Cancelling the error
When the frequency counter reaches the value 0, the error is cancelled and so are the parameters associ­
ated with it.
The immediate cancelling of the entire errors memory takes place in the following cases:
- by means of the "cancel errors memory" command sent by the tester;
- by interrupting the supply to the injectors control unit (disconnecting the battery or the connector for
the control unit).
Fault diagnosis with the Fiat/Lancia Tester
On the right hand side of the engine compartment (near the engine oil dip stick) is the diagnostic socket
to which the Fiat/Lancia Tester is connected.
The exchange of data between the control unit and the Tester takes place via a two direction serial line
(line K) using the standard Bosch communication protocol.
The Tester can supply the following information:
- display of the errors;
- display of engine parameters;
- active diagnosis.
