Removing

It is absolutely prohibited to swap control units between different cars to check their efficiency.
During testing, before replacing a control unit, check that the component is really inefficient because when a new control unit is activated, the Fiat CODE system secret code is stored and this makes the control unit completely unusable on other cars.

Unconnected pins may be live and should not be connected due to the risk of short-circuits which could damage the control unit.
Fit and remove multiple connectors with the key out.

Removing

Take out the ignition key and disconnect the battery leads;

1. Disconnect connectors A and B by moving cursors in the arrowed direction.
2. Unscrew the retaining bolts indicated and take off brackets (1) and (2), then remove the injection-ignition contoro unit from the car.

Refitting

Carry out removal instructions in reverse order. Take care not to force the connectors onto the control unit.
