VERIFICATION TESTS

ROAD TEST VERIFICATION - VER-2 APPLICABILITY
1. Inspect the vehicle to ensure that all engine components are properly installed and
connected. Reassemble and reconnect components as necessary.
2. If this verification procedure is being performed after a non-DTC test, perform steps 3 and
4.
3. Check to see if the initial symptom still exists. If there are no trouble codes and the symptom
no longer exists, the repair was successful and testing is now complete.
4. If the initial or another symptom exists, the repair is not complete. Check all pertinent
Technical Service Bulletins (TSBs) and return to the Symptom List if necessary.
5. For previously read DTCs that have not been dealt with, return to the Symptom List and
follow the diagnostic path for that DTC; otherwise, continue.
6. If the Engine Control Module (ECM) (diesel only) or Powertrain Control Module (PCM) has
not been changed, perform steps 7 and 8, otherwise, continue with step 9.
7. With the DRB, erase all diagnostic trouble codes (DTCs), then disconnect the DRB.
8. Turn the ignition off for at least 10 seconds.
9. Ensure no DTCs remain by performing steps 10 through 13.
10. Road test the vehicle. For some of the road test, go at least 64 km/h (40 MPH). If this test
is for an A/C Relay Control Circuit, drive the vehicle for at least 5 minutes with the A/C on.
11. At some point, stop the vehicle and turn the engine off for at least 10 seconds, then restart
the engine and continue.
12. Upon completion of the road test, turn the engine off and check for DTCs with the DRB.
13. If the repaired DTC has reset, the repair is not complete. Check for any pertinent Technical
Service Bulletins (TSBs) and return to the Symptom List. If there are no DTCs, the repair was
successful and is now complete.
Are any DTCs or symptoms remaining?All
Ye s®Repair is not complete, refer to appropriate symptom.
No®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
PINs 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 DRBIIIt, select Theft Alarm, SKIM and Miscellaneous. Then, select the 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 customer, perform a module scan to be
sure that all DTCs are erased. Erase any DTCs that are found.
8. With the DRBIIIt, erase all DTCs. Perform 5 ignition key cycles leaving the key on for at
least 90 seconds per cycle.
9. With the DRBIIIt, read the SKIM DTCs.
Are there any SKIM DTCs?All
Ye s®Repair is not complete, refer to appropriate symptom.
