NOTE: If three attempts are made to enter
the secure access mode using an incorrect
PIN, secured access mode will be locked out
for one hour. To exit this lockout mode, turn
the ignition to the run position for one hour
then enter the correct PIN. (Ensure all
accessories are turned off. Also monitor the
battery state and connect a battery charger if
necessary).
5. Press ENTER to transfer the secret key (the
SKREEM will send the secret key to the PCM).
3.2.10 PROGRAMMING THE SKREEM
NOTE: If the PCM and the SKREEM 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 SKREEM.
1. Turn the ignition on (transmission in park/
neutral).
2. Use the DRBIII
and select THEFT ALARM,
SKREEM then MISCELLANEOUS.
3. Select SKREEM MODULE REPLACEMENT
(GASOLINE).
4. Program the vehicle four-digit PIN into the
SKREEM.
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 SKREEM, the SKREEM
must be replaced.
6. Select UPDATE VIN (the SKREEM will learn
the VIN from the PCM).
7. Press ENTER to transfer the VIN (the PCM will
send the VIN to the SKREEM).
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
SKREES system.
3.2.11 PROGRAMMING THE IGNITION
KEYS TO THE SKREEM
1. Turn the ignition on (transmission in park/
neutral).
2. Use the DRBIII
and select THEFT ALARM,
SKREEM, then MISCELLANEOUS.
3. Select PROGRAM IGNITION KEYS.
GENERAL INFORMATION
4. Enter secured access mode by entering the vehi-
cle four-digit PIN.
NOTE: A maximum of eight keys can be
learned to each SKREEM AT ONE TIME. Once
a key is learned to a SKREEM 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) - SKREEM is unable to pro-
gram 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 SKREEM mem-
ory.
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
