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
Ye s®Repair is not complete, refer to the appropriate symptom.

POWERTRAIN VERIFICATION TEST VER - 5 APPLICABILITY
1. NOTE: If the PCM has been replaced and the correct VIN and mileage have not
been programmed, a DTC will be set in the ABS Module, Airbag Module and the
SKIM.
2. NOTE: If the vehicle is equipped with a Sentry Key Immobilizer System, Secret
Key data must be updated. Refer to the Service Information for the PCM, SKIM and
the Transponder (ignition key) for programming information.
3. Inspect the vehicle to ensure that all engine components are properly installed and
connected. Reassemble and reconnect components as necessary.
4. Connect the DRBIIItto the data link connector.
5. Ensure the fuel tank has at least a quarter tank of fuel. Turn off all accessories.
6. If a Comprehensive Component DTC was repaired, perform steps5-8.IfaMajor OBDII
Monitor DTC was repaired skip those steps and continue verification.
7. After the ignition has been off for at least 10 seconds, restart the vehicle and run 2 minutes.
8. If the Good Trip counter changed to one or more and there are no new DTC's, the repair was
successful and is now complete. Erase DTC's and disconnect the DRBIIIt.
9. If the repaired DTC has reset, the repair is not complete. Check for any related TSB's or flash
updates and return to the Symptom list.
10. If another DTC has set, return to the Symptom List and follow the path specified for that
DTC.
11. With the DRBIIIt, monitor the appropriate pre-test enabling conditions until all conditions
have been met. Once the conditions have been met, switch screen to the appropriate OBDII
monitor, (Audible beeps when the monitor is running).
12. If the monitor ran, and the Good Trip counter changed to one or more, the repair was
successful and is now complete. Erase DTC's and disconnect the DRBIIIt.
13. If the repaired OBDII trouble code has reset or was seen in the monitor while on the road
test, the repair is not complete. Check for any related technical service bulletins or flash
updates and return to Symptom List.
14. If another DTC has set, return to the Symptom List and follow the path specified for that
DTC.

POWERTRAIN VERIFICATION TEST VER - 6 APPLICABILITY
1. NOTE: If the PCM has been replaced and the correct VIN and mileage have not
been programmed, a DTC will be set in the ABS Module, Airbag Module and the
SKIM.
2. NOTE: If the vehicle is equipped with a Sentry Key Immobilizer System, Secret
Key data must be updated. Refer to the Service Information for the PCM, SKIM and
the Transponder (ignition key) for programming information.
3. Inspect the vehicle to ensure that all engine components are properly installed and
connected. Reassemble and reconnect components as necessary.
4. The LDP Monitor Test Mode has been added to the DRBIII to verify repairs to the LDP
System. A DRB software program was written which causes the PCM to run the LDP Monitor
as part of this test. Test failures will be indicated through a stored DTC.
5. LDP Monitor Test Mode is a useful way to run a total system performance test. Use this test
to verify any type of LDP system repair.
6. Software program makes temporary changes to operating mode of PCM. For this reason, it
is critical that test not be interrupted. PCM's left in this mode as result of interrupted test will
illuminate the MIL for 8-10 mi of driving with no DTC's stored.
7. Erasing DTC's will not change this condition.
8. If a vehicle is found to be stuck in the mode described above, the LDP Dealer Test should be
re-run in its entirety so that the software program in the DRBIII can restore the PCM
operating mode.
9. Note similarity to LDP Monitor screen found under OBDII Monitors. Failure modes are
fewer in this System Test than OBDII LDP Monitor. System Test only stores Small Leak DTC
to indicate problem with system. No other type of failure mode indication given.
10. System Test failure may have been, for example, due to a large leak, but the PCM will set
the Small Leak DTC to indicate failures that occurred as part of the system test.
11. Connect the DRB to the data link connector. Engine running, turn off all accessories.
12. Note: While test is being performed, PCM must see RPM, minimum MAP, No Vehicle speed
and minimum Throttle Position sensor (At idle, in park.) With DRBIII in System Tests, perform
the LDP Monitor Test and follow the instructions on the screen.
13. If the LDP Monitor Test failed and a Small Leak DTC has set, the repair is not complete.
Check for any related Technical Service Bulletins and return to Symptom List.
14. If any other trouble code has set, return to Symptom List and follow the path specified for
that trouble code. If the LDP Monitor Test passed, the repair was successful and testing is now
complete.
Are any DTCs present?All
Ye s®Repair is complete.
No®Repair is not complete, refer to appropriate symptom.
