 5011A,
Repriming Delphi high pressure pumps on K9K engines).
– Switch the ignition off and then on again.
–Activate the starter without releasing the key until the engine starts (the engine start time can be up to 20
seconds).
– Stop the engine (to initialise the computer) and wait 30 seconds.
– Switch the ignition on again and use the diagnostic tool to carry out the following steps:
– Run command VP010 Enter VIN.
– After injection system programming, stored faults may appear on other computers. Clear the memory of these
computers. IMPORTANT:
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.
IMPORTANT
– Switch on the diagnostic tool (mains or cigarette lighter supply).
– Connect a battery charger.
– Switch off all electrical consumers (lights, interior lights, air conditioning, radio/CD, etc.).
– Wait for the engine to cool (engine coolant temperature below 60°C and air temperature below 50°C).

NOTESPriority when dealing with a number of faults:
- Deal first with fault DF113 Sensor supply voltage.
See Technical Note Wiring Diagrams of the vehicle concerned.
Check the connection and condition of the EGR valve connector, component code 169.
Check the connection and condition of connector B (brown 48-track) of the computer, component code 120.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check for +5 V on connection 3GC of component 169.
Check for earth on connection 3JM of component 169.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the insulation and continuity of the following connections:
–3GC between components 169 and 120,
–3EL between components 169 and 120,
–3JM between components 169 and 120.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the resistance of the EGR valve, component code 169:
– with the engine stopped, the EGR valve will be closed (unless there is a fault),
– wait for the ambient temperature around the valve to stabilise (approximately 20°C),
– measure the resistance between connections 3FB2 and 3GB. The resistance must be between
7.54 Ω < R < 8.5 Ω (at 20°C),
– measure the resistance between connections 3GC and
3JM. The resistance must be between
2.4 KΩ < R < 5.6 KΩ (at 20°C),
– measure the resistance between connections 3JM and 3EL, the resistance should be between
800 Ω < R < 3.6 KΩ (at 20°C),
if the value is not correct, replace the EGR valve, component code 1460 (see MR 364 (Mégane II), MR 370
(Scénic II), Mechanical, 14A, Emission control, Exhaust gas recirculation solenoid valve: Removal -
Refitting). If the EGR valve was replaced, use command RZ002 EGR adaptives to reinitialise the EGR valve
offsets.
If the fault is still present, contact the Techline.
