2002 Jeep Grand Cherokee OverlandFACTORY OEM SERVICE PROCEDURE

Skis Verification

  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. 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 DRBIII(R) 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. Using the DRBIII(R), 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. 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. Using the DRBIII(R), erase all DTCs. Perform 5 ignition key cycles leaving the key on for at least 90 seconds per cycle.
  9. Using the DRBIII(R), read the SKIM DTCs. Are there any SKIM DTCs? If yes, repair is not complete. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION  table in RETRIEVING & CLEARING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM. If no, repair is complete.
