When the data link has been established, you
can then select the required troubleshooting
functions provided. The functions represent
program sequences within On Board Diagnostic
(OBD). Their application is described in the
appropriate sections of this repair manual. After
first checking the control module version, start
the troubleshooting procedure with "Check DTC
Memory" function 02.
Any DTCs which may be stored in DTC memory
will be indicated on the display of the scan tool.
Diagnostic information leads via DTC tables to
possible causes and specific repair procedures.
DTC tables are located in the appropriate
sections of this repair manual.
The OBD distinguishes between "static" and
"sporadic" malfunctions. If a malfunction which
has been stored as "static" is no longer present
when the ignition is switched on, it is converted
to "sporadic".
Sporadically occurring malfunctions are indicated
as such. "/SP" will appear at right on the tester
display.
A sporadic malfunction is erased automatically if
it no longer occurs after a certain number of
driving cycles.
