VERIFICATION TESTS

Verification Tests
1. Disconnect all jumper wires and reconnect all previously disconnected components and
connectors.
2. If the Sentry Key Immobilizer Module (SKIM) or the Engine Control Module (ECM) was
replaced, proceed to number 5. If the SKIM or ECM was not replaced, continue to the next
number.
3. If the Body Control Module was replaced, turn the ignition on for 15 seconds (to learn VIN).
If the vehicle is equipped with VTSS, use the DRB and enable VTSS.
4. Program tire size, country code and all RKE transmitters (if RKE Module was replaced) and
other options as necessary. Proceed to number 12.
5. Obtain the Vehicle's unique PIN assigned to it's original SKIM from the vehicle's invoice.
6. NOTE: Once Secured Access Mode is active, the SKIM will remain in that mode for 60
seconds.
7. With the DRB, select THEFT ALARM, SKIM, MISCELLANEOUS and select SKIM
REPLACED. Enter the 4 digit PIN to put the SKIM in Secured Access Mode.
8. The DRB will prompt for the following steps.
9. Using the DRB, program all customer keys into the SKIM memory. This requires that the
SKIM be in Secured Access Mode, using the 4 digit PIN.
10. Note: If the ECM is replaced, the VIN and the unique Secret Key data must be transferred
from the SKIM to the ECM. This procedure requires the SKIM to be placed in Secured Access
Mode using the 4-digit PIN.
11. Note: If 3 attempts are made to enter Secured Access Mode using an incorrect PIN, Secured
Access Mode will be locked out for 1 hour which causes the DRB to display Bus +\- Signals
Open . To exit this mode, turn ignition to Run for 1 hour.
12. Ensure all accessories are turned off and the battery is fully charged.
