NOTE
If vehicle is equipped with more than one computer module (for example a powertrain control
module [PCM] and a transmission control module [TCM]), the code reader identifies them by their
identification names (ID) assigned by manufacturer (i.e. Engine or Module $A4).
A screen with prompted information to erase the previously stored data in order to save the data
from this test displays as below.
Figure 4-2 Sample Erase the Previous Stored Data Screen
If previous data is to be erased, select
Yes

UP/DOWN

pick No. Wait a few seconds to return to Diagnostic Menu.
NOTE
If no data is stored in the code reader, the above screen will not show up.

Diagnostic
trouble
codes
stored
in
a
control
module
are
used
to
help
identify
the
cause
of
a
trouble
or
troubles
with
a
vehicle.
These
codes
have
occurred
a
specific
number
of
times
and
indicate
a
problem
that
requires
repair.
Pending
codes
are
referred
to
as
maturing
codes
that
indicate
intermittent
faults.
If
the
fault
does
not
occur
within
a
certain
number
of
drive
cycles
(depending
on
vehicle),
the
code
clears
from
memory.
If
a
fault
occurs
a
specific
number
of
times,
the
code
matures
into
a
DTC
and
the
MIL
illuminates
or
blinks.
There
are
two
ways
to
read
codes
using
