SECURITY INDICATOR FAILS TO LIGHT DURING BULB TEST
If the security indicator in the instrument cluster
fails to illuminate for about three seconds after the
ignition switch is turned to the On position (bulb
test), perform the instrument cluster actuator test.
(Refer to 8 - ELECTRICAL/INSTRUMENT CLUS-
TER - DIAGNOSIS AND TESTING - ACTUATOR
TEST). If the security indicator still fails to light dur-
ing the bulb test, a wiring problem resulting in the
loss of battery current or ground to the Sentry Key
Immobilizer Module (SKIM) should be suspected, and
the following procedure should be used for diagnosis.
Refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
NOTE: The following tests may not prove conclu-
sive in the diagnosis of this system. The most reli-
able, efficient, and accurate means to diagnose the
Sentry Key Immobilizer System requires the use of
a DRBIII scan tool. Refer to the appropriate diag-
nostic information.
SENTRY KEY IMMOBILIZER SYSTEM DIAGNOSIS
POSSIBLE CAUSES
1. Light-Emitting Diode (LED)
faulty.
2. Fuse faulty.
3. Ground path faulty.
4. Battery feed faulty.
5. Ignition feed faulty.
1. Invalid key in ignition
switch lock cylinder.
2. Key-related fault.
1. SKIS system malfunction/
fault detected.
2. SKIS system inoperative.
VEHICLE THEFT SECURITY
CORRECTION
1. Perform the instrument cluster actuator test.
(Refer to 8 - ELECTRICAL/INSTRUMENT
CLUSTER - DIAGNOSIS AND TESTING -
ACTUATOR TEST)..
2. Check the SKIM fused B(+) fuse and the fused
ignition switch output (run-start) fuse in the JB.
Replace fuses, if required.
3. Check for continuity to ground at the connector
for the SKIM. Repair wiring, if required.
4. Check for battery current at the connector for
the SKIM. Repair wiring, if required.
5. Check for battery current at the connector for
the SKIM with the ignition switch in the On
position. Repair wiring, if required.
1. Replace the key with a known valid key.
2. Use a DRBIII scan tool and the appropriate
diagnostic information for further diagnosis.
1. Use a DRBIII scan tool and the appropriate
diagnostic information for further diagnosis.
2. Use a DRBIII scan tool and the appropriate
diagnostic information for further diagnosis.
(1) Check the fused B(+) fuse (Fuse 1 - 15 ampere)
in the Junction Block (JB). If OK, go to Step 2. If not
OK, repair the shorted circuit or component as
required and replace the faulty fuse.
(2) Check for battery voltage at the fused B(+) fuse
(Fuse 1 - 15 ampere) in the JB. If OK, go to Step 3. If
not OK, repair the open B(+) circuit between the JB
fuse and the Power Distribution Center (PDC) as
required.
(3) Check the fused ignition switch output (run-
start) fuse (Fuse 10 - 10 ampere) in the JB. If OK, go
to Step 4. If not OK, repair the shorted circuit or
component as required and replace the faulty fuse.
(4) Turn the ignition switch to the On position.
Check for battery voltage at the fused ignition switch
output (run-start) fuse (Fuse 10 - 10 ampere) in the
JB. If OK, go to Step 5. If not OK, repair the open
fused ignition switch output (run-start) circuit
between the JB and the ignition switch as required.
(5) Disconnect and isolate the battery negative
cable. Disconnect the instrument panel wire harness
connector for the Sentry Key Immobilizer Module
(SKIM) from the SKIM connector receptacle. Check
for continuity between the ground circuit cavity of
the instrument panel wire harness connector for the
