Initial Inspection - Instrument Cluster

NOTE: If the bi-fuel vehicle does not operate correctly in alternative fuel mode, refer to Powertrain Management.

1. Verify the customer concern by operating the system. If the concern is with the fuel gauge, determine if the fuel gauge is operating correctly with the ignition switch:
1 in the RUN position with the engine OFF
2 in the START position before the ignition switch is released
3 in the RUN position with the engine

2. Visually inspect for obvious signs of mechanical or electrical damage.

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 is not visually evident, connect the scan tool to the data link connector located beneath the instrument panel and select the vehicle to be tested from the scan tool menu. If the scan tool does not communicate with the vehicle:
5. check that the program card is correctly installed check the connections to the vehicle check the ignition switch position
6. If the scan tool still does not communicate with the vehicle, refer to the scan tool manual.
7. Carry out the DATA LINK DIAGNOSTIC TEST. If the scan tool responds with:
8. CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, For additional information, refer to Module Communications Network (Information Bus).
^ NO RESP/NOT EQUIP for alternative fuel control module (AFCM), GO to Pinpoint Test A. Test A: No Warning Indicators/Gauge Function
^ SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs). Erase the continuous DTCs and carry out self-test diagnostics for the instrument cluster.

9. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics. Diagnosis By Symptom - Instrument Cluster
