Electrical equipment
Control module
55.
The vehicle is fitted with numerous electronic
control units which have autodiagnostic func
tions.
When these control units are connected to di
agnostic equipment (Examiner or other in
struments) it is possible to read the autodiag
nostic information (parameters, errors) or carry
out active diagnosis.
On the version with EOBD (European On
Board Diagnosis) which conforms to Directive
98/69/CE (EURO 3), there is not an indi
vidual diagnostic socket for each control
unit, but a single.- standardized 16-way
diagnostic socket, on the left hand side of
the dashboard, under the junction unit.
The diagnostic equipment (Examiner or other instruments) is connected to it using a special adaptor
known as "MPX 97". Using this adapator it is possible to select the system the autodiagnosis is going to
be carried out on.
