2. For diagnosis of the Seat Belt Indicator, refer to Computer System Diagnosis.
3. If the Headlamps ON Chime does not sound with the Headlamp switch in PARK or HEAD, check for an open in circuit 9 between the RH IP

check (Refer to Troubleshooting Procedures).

Check Gauges chime sounds when all gauge pointers are in normal range or fails to chime when pointers are out of normal range and there are no
current DTCs (NOTE: The Check Gauges chime will only sound three times for each indicator that is commanded on. Use the scan tool to monitor
the BFC Serial Peripheral Interface (SPI) serial data link. If the Instrument Cluster is commanding the Check Gauges chime on, and the BFC does
not respond, replace the BFC. If the BFC is commanding the Check Gauges chime OFF and an indicator is ON, replace the Instrument Cluster.
