SKIM in the vehicle in order for the system to recognize
them as valid keys. This can be done by the dealer
using a DRBIII scan tool or, if Customer Learn pro-
gramming is an available SKIS feature in the market
where the vehicle was purchased, the customer can pro-
gram the additional keys, as long as at least two valid
Sentry Keys are already available. (Refer to 8 - ELEC-
TRICAL/VEHICLE THEFT SECURITY - STANDARD
PROCEDURE - SENTRY KEY TRANSPONDER PRO-
GRAMMING).
The SKIS performs a self-test each time the igni-
tion switch is turned to the On position, and will
store fault information in the form of Diagnostic
Trouble Codes (DTC's) if a system malfunction is
detected. The SKIS can be diagnosed, and any stored
DTC's can be retrieved using a DRBIII
Refer to the appropriate diagnostic information.

SKIS INDICATOR FAILS TO LIGHT DURING BULB TEST
If the Sentry Key Immobilizer System (SKIS) indi-
cator 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 - ELEC-
TRICAL/INSTRUMENT CLUSTER - DIAGNOSIS
AND TESTING - ACTUATOR TEST). If the SKIS
indicator still fails to light during the bulb test, a

3. Ground circuit faulty.
4. Fused B(+) circuit faulty.
5. Fised ignition switch
output circuit faulty.
1. Invalid key in ignition

fault detected.
DIAGNOSIS AND TESTING - SENTRY KEY
IMMOBILIZER SYSTEM
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRECAU-
TIONS COULD RESULT IN ACCIDENTAL AIRBAG
DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
CORRECTION
1. Test and replace the faulty instrument cluster
or bulb as required.
2. Test and replace the SKIM fused B(+) and
fused ignition switch output (run-start) fuses in the
fuse block as required.
3. Test and repair the SKIM ground circuit as
required.
4. Test and repair the SKIM fused B(+) circuit as
required.
5. Terst and repair the SKIM fused ignition switch
output (run-start) circuit as required.
1. Replace the key with a known valid key.
2. Use a DRBIII scan tool to diagnose the
key-related fault. Refer to the appropriate
diagnostic information.
1. Use a DRBIII scan tool to diagnose the SKIS.
Refer to the appropriate diagnostic information.
rent or ground to the Sentry Key Immobilizer Module
(SKIM) should be suspected, and the following proce-
dure should be used for diagnosis. Refer to the appro-
priate wiring information. The wiring 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 connec-
