VERIFICATION TESTS
BODY VERIFICATION TEST - VER 1
APPLICABILITY
1. Disconnect all jumper wires and reconnect all previously disconnected components and
connectors.
2. If the Sentry Key Immobilizer Module (SKIM) or the Powertrain Control Module (PCM) were
replaced, proceed to number 4. If the SKIM or PCM were not replaced, continue to the next
number.
3. If the Remote Keyless Entry module was replaced, using the DRBIII
t select 9Theft Alarm9
9VTSS9 9Miscellaneous9 and 9Program RKE9. Program all transmitters used with this vehicle.
Proceed to number 11.
4. Obtain the Vehicle’s unique PIN number assigned to it’s original SKIM module from either
the vehicle’s invoice or from Chrysler’s Customer Center (1-800-992-1997).
5. With the DRBIII, select THEFT ALARM, SKIM, MISCELLANEOUS and select
9Skim
Module Replaced
9 function. Enter the 4 digit PIN number to put SKIM in 9Access Mode9.
6. The DRBIII will prompt you through the following steps. (1) Program the country code into
the SKIM’s memory. (2) Program the vehicle’s VIN number into the SKIM’s memory. (3)
Transfer the vehicle’s Secret Key data from the PCM.
7. Once secured access mode is active, the SKIM will remain in that mode for 60 seconds.
8. Using the DRBIII, program all customer keys into the SKIM’s memory. This requires that
the SKIM be in secured access mode, using the 4 digit code.
9. Note: If the PCM is replaced, 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 code.
10. 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 III to display
9Bus +\- Signals
Open
9. To exit this mode, turn ignition to the 9Run9 pos. for 1 hour.
11. Ensure all accessories are turned off and the battery is fully charged.
12. Ensure that the Ignition is on, and with the DRBIII
t, erase all Diagnostic Trouble Codes
from ALL modules. Start the engine and allow it to run for 2 minutes and fully operate the
system that was malfunctioning.
13. Turn the ignition off and wait 5 seconds. Turn the ignition on and using the DRBIII
t, read
DTC’s from ALL modules.
14. If ANY codes are present, select the appropriate symptom from the Symptom List and
continue diagnostics. If NO codes are present and the customers complaint cannot be
duplicated, the repair is complete.
All
POWERTRAIN VERIFICATION TEST VER - 1
APPLICABILITY
1. Inspect the vehicle to ensure that all engine components are properly installed and
connected. Reassemble and reconnect components as necessary.
2. Inspect the engine oil for contamination. If it is contaminated, change the oil and filter.
3. Perform the steps 4 through 6 if the PCM has been replaced. Then proceed with the
