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 DRBIII

t to 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 steps 5 - 8. If a Major OBDII

DTC.
11. With the DRBIII

t, 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 DRBIII

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.

APPLICABILITY

t to verify repairs to the LDP

System. A DRBIII

t 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

t 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.
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 DRBIII

t 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

t in System Tests,

perform the LDP Monitor Test and follow the instructions on the screen.
13. If the LDP Monitor Test failed and a .020 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

Yes

→ Repair is not complete, refer to appropriate symptom.

→ Repair is complete.

POWERTRAIN VERIFICATION TEST VER - 6 - NGC

APPLICABILITY

1. Install the Miller Tool #8404 Evaporative Emission Leak Detector (EELD). according to the
instructions in the pervious DTC table.
2. Set the smoke/air control switch to AIR.
3. Insert the tester’s AIR supply tip (clear hose) into the appropriate calibration orifice on the
tester’s control panel (based on DTC leak size).
4. Press the remote smoke/air start button.
5. Position the red flag on the air flow meter so it is aligned with the indicator ball.
6. When the calibration is complete, release the remote button. The EELD is now calibrated the
flow meter in liters per minute to the size leak indicated by the DTC set in the PCM.
7. Install the service port adapter #8404-14 on the vehicle’s service port.
8. Connect the Air supply hose from the EELD to the service port.
9. Press the remote button to activate AIR flow.
10. NOTE: Larger volume fuel tanks, lower fuel levels or if the vehicle is equipped
with a Flow Management Valve may indicate high flow and will require 4 to 5
minutes to fill.
11. Compare the flow meter indicator ball reading to the red flag.
12. ABOVE the red flag indicates a leak present.
13. BELOW the red flag indicates a sealed system.
14. If the indicator ball shows a leak present, perform the smoke test indicated in the previous
test and identify the leak and repair. Perform this verification test when the repair is complete.
Did the indicator ball indicate the a leak is present??

All

Yes

→ Repeat the DTC test to identify the leak and repair.

→ Repair is complete.

SKIS VERIFICATION

APPLICABILITY

1. Reconnect all previously disconnected components and connectors.
2. Obtain the vehicle’s unique Personal Identification Number (PIN) assigned to it’s original
SKIM. This number can be obtained from the vehicle’s invoice or Chrysler’s Customer Center
(1-800-992-1997).
3. NOTE: When entering the PIN, care should be taken because the SKIM will only
allow 3 consecutive attempts to enter the correct PIN. If 3 consecutive incorrect
PIN’s are entered the SKIM will Lock Out the DRB III for 1 hour.
4. To exit Lock Out mode, the ignition key must remain in the Run position continually for 1
hour. Turn off all accessories and connect a battery charger if necessary.
5. With the DRB III, select Theft Alarm, SKIM and Miscellaneous. Then select desired
procedure and follow the steps that will be displayed.
6. If the SKIM has been replaced, ensure all of the vehicle ignition keys are programmed to the
new SKIM.
7. NOTE: Prior to returning vehicle to the costumer, perform a module scan to be sure
that all DTC’s are erased. Erase any DTC’s that are found.
8. With the DRB III erase all DTC’s. Perform 5 ignition key cycles leaving the key on for at least
90 seconds per cycle.
9. With the DRB III, read the SKIM DTC’s.
Are there any SKIM DTC’s?

All

Yes

→ Repair is not complete, refer to appropriate symptom.

→ Repair is complete.
