3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible)
before proceeding to the next step.
4. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the
diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
zcheck that the program card is correctly installed.
z check the connections to the vehicle.
z check the ignition switch position.
5. If the diagnostic tool still does not power up, refer to the diagnostic tool operating manual.
6. Carry out the DATA LINK DIAGNOSTICS test. If the diagnostic tool responds with: zCKT914, CKT915 OR CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418 -
00 .
z NO RESP/NOT EQUIP for the instrument cluster, Go To Pinpoint Test A or for the
generic electronic module (GEM), Go To Pinpoint Test W .
z SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs),
erase the continuous DTCs and carry out the self- test diagnostics for the instrument
cluster or the GEM.
7. If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index or the GEM Diagnostic Trouble Code Index to continue diagnostics.
8. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.
Instrument Cluster Self- Diagnostic Mode
To enter the instrument cluster self- diagnostic mode, press and hold the instrument cluster
SELECT/RESET button, turn the ignition switch to the RUN position, and then continue pressing the
SELECT/RESET button (five seconds) until tESt is displayed in the odometer. The SELECT/RESET
button must be released within three seconds of the odometer tESt display to begin the self- diagnostic
mode. Press the SELECT/RESET button to advance through the following steps until dtc is displayed.
Depressing the SELECT/RESET button will display any stored continuous DTCs before proceeding to
the next step. z

Odometer
Display Description
GAGE Activates gauge sweep of all gauges, then displays present gauge values. Also
carries out the checksum tests on ROM and EE. All segments
illuminated Illuminates all odometer segments.
bulb Illuminates all micro-controlled indicators and LEDs. Install a new indicator or LED as
necessary. r Returns to normal operation of all micro-
controlled indicators and LEDs and displays
hexadecimal value for ROM level (used when requesting assistance from the hotline). EE Displays hexadecimal value for EE level (used when requesting assistance from the
hotline). dt Displays hexadecimal coding of final manufacturing test date (used when requesting
assistance from the hotline). dtc Displays continuous DTCs in hexadecimal format. Pressing the SELECT/RESET
button will display any DTCs stored before proceeding to the next step. enG Displays the English speed in mph. Speedometer will indicate present speed within
tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0. m Displays the metric speed data (km/h). Speedometer will indicate present speed
within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0. tAc Displays the tachometer data received from the PCM via the SCP network within
tolerances. Tachometer will indicate present rpm. Display will show 0 if input is not received, if input received is invalid for one second or more, or if engine rpm is 0. FUEL Displays the code (0-255) for the fuel sender input to the instrument cluster. The fuel
gauge will display a filtered fuel level value. This filter will keep the pointer from moving suddenly or erratically.
z255 = open send +/- 0
z 232 = full stop +/- 0
z 215 = full mark +/- 10
z 178 = 3/4 mark +/- 8
z 138 = 1/2 mark +/- 7
z 93 = 1/4 mark +/- 5
z 41 = E mark +/- 4
z 54=LOW FUEL (0- 59)
z 0-18=short (0- 20 max) OIL Displays the code (0-
250) for the oil pressure switch input to the instrument cluster.
Oil pressure gauge will indicate present oil pressure. Normal oil pressure (greater
than 6 psi) will display a value between 000 and 176. A low oil pressure or an
inoperative engine oil pressure switch (less than 6 psi) will display a value greater
than 176. dEGC Display of engine temperature in degrees C input from cylinder head temperature
sensor.
z 49 C = "C" mark
z 60 C = normal band start
z 120 C = normal band end
z -40 C = no SCP message for 5 seconds bAtt Displays the code (0-255) for the battery voltage input to the instrument cluster.
Battery voltage gauge will indicate present battery voltage. Klj . 6 ba
