EOBD* management:
The OBD (On Board Diagnostic) system enables the detection of any faults relating to the vehicle emission control
system (OBD EURO IV emission control standards exceeded).
This system should be active for the entire life of the vehicle.
1. Conditions causing an OBD fault
An OBD fault will be detected after 3 driving cycles and the following parameters will be registered in the computer:
–engine load,
–vehicle speed
–air temperature
–coolant temperature,
–turbocharging pressure,
–rail pressure,
–air flow,
–distance travelled in miles by the vehicle since activation of the OBD warning light.
It allows the driver to know whether the vehicle has a fault directly linked to the emission control system.
2. System faults indicated by the OBD
Only a few faults are indicated by the OBD system:
–DF001 Coolant temperature sensor circuit.
–DF003 Atmospheric pressure sensor circuit.
–DF011 Sensor feed voltage no. 1.
–DF012 Sensor feed voltage no. 2.
–DF013 Sensor feed voltage no. 3.
–DF038 Computer in 6.DEF EEPROM fault.
–DF040 Cylinder 1 injector circuit in CO Open circuit.
–DF041 Cylinder 2 injector circuit in CO Open circuit.
–DF042 Cylinder 3 injector circuit in CO Open circuit.
–DF043 Cylinder 4 injector circuit in CO Open circuit.
–DF054 Turbocharging solenoid valve control circuit in CC.0 Short circuit to earth.
–DF056 Air flow sensor circuit.
–DF209 EGR valve position sensor circuit.
–DF621 EGR valve jammed open.
Some repair operations require programming to ensure that certain engine components function correctly.
Follow the programming procedures (see Replacement of components), if replacing the exhaust gas
recirculation valve or an injector.

3. Conditions for clearing an OBD fault
An OBD fault is cleared in several steps.
The fault present in the diagnostic tool is not stored (following repair) until after 3 trips with the vehicle.
The OBD warning light will only light up after these 3 driving cycles.
The warning light coming on does not always mean that there is a fault on the system.
In order that the OBD fault and the display parameters are cleared from the computer, the system needs to
go through 40 engine heating cycles.
An engine heating cycle is a driving cycle during which:
–the engine coolant temperature reaches at least 71.1 ˚C,
–the engine coolant temperature varies by 22.2 °C in relation to the engine starting temperature.
If one of these conditions is not fulfilled, the OBD fault will still be present or stored in the injection computer.

COMPUTER REPLACEMENT OR REPROGRAMMING
Operations to be carried out before reprogramming the injection computer:
Before reprogramming the injection computer, move the main CC/SL 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.
–Move the cruise control/speed limiter switch to the rest position (the computer detects the rest position at that
moment).
–Move the cruise control/speed limiter switch to the Cruise control position to activate the Cruise control function.
–Move the cruise control/speed limiter switch to the Speed limiter position to activate the Speed limiter function.
Two operations must be performed when replacing or reprogramming the computer:
SC003 Save computer data and SC001 Enter saved data.
–Use SC003 before the computer is replaced or reprogrammed. This enables certain data to be saved in the
diagnostic tool so that the new computer* can be reconfigured like the old one. The saved data are: injector
codes, EGR programming, vehicle options.
–Run SC001 after the computer is replaced or reprogrammed. It enables you to rewrite the data (saved by
command SC003) to the new computer*.
If you cannot establish dialogue with the computer being replaced: you will not be able to save anything. After
replacing the computer, enter the IMA code of each injector manually, reading the code on each injector (see
INJECTOR REPLACEMENT).
Exhaust gas recirculation valve data is programmed automatically the 1
st time the new computer is switched on*.
* new computer or reprogrammed computer. 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 < 60˚ and air temperature < 50˚).
–The GMV are activated automatically when the computer is being reprogrammed.

REPLACING THE INJECTORS
After replacing one or more injectors, re-enter the IMA codes.
The system must be configured via the diagnostic socket using the RENAULT CLIP diagnostic tool.
→ PROCEDURE to be followed after one or more injectors are replaced:
IMPORTANT
Cylinder no. 1 is located at the engine flywheel end.
–make a note of the IMA code(s) engraved on the injector body,
–enter these codes in the computer using command SC002 Enter injector codes, then follow the instructions given
by the diagnostic tool,
–once the command has finished,
–switch off the ignition,
–wait 1 min before switching on the ignition again,
–return to fault finding mode,
–select the Computer identification function from the main screen,
–check that the injector codes entered into the computer match those found on the bodies of the injectors:
–if the codes do not match, repeat the procedure for command SC002 Enter injector codes;
–if the codes do match, check system faults and clear any stored faults;
–if there are faults, deal with the present faults,
–clear the faults from the computer memory.
Carry out a road test followed by a complete check with the diagnostic tool.
End of operation.Note:
The IMA coding (individual injector correction) is a calibration made in production on each injector to adjust
the flow accurately.
These correction values are etched onto the Bakelite body of each injector (6 alphanumeric characters) and then
entered into the computer which then controls each injector taking into account their manufacturing variation.
IMPORTANT
Engines can only operate correctly if the correct IMA codes have been entered.
If no code has been entered or if an invalid code has been entered, the fault DF276 Injector code
programming, is present and the engine will be in defect mode (speed heavily limited).
If another injector's code has been entered, the system will accept it but will make the wrong correction.
This could lead to engine damage, loss of performance and excessive pollution.
Always use the correct injector codes for the engine cylinder/computer.
