4 - System reprogramming in case of component replacement
1 Cylinder replacement
- Remove the transponder of the original master key and install it on the master key of the new cylinder.
- Reprogramme the system as described previously.
2 Decoder replacement
Following replacement of the decoder the full programming procedure must be followed.
The programming is indispensable to achieve engine ignition.
(See page 9-18
system programming)
3 Control unit replacement
Following replacement of the control unit it is necessary to carry out the programming in order to activate engine
ignition.
In this case it is sufficient to set to “ON” using the master key.
NOTE
:
- Programming cannot be carried out with a service key (black).
- An unprogrammed control unit allows no functional diagnosis of the engine.
4 Service key replacement or duplication
Keys can be duplicated by using the drafts and the original master key.
It is also possible to request a duplicate by using the code of the vehicle CODE CARD.
Carry out the new programming using the master key and all the service keys (See page 9-18 - system
programming)
NOTE
:
The CODE CARD can only be used when the original MASTER KEY is available.
1 Diagnostic code n°1
Code 1 indicates an unprogrammed system - see page
9-17.
If the code persists after carrying out the programming
procedure, repeat the procedure more carefully, paying
attention to the “ON” timing of each key.
If the code still persists proceed as follows:
- Disconnect the negative battery.
- Remove the connector from the control unit.
- Link the special tool 020481Y between the fuel injec-
tion system and the control unit.
- Remove the main connector from the decoder.
NOTE
: To access the components see page 9-7.
Diagnostic codes
LED signalling is divided into 3 phases:
1st phase - One flash: recognition of the “ON” setting
2nd phase - Series of flashes: diagnostic code signal
3rd phase - Fixed light on or off: on = ignition inhibited,
off = ignition possible
