DESCRIPTION AND OPERATION (Continued)
AMBIENT TEMPERATURE
The temperature is displayed in whole degrees Cel-
sius or Fahrenheit. Temperatures greater than or
equal to zero are displayed unsigned and tempera-
tures below zero are displayed signed (-). If the tem-
perature is more
temperature sending line is shorted to ground, the
compass and ambient temperature screen will dis-
play SC. If the temperature is less than -40°C (-40°F)
or the temperature sending line is an open circuit,
the compass and ambient temperature screen will
OC. If the message CCD bus to display the ambient
temperature. Refer to the proper Body Diagnostic
Procedures manual.
MINI TRIP COMPUTER MESSAGES
The Mini Trip Computer data is obtained from
information put on the CCD bus from thee Power-
train Control Module and the Body Control Module.
The CMTC will not display information for any of the
screens for which it did not receive the proper data
over the CCD bus for that particular screen. In
which case the message CCd will be displayed. If the
CCd message is displayed on all the screens of the
CCD bus with a scan tool (DRB). If some of the
screens appear to be functioning properly but some of
the screens display CCd then check either the Pow-
ertrain Control Module or the Body Control Module
for proper CCD bus communications. If the CCd mes-
sage still persist refer to the Mini Trip Computer Self
Diagnostic Test.
DATA LINK CONNECTOR
Data link connector is located on the left side kick
panel just above hood release.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURE
In order to diagnose the instrument cluster func-
tion, a DRB scan tool and the proper Body Diagnostic
Procedures Manual are required.
As a quick diagnosis, the cluster will perform a
function check immediately after the ignition is
switched to the RUN/START position. The electronic
display, odometer and transmission range indicator
and all warning lamps except:
• Cruise
• Fog lamps
• High beam
• Low fuel
• Turn signal
will illuminate for a brief period.
If the cluster is not receiving CCD bus messages,
the cluster will appear nonfunctional except for the
than 55°C (131°F)
INSTRUMENT PANEL AND SYSTEMS
continuously illuminated airbag indicator and NO
BUS message displayed.
If the cluster is not receiving CCD bus messages,
refer to the pre-diagnostic test described in proper
Body Diagnostic Procedures Manual or refer to the
or the Instrument Cluster Self-Diagnostic Test below.
INSTRUMENT CLUSTER SELF- DIAGNOSTICS
Initiate
depressing the odometer/trip reset button while turn-
ing the ignition key to the OFF/RUN/START posi-
tion. This will cycle an electronic display segment
check and illumination in sequence of all CCD bus
activated cluster warning indicators. There are four
Check (CHEC) functions:
(1) CHEC 1, checks the gauges.
(2) CHEC 2, checks the warning lamps.
(3) CHEC 3, checks the odometer/trip meter.
(4) CHEC 4, Transmission Range Indicator for the
automatic transmission or the autostick transmis-
sion.
If the diagnostic procedure determines that a
replacement of an instrument cluster component is
required, refer to the proper component removal pro-
cedure.

(1) If all gauges fail to move, replace Cluster
Printed Circuit (PC) Board.
(2) If any gauge fails to move, replace the gauge
assembly.
(3) If any gauge(s) is not in the proper position,
replace Cluster Printed Circuit Board.
