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 DRB 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 DRB 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
IMMOBILIZER MODULE
1. Turn the ignition on (transmission in park/
neutral).
2. Use the DRB and select THEFT ALARM, SKIM
then MISCELLANEOUS.
3. Select PROGRAM IGNITION KEYS.
4. Enter secured access mode by entering the vehi-
cle four-digit PIN.
NOTE: A maximum of eight keys can be learned
to each SKIM. Once a key is learned to a SKIM it
(the key) cannot be transferred to another vehicle.
If ignition key programming is unsuccessful, the
DRB will display one of the following messages:
Programming Not Attempted
The DRB attempts to read the programmed key
status and there are no keys programmed in the
SKIM memory.
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
GENERAL INFORMATION
– 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 DRB, erase all ignition keys by select-
ing MISCELLANEOUS and ERASE ALL CUR-
RENT IGN. KEYS
3. Program all ignition keys.
Learned Key In Ignition
Ignition key transponder ID is currently pro-
grammed 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 (See Section 1.0).
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
trouble code is a hard code at a the beginning of
each test. When it is not a hard code, an intermit-
tent test must be performed.
Codes that are for Euro Stage III OBD monitors will
not set with just the ignition key on. Comparing these
to non-emission codes, they will seem like an intermit-
tent. These codes require a set of parameters to be
performed (The DRBIII
with this for MONITOR codes), this is called a "TRIP".
All Euro Stage III OBD DTCs will be set after one or in
some cases two trip failures, and the MIL will be
turned on. These codes require three successful (no
failures) TRIPS to extinguish the MIL, followed by 40
warm-up cycles to erase the code. For further expla-
nation of TRIPS, Pre-test screens, Warm-up cycles,
and the use of a the DRBIII , refer to the On Board
Diagnostic training booklet #81-699-97094.
3.3.2 INTERMITTENT CODE
A diagnostic trouble code that is not there every
time the PCM checks the circuit is an intermittent
code. Most intermittent codes are caused by wiring
or connector problems. Defects that come and go
like this are the most difficult to diagnose; they
must be looked for under specific conditions that
