3.1.7.2 STORED CODES
Airbag codes are automatically stored in the
ACM’s memory as soon as the malfunction is de-
tected. A ‘‘stored’’ code indicates there was an active
code present at some time. However, the code cur-
rently may not be present as an active code, al-
though another active code could be.
When a trouble code occurs, the airbag warning
lamp illuminates for 12 seconds minimum (even if
the problem existed for less than 12 seconds). The
code is stored, along with the time in minutes it was
active, and the number of times the ignition has
been cycled since the problem was last detected.
The minimum time shown for any code will be one
minute, even if the code was actually present for
less than one minute, Thus, the time shown for a
code that was present for two minutes 13 seconds,
for example, would be three minutes.
When and if the malfunction ceases to exist, an
ignition cycle count will be initiated for that code. If
the ignition cycle count reaches 100 without a
reoccurrence of the same malfunction, the diagnos-
tic trouble code is erased and that ignition cycle
counter is reset to zero. If the malfunction reoccurs
before the count reaches 100, then the ignition cycle
counter will be reset and the diagnostic trouble code
will continue to be a stored code.
If a malfunction is not active while performing a
diagnostic test procedure, the active code diagnostic
test will not locate the source of the problem. In this
case, the stored code can indicate an area to inspect.
WARNING: TO AVOID PERSONAL INJURY OR
DEATH, MAINTAIN A SAFE DISTANCE FROM
ALL AIRBAGS WHILE PERFORMING THE
FOLLOWING INSPECTION:
If no obvious problems are found:
• Erase the stored codes
• Place the ignition in the Run position
• Wiggle the wire harness and connectors
•
Rotate the steering wheel from stop to stop
• Recheck for active codes periodically as you work
through the system.
3.2 AUDIO SYSTEM
The audio system on the 2004 PL consists of a
radio that communicates over the PCI bus. The
speakers are located in the instrument panel, the
front doors and the rear “D” pillars. The instrument
panel speakers are a tweeter type speaker for high
frequency. The front door speakers are a woofer/
midrange type speaker. The rear “D” pillar speakers
are a full range type speaker. If one of the speaker
circuits experiences a short, the other speakers on
that output channel will also shut down until the
circuit is repaired. The radio will also set a trouble
code, which the DRBIII
t
can display.
The in-dash CD-changer is designed to fit into the
existing cubby bin in the center stack. This new
cartridge-less CD-changer is controlled by your ra-
dio, and allows you to individually load up to four
discs at one time. However, due to its compact
design, the CD-changer can only carry out one
operation at a time. For example you can not load a
new disc while playing another at the same time.
Each operation happens sequentially.
The radio unit installed with your system pro-
vides control over all features of the CD-changer
with the exception of the CD load and eject func-
tions, which are controlled by buttons located on the
front of the CD-changer. The radio also supplies the
power, ground, PCI Bus, left and right speaker
output through a single DIN cable. All features you
would expect , such as Disc Up/Down, Track Up/
Down, Random and Scan are controlled by the
radio, which also displays all relevant CD-changer
information on the radio display.
The CD-changer contains a Load/Eject button
and an indicator light for each of the four disc
positions. The individual light indicates whether a
CD is currently loaded in that particular chamber of
the CD-changer. Pressing the individual Load/Eject
button for a particular chamber will eject a disc
currently present in the chamber. If the chamber is
currently empty, actuating the Load/Eject button
will position that chamber to receive and load a new
disc in that chamber.
3.3 COMPASS/TEMPERATURE MIRROR
DESCRIPTION
The optional Compass/Temperature Mirror has a
vacuum fluorescent (VF) display that is integrated
into the rear view mirror. The Compass/Temp Mir-
ror includes the compass/temperature display and
two map/reading lamps. This display provides the
outside temperature and one of eight compass head-
ings to indicate the direction the vehicle is facing.
The Compass/Temp Mirror displays the compass
heading and the outside temperature at the same
time. The Ambient Temperature Sensor monitors
the outside temperature and is hardwired to the
PCM. The Compass/Temp Mirror also receives and
transmits data on the PCI Bus.
OPERATION
The Compass/Temp Mirror incorporates 2 read-
ing lamp buttons with the STEP button and the
Zone/Calibration button features activated by hold-
ing a button for a specified time period. The STEP
button provides the selections between English and
