Description - DIAGNOSTIC MULTIPLE CONNECTOR - Fiat STILO 1.4 16v da 07/02 a 06/03
The car is fitted with numerous electronic control units that perform a self-diagnostic function.When a diagnostic tester (Examiner or other device) is connected to these control units, self-diagnosis data can be read (parameters, errors) or the available active diagnostic tests can be carried out.All the diagnostic lines flow into the EOBD connector (European On Board Diagnosis) which conforms with Directive 98/69/CE (EURO 3) - ISO standard J1962 in the Body Computer connector G.Nodes connected to the network are diagnosed via the B-CAN network, while the dynamic car control network is diagnosed by a specific K lines.
