FAULT FINDING INTRODUCTION
General method
01E
01E-8
–Testing other computers that support fault finding: this test consists of connection and identification of
the computers present on the vehicle which can support fault finding K / L lines.
●New fault finding topics: the fault finding topics are now split into two separate menus:
–Computer diagnosis:
similar to the existing fault finding topics apart from the changed menu presentation.
The states and parameters menus have been modified to allow simultaneous display of these data items
and divided into screens by function and sub-function (example: "ignition" sub-function in Injection).
In addition, the computer fault finding procedure allows access to the vehicle "repair" menu when replacing
parts to be matched with the vehicle (configuration, programming).
–Fault finding by function:
limited to computer fault finding present on the multiplex network of the vehicle
and to the keyless vehicle, air conditioning and tyre functions. This new type of fault finding allows an
overall diagnosis of a function to be made by simultaneous dialogue with all the computers involved in
providing the service. In this way, it is possible to simultaneously analyse all the components associated with
a function and also simultaneously supervise intersystem exchanges between the computers responsible
for a customer service.
Note:
In the event of detecting a faulty component, it is necessary to switch to computer fault finding mode to
perform the configuration operations - programming the replaced part.
If a function fault is detected, a physical part is replaced: hence the choices made concerning
navigation of the diagnostic tool.
