GENERAL INFORMATION
NOTE: If three attempts are made to enter
the secure access mode using an incorrect
PIN, secured access mode will be locked out

3.2.10 PROGRAMMING THE SENTRY KEY
IMMOBILIZER MODULE
NOTE: If the PCM and the SKIM are replaced
at the same time, program the VIN into the
PCM first. All vehicle keys will then need to
be replaced and programmed to the new
SKIM.
1. Turn the ignition on (transmission in park/
neutral).
2. Use the DRBIII and select THEFT ALARM,
SKIM then MISCELLANEOUS.
3. Select SKIM MODULE REPLACEMENT (GAS-
OLINE).
4. Program the vehicle four-digit PIN into the
SKIM.
5. Select COUNTRY CODE and enter the correct
country.
NOTE: Be sure to enter the correct country
code. If the incorrect country code is
programmed into SKIM, the SKIM must be
replaced.
6. Select UPDATE VIN (the SKIM will learn the
VIN from the PCM).
7. Press ENTER to transfer the VIN (the PCM will
send the VIN to the SKIM).
8. The DRBIII will ask if you want to transfer the
secret key. Select ENTER to transfer secret key
from the PCM. This will ensure the current
vehicle ignition keys will still operate the SKIS
system.
3.2.11 PROGRAMMING THE IGNITION
KEYS TO THE SENTRY KEY

learned to each SKIM AT ONE TIME. Once a
key is learned to a SKIM it (the key) cannot be
transferred to another vehicle.
If ignition key programming is unsuccessful, the
DRBIII will display one of the following messages:
Programming Not Attempted - The DRBIII
attempts to read the programmed key status and
there are no keys programmed in the SKIM mem-
ory.
Programming Key Failed - (Possible Used Key
From Wrong Vehicle) - SKIM is unable to program
key due to one of the following:
– faulty ignition key transponder
– ignition key is programmed to another vehicle.
8 Keys Already Learned, Programming Not
Done - SKIM transponder ID memory is full.
1. Obtain ignition keys to be programmed from
customer (8 keys maximum)
2. Using the DRBIII , erase all ignition keys by
selecting MISCELLANEOUS and ERASE ALL
CURRENT IGN. KEYS
3. Program all ignition keys.
Learned Key In Ignition - Ignition key transpon-
der ID is currently programmed in SKIM memory.
3.3 DIAGNOSTIC TROUBLE CODES
Each diagnostic trouble code is diagnosed by
following a specific testing procedure. The diagnos-
tic test procedures contain step-by-step instructions
for determining the cause of trouble codes as well as
no trouble code problems. It is not necessary to
perform all of the tests in this book to diagnose an
individual code.
Always begin by reading the diagnostic trouble
codes using the DRBIII .
3.3.1 HARD CODE
A diagnostic trouble code that comes back within
one cycle of the ignition key is a hard code. This
means that the defect is there every time the
powertrain control module checks that circuit or
function. Procedures in this manual verify if the
DTC is a hard code at the beginning of each test.
When it is not a hard code, an intermittent test
must be performed.
DTC's that are for OBDII/Euro Stage III OBD
monitors will not set with just the ignition key on.
Comparing these to non-emission DTC's, they will
seem like an intermittent. These DTC's require a
set of parameters to be performed (The DRBIII
