Removing-refitting

Removing-refitting

1. Pull the locking device (1) upwards and disconnect the top connector (2).
2. Pull the locking device (1) downwards and disconnect the bottom connector (2) then undo the nuts (3).
3. Remove the bracket (1) and move it aside, then remove the fuel injection-ignition electronic control unit (2).

Under no circumstances may fuel injection control units be exchanged between different vehicles to check whether they are working.

During diagnosis, before replacing the control unit, make sure that the component under examination is really not working, as when a new control unit is supplied, the secret code of the Fiat CODE system is memorized, rendering the control unit totally unusable on other cars.

Voltage may be present on unconnected pins, so no connection should be made otherwise there will be the risk of short circuit with damage to the control unit.
The multi-connector should be inserted and withdrawn with the ignition off (key removed).
