2. PROGRAMMING
Flywheel target programming
(To be carried out when replacing or removing the TDC sensor).
The coolant temperature must be over 35˚C.
–Carry out an initial deceleration with injection cut-off (feet off the brake, accelerator and clutch pedals) between
3500 and 3000 rpm, in 3rd gear for at least 5 seconds for manual gearboxes.
–Decelerate a second time with injection cut-off (feet off the brake, accelerator and clutch pedals) between 2400 and
2000 rpm, in 3rd gear for at least 5 seconds for manual gearboxes.
Check the programming with ET089 Programming flywheel target: Performed.
Programming the throttle end stops
After replacement of the computer or the motorised throttle valve, with the ignition on, wait 30 seconds so that the
computer can program the Upper and Lower limits and then switch off the ignition and wait 30 seconds for the end of
the "Power Latch", so that the computer can store the programmed limits. Check the programming with ET051
Programming throttle stops: Performed.
Programming the alcohol level (only for vehicles running on Ethanol or E85 fuel)
Fuel recognition is carried out by observing the drift of the richness controller.
This can only be performed if the mixture regulation is looped (ET300 Mixture regulation).
Programming procedure:
–start the engine,
–wait for the engine coolant temperature to reach 75˚C and then check using the parameter PR064 "Coolant
temperature",
–run the engine at 1500 rpm for a period of at least 5 minutes,
–check that the programming has been carried out using status ET671 Alcohol level programming and
parameter PR743 Estimated alcohol level in tank,
–the programming is saved when the ignition is switched off. Note:
After replacement of the throttle valve run the command RZ005 Programming to erase any recorded
programming.
Note:
When the injection computer has not recognised the fuel composition, operation is faulty.

STATUS
DEFINITIONALCOHOL: This status indicates that the engine runs on ETHANOL (E85).
PETROL: This status indicates that the engine runs on petrol.
NOTESThere must be no present or stored faults.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
ALCOHOL
or
PETROLThe status ET561 is ALCOHOL if the vehicle runs on ETHANOL (E85).
The status ET561 is PETROL if the vehicle runs on petrol.
–Reprogram the alcohol level (see Configurations and programming, Alcohol
level programming):
–start the engine,
–allow the engine coolant temperature to reach 75˚C, check using parameter PR064
Coolant temperature,
–run the engine at 1500 rpm for at least 5 mins,
–check that the programming has been carried out using status ET671 Alcohol
level programming and parameter PR743 Estimated alcohol level in tank,
the programming is saved when the ignition is switched off.
If the fault is still present, contact the Techline.

ET671PROGRAMMING THE ALCOHOL LEVEL
STATUS
DEFINITIONCOMPLETED: This status indicates that the alcohol level has been programmed.
NOT COMPLETED: This status indicates that the alcohol level has not been
programmed.
NOTESSpecial notes:
Perform these checks if the statuses correspond with the system operation
programming.
There must be no present or stored faults.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
COMPLETEDStatus ET671 must be COMPLETED if the vehicle runs on alcohol.
NOT
COMPLETEDReprogram the alcohol level (see Configurations and programming, Alcohol level
programming):
–start the engine,
–allow the engine coolant temperature to reach 75˚C, check using parameter PR064
Coolant temperature,
–run the engine at 1500 rpm for at least 5 mins,
–check that the programming has been carried out using status ET671 and
parameter PR743 Estimated alcohol level in tank,
the programming is saved when the ignition is switched off.
If the fault is still present, contact the Techline.

PR743ALCOHOL LEVEL ESTIMATED IN THE TANK
PARAMETER
DEFINITIONThis parameter is used to estimate the percentage of alcohol contained in the petrol in
the main tank.
NOTESThere must be no present or stored faults.
Refer to CLIO III or MODUS Wiring Diagram Technical Note.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
This percentage must be between:
0 < PR743 < 100%
This parameter allows the computer to estimate the alcohol level contained in the petrol.
Status ET671 Alcohol level programming should be COMPLETED. This indicates that the percentage of alcohol
in the tank has been detected.
If status ET671 Alcohol level programming is NOT COMPLETED, repeat the programming procedure (see
Configurations and programming, Alcohol level programming).
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections
Using the universal bornier, check the insulation and continuity on the following connections:
●3GH between components 887 and 120.
●3GK between components 887 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the upstream oxygen sensor.
If the fault is still present, contact the Techline.
