each in 2nd and 3rd gear between each kickdown.
7. For a specific DTC, drive the vehicle to the Symptom's When Monitored/When Set conditions
to verify the DTC repair.
8. Check for Diagnostic Trouble Codes (DTC's) during the road test. If a DTC sets during the
road test , return to the Symptom list and follow the path.

VERIFICATION TESTS

BODY VERIFICATION TEST - VER 1 APPLICABILITY
1. Disconnect all jumper wires and reconnect all previously disconnected components and
connectors.
2. With the DRBIIIt, record and erase all DTCs from ALL modules. Cycle the ignition on then
off
3. If the Sentry Key Immobilizer Module (SKIM) or the Powertrain Control Module (PCM) was
replaced, proceed to number 7. If the SKIM or PCM was not replaced, continue to the next
number.
4. If the Body Control Module was replaced, turn the ignition on for 15 seconds (to allow the
new BCM to learn VIN) or engine may not start (if VTSS equipped). If the vehicle is equipped
with VTSS, use the DRBIIItand enable VTSS.
5. Program all other options as needed.
6. If any repairs were made to the HVAC System, disconnect the battery or, using the DRBIIIt,
recalibrate the HVAC doors. Proceed to number 14.
7. Obtain the Vehicle's unique PIN assigned to it's original SKIM from either the vehicle's
invoice or from Chrysler's Customer Assistance Center (1-800-992-1997).
8. NOTE: Once Secured Access Mode is active, the SKIM will remain in that mode for 60
seconds.
9. With the DRBIIIt, select THEFT ALARM, SKIM, MISCELLANEOUS and select SKIM
REPLACED. Enter the 4 digit PIN to put the SKIM in Secured Access Mode.
10. The DRBIIItwill prompt for the following steps. (1) Program the country code into the
SKIM's memory. (2) Program the vehicle's VIN into the SKIM memory. (3) Transfer the
vehicle's Secret Key data from the PCM.
11. Using the DRBIIIt, program all customer keys into the SKIM memory. This requires that
the SKIM be in Secured Access Mode, using the 4 digit PIN.
12. Note: If the PCM is replaced, the VIN and the unique Secret Key data must be transferred
from the SKIM to the PCM. This procedure requires the SKIM to be placed in Secured Access
Mode using the 4-digit PIN.
13. 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 DRBIIItto display9Bus +\- Signals
Open9. To exit this mode, turn ignition to Run for 1 hour.
14. Ensure that all accessories are turned off and the battery is fully charged.
15. Start and run the engine for 2 minutes. Operate all functions of the system that caused the
original concern.
16. Turn the ignition off and wait 5 seconds. Turn the ignition on and using the DRBIIIt, read
DTCs from ALL modules.
Are any DTC's present or is the original condition still present?All
