Description - DIAGNOSTIC MULTIPLE CONNECTOR - Fiat DOBLO 1.9 JTD 8V da 12/03
The car is equipped with numerous self-diagnostic electronic control units.When diagnostic equipment is connected to these control units, self-diagnostic data can be read (parameters, errors) or active testing can be carried out.This vehicle is not fitted with a diagnostic socket for each control unit, but the entire system is managed by the body computer and the single diagnostic socket is a connector at the actual body computer.One of the functions of the body computer is to control the operation of all the components in the vehicle, ensuring that they are working perfectly and memorizing any possible errors and/or malfunctions.
