E8010 Diagnostics multiple connector

Description

The car is equipped with numerous self-diagnostic electronic control units.

When a tester (Examiner or other instrument) is connected to the control units, self-diagnostic data can be read (parameters, errors) or active testing can be carried out.

This car is not fitted with a specific tester connection for each control unit. Instead, a single standard 16-way tester connection is located on the left hand side of the facia, above the junction unit.

The diagnostic equipment (Examiner or other instruments) is connected to it using a special adaptor called "MPX 97". This adaptor makes it possible to select the system to which you wish to connect.
