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.

If the fault is still present, carry out the following checks:
The inlet line must be perfectly sealed, from the throttle valve to the cylinder head.
Check:
–the condition of the air filter,
–that the air inlet circuit is not blocked,
–the sealing between the throttle valve and inlet manifold,
–the manifold pressure sensor sealing,
–the fuel vapour absorber bleed, which must not be jammed open,
–the fuel vapour absorber bleed system sealing,
–the brake servo system sealing,
–the cylinder head oil vapour recovery system sealing,
–the sealing between the inlet manifold and cylinder head,
–the exhaust pipe sealing between the cylinder head and catalytic converter.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair:
- If the fault is present, continue to deal with the fault.
- If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.
