CONDITION
POSSIBLE CAUSES
CORRECTION
NO KEY-IN IGNITION
WARNING CHIME, BUT
OTHER CHIME FEATURES OK
1. Driver door ajar switch sense
circuit open.
1. Check for continuity between the driver
door ajar switch sense circuit connector and
the instrument cluster connector. Repair the
open driver door ajar switch sense circuit, if
required.
2. Key-in ignition switch sense
circuit open.
2. Check for continuity between the key-in
ignition switch sense circuit connector and
instrument cluster connector. Repair the
open key-in ignition switch sense circuit, if
required.
3. Key-in ignition switch ground
circuit open.
3. Check for continuity between the ground
circuit cavity of the ignition switch connector
and a good ground. Repair the open ground
circuit, if required.
4. Faulty ignition switch.
4. Check for continuity between the ground
circuit terminal and the key-in ignition switch
sense circuit terminal in the ignition switch
connector. There should be continuity with a
key in the ignition lock cylinder. Replace the
faulty ignition switch, if required.
NO EXTERIOR LAMPS-ON
WARNING CHIME, BUT
OTHER CHIME FEATURES OK
1. Driver door ajar switch sense
circuit open.
1. Check for continuity between the driver
door ajar switch sense circuit connector and
the instrument cluster connector. Repair the
open driver door ajar switch sense circuit, if
required.
2. Headlamp switch signal
circuit open.
2. Check for continuity between the
headlamp switch output circuit connector
and the instrument cluster connector. Repair
the open headlamp switch signal circuit, if
required.
NO CHIMES AND OTHER
INSTRUMENT CLUSTER
FEATURES ERRATIC OR
DISABLED
1. Instrument cluster ground
circuit(s) open.
1. Check for continuity between the ground
circuits of the instrument cluster connector
and a good ground. Repair the open ground
circuits(s), if required.
2. Instrument cluster fused B(+)
circuit(s) open.
2. Check for battery voltage at the B(+)
circuits of the instrument cluster connector.
Repair the open fused B(+) circuit(s), if
required.
3. Instrument cluster fused
ignition switch output (run-start)
circuit open.
3. With the ignition switch in the On
position, check for battery voltage at the
fused ignition switch output (run-start) circuit
of the instrument cluster connector. Repair
the open fused ignition switch output
(run-start) circuit, if required.
4. Faulty instrument cluster.
4. Replace the faulty instrument cluster, if
required.
