6.7.2 Basic diagnostic process - Fault reading
LEXIA3 also enables you to list all the faults detected, computer by computer, and to
carry out various tests and checks relating to the faults detected.
A fault is the result of a failure of a computer, a wiring harness or a sensor, etc.
1. Start by running the General Test on the vehicle concerned (see Section 6.7.1).
2. Then select the defective computer type (the BSI in the example above), and
confirm.
3. Read the faults. The list of errors detected on the computer is then displayed.
6.7.3 Basic diagnostic process - Related contexts
To identify the context in which a particular fault occurs, LEXIA3 allows you to display
the related variables recorded by the computer when the fault occurred (for example,
mileage at which fault occurred, speed, temperature, etc.).
1. Start by reading the faults on the system concerned (see Section 6.7.2).
2. Select the fault for which you want details of the occurrence context and confirm.
