Cancelling the error

When the frequency counter reaches 0, the fault and the parameters associated with it are cancelled.
The immediate cancellation of the entire errors memory takes place through the "cancelling errors memory"
command sent by the diagnostic equipment.

Connection with the diagnostic equipment

The diagnostic socket to which the diagnostic equipment (Examiner or SDC) is connected is located at
the front right of the engine compartment (see diagram on page 18).
The exchange of data between the control unit and the diagnostic equipment takes place via a two-way
serial line (line K) using the standard Bosch communication protocol.
The diagnostic equipment can provide the following information:
- display of the engine parameters;
- display of the errors;
- active diagnosis.
