Fault finding – Replacement of components
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).

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).

364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel fuel injector: Removal - Refitting) and the
injection computer connector, component code120 (see MR 392, 385, 364, 370 and 417, Mechanical, 13B,
Diesel injection, Diesel injection computer: Removal - Refitting).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s); otherwise, replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3KW between components 193 and 120,
–3CR between components 193 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.
Measure at ambient temperature (approx. 20°C), allow the engine to cool down for at least 30 minutes.
Measure the resistance between connections 3KW and 3CR for injector 1, component code 193.
If the resistance is not between 150 kΩ and 250 kΩ, replace injector 1 (see MR 392, 385, 364, 370 and 417,
Mechanical, 13B, Diesel injection, Diesel injector: Removal - Refitting).
Apply test 7 Incorrect injection quantity.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
