PROCEDURE:
Before replacing or reprogramming the computer:
– Select command SC003 Save computer data,
– if the following message appears: backup file exists, do you want to overwrite it?:
(this file corresponds to the last save carried out on the tool)
–select YES.
When the backup is complete, replace the computer or reprogram, then proceed to the next step.
After replacing or reprogramming the computer:
– Select command SC001 Write saved data, then follow the instructions given by the diagnostic tool,
– if the VIN has not been entered (see "Computer identification" on the main screen), select VP010 Enter VIN,
When both these commands have finished:
–switch off the ignition and wait 1minute before switching the ignition on again,
– then check the system faults, and clear any stored faults,
– otherwise, deal with faults that are present and clear the faults in the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
End of operation.IMPORTANT
Thermoplunger faults are displayed during reprogramming.
– DF032 Thermoplunger 1 relay control circuit,
– DF033 Thermoplunger 2 relay control circuit,
– DF034 Thermoplunger 3 relay control circuit,
– DF238 Thermoplunger 3 relay circuit,
– DF239 Thermoplunger 2 relay circuit,
– DF240 Thermoplunger 1 relay circuit.
In this case, configure the thermoplungers using configuration CF030 Thermoplungers.
IMPORTANT
– The injection computer retains the immobiliser code for life.
– The system has no security code.
– It is forbidden to perform tests with computers borrowed from the Parts Department or from another vehicle
which must then be returned.
– These computers are hard-coded.
– If the injection computer appears to be faulty, contact the Techline and refer to the fault finding log.

NOTESConditions for applying the fault finding procedure to stored faults:
Only deal with this fault if it is stored.
Special notes:
The supply relay of the injection control unit (50A) is located on a relay plate in the
engine connection unit under the Protection and Switching Unit.
If the fault is present, the level 1 warning light is lit.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Check the Protection and Switching Unit connections (Vdiag 50, 58, 5C only).
Check the injection computer connections.
Repair if necessary.
Check the condition of the battery terminals making sure they are correctly tightened.
Check the condition of the injection supply relay and its mounting.
Check the 5D (5A) + after ignition supply located on the UPC (Protection and Switching Unit) (Vdiag 50, 58, 5C
only).
Repair if necessary.
Check the continuity and absence of interference resistance of connection 3AA between components 120 and
983.
If the connection or connections 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.
If the fault is still present, contact the Techline.
IMPORTANT!WA R N I N G
If the Protection and Switching Unit (Vdiag 50, 58, 5C only) no longer detects the injection
computer signals, GMV 1 will be actuated until the battery is completely discharged.
In the event that engine cooling fan 1 is not working, GMV 2 will be supplied.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
