DESCRIPTION
The vehicle is equipped with many electronic control units with a self-diagnosis function. When a diagnosis equipment (Examiner or other device) is connected to these control units, self-diagnosis data can be read (parameters, errors) or the available active diagnosis tests can be carried out.
All the diagnosis lines flow into the EOBD connector (European On Board Diagnosis) which conforms with Directive 98/69/EC (EURO 3) - ISO standard J1962 - located under the dashboard to the left of the Body Computer.
Via the same connector it is possible to diagnose all the nodes (control units) connected to the low speed B-CAN and the high-speed C-CAN dynamic control network.
See E1050 CAN CONNECTION LINES
There are also individual diagnosis K lines that control individual control units: on this version this involves the electronics for the gas discharge headlights.
In LPG versions, a special diagnosis connector next to the control unit allows the LPG control unit self-diagnosis data to be read.
