TEST SK-1AIDENTIFYING SENTRY KEY IMMOBILIZER SYSTEM PROBLEMS
NOTE:The Sentry Key Immobilizer System (SKIS) diagnosis may require usage of the customer's
additional keys to verify the cause of the system failure. In the event that the Sentry Key Immobilizer
Module (SKIM) needs replacing, all of the keys previously programmed into the SKIM's memory
must be programmed into the new SKIM.THEREFORE IT IS IMPORTANT THAT ALL OF THE
CUSTOMER'S KEYS PROGRAMMED FOR THE VEHICLE BE OBTAINED PRIOR TO BEGIN-
NING VEHICLE DIAGNOSIS.
NOTE:It is necessary to obtain the four-digit Personal Identification Number (PIN) from the
customer or the vehicle invoice. The PIN is required to perform certain SKIM tasks using the DRB.
NOTE:It is very important that the ECM/BCM is programmed with the correct Vehicle Identification
Number (VIN). Incorrect VIN programming may result in incorrect diagnosis and unnecessary
component replacement. Use the DRB to verify the correct VIN and country code are programmed
into the SKIM.
1. The battery must be fully charged for any test in this manual.
2. Attempt to start the engine. Crank for up to 10 seconds if necessary.
3. Connect the DRB to the diagnostic connector and select ``Theft Alarm'' then ``SKIM''.
If the DRB displays ``No Response''..................................perform test 1B
NOTE:If the DRB screen is blank or has a DRB error message displayed, go toGeneral
Information Section 3.5in this manual.
4. With the DRB, read and record SKIM trouble codes.
5. If diagnostic trouble code are displayed, refer to the diagnostic trouble code list on the next page
for the appropriate test.
NOTE:For all component locations, seeGeneral Information Section 4.0in this manual.

**These trouble codes indicate an internal SKIM fault. Using the DRB, clear SKIM trouble code(s).
Perform several key cycles, leaving the key on for a minimum of 30 seconds per cycle. Using the
DRB, read SKIM trouble codes. If the trouble code is present, replace the SKIM.
NOTE:An intermittent start and stall condition accompanied with a transponder DTC can be caused
by the presence of a non-programmed key or key programmed to another vehicle, near the SKIM
antenna (ignition halo). This can occur if the customer has a key holder (ring) that contains more
than one key equipped with a transponder chip.
After replacement of the Sentry Key Immobilizer Module (SKIM) seeGeneral Information Section 8.0
for SKIM initialization.
