Deleting errors
When the frequency counter reaches 0, the fault and associated parameters are deleted.
The entire error memory is cleared immediately in the following cases:
- by means of a "clear error memory" command sent by the tester;
- by interrupting ECU supply (by disconnecting the battery or ECU connector).
Diagnosis using Fiat/Lancia tester
Connect the Fiat/Lancia Tester (F.LT.) to a socket beside the ECU.
Information is exchanged between ECU and Tester via a two-way serial line (line K) using standard
Bosch communication Protocol.
The Tester is able to perform the following functions:
- Error display;
- Engine parameter display;
- Active diagnosis
